IF a particular galaxy has a total mass of 10 to the 47 grams and the average star in that galaxy has a mass of 10 to the 33
grams, approximately how many stars are there in that galaxy? Give your answer to the nearest whole power of 10 by
entering the exponent only.

Answers

The number of stars present in the galaxy is 10 raised to the power of 14. So the exponent is equal to 14.

Given in the question

Total mass of the particular galaxy = 10 to the power of 47 grams

The average mass of the star in the galaxy = 10 to the power of 33 grams

We know that the total mass of the galaxy which is a collection of several thousand stars is equal to the sum of all the stars present in it. Also, the total mass of the galaxy can be calculated by multiplying the average mass of a star in the galaxy by the number of stars that are there in the galaxy.

So, Total mass = Average mass × Number of stars in the galaxy

Number of stars in the galaxy = Total mass of the galaxy/ Average mass of the star

Put in the values, we get

Number of stars in the galaxy = 10^47/10^33

Number of stars in the galaxy = 10^(47-33)

Number of stars in the galaxy = 10^14

So, the number of stars present in the galaxy is 10 raised to the power of 14. So the exponent is equal to 14.

Answers

Each bulb will stay at the same brightness position as before. When a wire is connected between points 1 and 2 the circuit becomes a parallel circuit.

In a parallel circuit, the voltage across each bulb remains the same, and each bulb will remain at the same brightness position as before. The wire was connected assuming that the voltage supplied to the circuit remains constant. The overall resistance in the circuit will drop due to the added wire, so the total current supplied by the voltage source will increase.

This increased current will be divided between the bulb so each bulb will admit a slightly advanced current than earlier but not enough to create a noticeable increase in lightness. thus, each bulb will stay at the same brightness position as before.

what happens to the ballon when you squeeze the bottle?

Answers

Answer:

When you squeeze a bottle that has a balloon attached to its opening, the pressure inside the bottle increases. This increased pressure will cause the air molecules inside the bottle to move closer together, which in turn will cause the balloon to inflate.

If you continue to squeeze the bottle, the pressure inside the bottle will continue to increase, and the balloon will continue to inflate. However, if you squeeze the bottle too hard, the balloon may burst due to the excess pressure.

When you release the pressure on the bottle, the air molecules inside the bottle will spread out again, causing the pressure to decrease. As a result, the balloon will deflate back to its original size.

A 4.5 kg bucket of water is raised from a well by a rope. The acceleration of gravity is 9.81 m/s 2 . If the upward acceleration of the bucket is 4.9 m/s2 , find the force exerted by the rope on the bucket of water. Answer in units of N.

Answers

Answer:

The force exerted by the rope on the bucket of water is 66.195 N.

Explanation:

Given;

mass of the bucket, m = 4.5 kg

acceleration of gravity, g = 9.81 m/s²

upward acceleration of the bucket, a = 4.9 m/s²

The upward force applied on the bucket by the rope is calculated as;

F = ma + mg

F = m(a + g)

F = 4.5(4.9 + 9.81)

F = 4.5(14.71)

F = 66.195 N

Therefore, the force exerted by the rope on the bucket of water is 66.195 N.

Which of the following describes what caused the change in tides between 6:00 a.m. and noon that day

options :  

A)The Earth revolved approximately 90° around the Sun, and the gravitational attraction between the Moon and Sun increased.

B)The Earth completed one full rotation (360°), and the gravitational attraction between the Moon and the Beachview area increased.

C)The Earth completed one full revolution around the Sun (360°), and the gravitational attraction between the Moon and Sun decreased.

D)The Earth rotated approximately 90°, and the gravitational attraction between the Moon and the Beachview area decreased.

answer :  

The Earth rotated approximately 90°, and the gravitational attraction between the Moon and the Beachview area decreased.  ( D )

Explanation:

The movement of the Earth in the Galaxy occurs in two ways

namely: Rotation and Revolution and each movement comes has an effect on the earth, also each movement has a time frame as well.

The complete rotation of the earth about its axis takes about 24 hours and this rotation brings about Night and day and it also causes the rise and fall of tides. while the Revolution of the earth round brings about different seasons and it takes about 365 days for a complete revolution of the earth round the sun.

hence the the change in tides between 6:00 a.m. and noon that day is caused by The Earth rotating approximately 90°, and the gravitational attraction between the Moon and the Beachview area decreased.

A ball is thrown straight up 25 m/s, if it lands 10 seconds later, how high is the building?

Answers

Answer:

Explanation:

To determine the height of the building, we can use the kinematic equation for vertical motion:


h = v₀t + (1/2)gt²


Where:

h is the height of the building

v₀ is the initial velocity of the ball (25 m/s)

t is the time taken for the ball to reach the ground (10 seconds)

g is the acceleration due to gravity (approximately 9.8 m/s²)


Plugging in the values:


h = (25 m/s)(10 s) + (1/2)(9.8 m/s²)(10 s)²

h = 250 m + (1/2)(9.8 m/s²)(100 s²)

h = 250 m + 490 m

h = 740 m


Therefore, the height of the building is approximately 740 meters.

Q. 3. A body of mass 3 kg moves with a velocity of 500 cm/s, the momentum of the
body is _______. (a) 150 kg m/s (b) 15 x 109 kg m/s
(c) 15 x 10-9 kg m/s (d) 15 kg m/s

Answers

According to the given statement the momentum of the body is 15 kg m/s. Answer: (d) 15 kg m/s

The momentum of a body can be calculated by multiplying its mass by its velocity.

In this case, the mass of the body is given as 3 kg and the velocity is given as 500 cm/s.

To find the momentum, we first need to convert the velocity from centimeters per second to meters per second.

Since 1 meter is equal to 100 centimeters, we divide the velocity by 100 to get the velocity in meters per second.

Therefore, the velocity of the body is 500 cm/s ÷ 100 = 5 m/s.

Next, we multiply the mass of the body (3 kg) by its velocity (5 m/s) to find the momentum.

Momentum = mass × velocity
        = 3 kg × 5 m/s
        = 15 kg m/s

Therefore, the momentum of the body is 15 kg m/s.

Answer: (d) 15 kg m/s


The formula to calculate momentum is mass × velocity.

In this question, the mass of the body is given as 3 kg and the velocity is given as 500 cm/s.

However, we need to convert the velocity to meters per second before calculating the momentum.

After converting, we multiply the mass by the velocity to find the momentum, which is 15 kg m/s.


The momentum of the body is 15 kg m/s.

During take-off a 8kg model rocket, initially at rest, burns fuel for 6.3s causing its speed to increase from rest to 60m/s during this time despite experiencing a 50N drag.

What is the magnitude of the net force on the rocket?
What is the strength of the thrust?
What is the magntiude of the rocket's acceleration?
What is the rocket's height at the instant it runs out of fuel?

Answers

The rocket attains a speed of 60 m/s in a matter of 6.3 s, so it is undergoing an acceleration a of

a = (60 m/s - 0) / (6.3 s) ≈ 9.52 m/s²

During launch, the only forces acting on the rocket are directed vertically:

• its weight (pointing down) with magnitude W,

• drag (pointing down) with magnitude 50 N, and

• thrust (pointing up) with magnitude T.

(a) By Newton's second law, the magnitude of the net force is proportional to the acceleration according to

F = m a

where m is the mass of the rocket, so the magnitude of the net force is

(8 kg) (9.52 m/s²) ≈ 76.2 N

and it is directed upward.

(b) Expanding the equation from part (a) gives

T - W - 50 N = (8 kg) (9.52 m/s²)

The weight is

W = (8 kg) g = (8 kg) (9.80 m/s²) = 78.4 N

so the thrust force is

T ≈ 76.2 N + 78.4 N + 50 N ≈ 205 N

(c) We found this earlier, a9.52 m/s².

(d) The rocket's height y at time t is given by

y = 1/2 a t ²

so that after 6.3 s, it will have reached a height of

y = 1/2 (9.52 m/s²) (6.3 s)² = 189 m

Which will not be affected by the induced e.m.f when a magnet is in motion relative to a coil? A. Motion of the magnet B. Resistance of the coil C. Number of turns of the coil D. The strength of the magnet pole

Answers

The strength of the magnet pole (option D) will not be affected by the induced electromotive force (e.m.f) when a magnet is in motion relative to a coil.

When a magnet is in motion relative to a coil, it induces an electromotive force (e.m.f) in the coil due to the changing magnetic field. This induced e.m.f. can cause various effects, but it does not directly affect the strength of the magnet pole (option D). Option A, the motion of the magnet, is directly related to the induction of the e.m.f. When the magnet moves, the magnetic field through the coil changes, inducing the e.m.f.

Option B, the resistance of the coil, affects the amount of current flowing through the coil when the e.m.f is induced. Higher resistance can limit the current flow. Option C, the number of turns of the coil, affects the magnitude of the induced e.m.f. More turns increase the induced voltage.

However, the strength of the magnet pole (option D) itself is independent of the induced e.m.f. It is determined by the properties of the magnet, such as its magnetization and magnetic material. The induced e.m.f does not alter the intrinsic strength of the magnet pole.

Answers

A ball which is most likely to topple the bowling pin is: 2. the rubber ball.

What is the law of conservation of momentum?

The law of conservation of momentum states that the total linear momentum of an isolated (closed) system would always remain constant (the same) with respect to time, unless an external force is applied.

Additionally, the law of conservation of momentum states that the total momentum of two interacting objects in an isolated (closed) system would be the same or remain constant, provided no external force is applied.

In this scenario, we can logically deduce that momentum is conserved in the interaction between the large wooden bowling pin and a ball, but more momentum would be transferred from the rubber ball to the bowling pin, rather than from the putty ball to the rubber ball.

In conclusion, the rubber ball is more likely to topple the bowling pin over because it acts as an external force.

L= 1 H and R = 3.9 KQ. V (w) Vi (w) b) Sketch the magnitude of the frequency response function H(w). c) Determine what type of ideal filter is approximated by this circuit. a) Find H (w) = + vi(t) L R + vo(t)

Answers

The circuit has a constant gain of 1 for high frequencies, implying that it acts as a low-pass filter. To find the frequency response function H(w) for the given circuit, we need to determine the transfer function H(w) = V0(w) / Vi(w), where V0(w) is the output voltage and Vi(w) is the input voltage in the frequency domain.

L = 1 H (inductance)

R = 3.9 KΩ (resistance)

The circuit can be represented by the following equation:

H(w) = (jwL + R) / (jwL + R + 1)

To sketch the magnitude of the frequency response function H(w), we need to plot the magnitude |H(w)| as a function of frequency w.

Taking the magnitude of the transfer function, we have:

|H(w)| = |(jwL + R) / (jwL + R + 1)|

Next, let's analyze the type of ideal filter approximated by this circuit. We can examine the transfer function to determine the filter characteristics.

From the transfer function:

H(w) = (jwL + R) / (jwL + R + 1)

As w approaches infinity, the jwL term dominates the transfer function, and the transfer function becomes:

H(w) ≈ jwL / jwL = 1

This indicates that the circuit has a constant gain of 1 for high frequencies, implying that it acts as a low-pass filter. It allows low-frequency signals to pass through relatively unattenuated while attenuating high-frequency signals.

Calculate the current of a 10m wire which has a resistance of 0. 5W/km. The power passing through the wire is 45W

Answers

The current passing through the wire is approximately 424.26 A.

R = (0.5 W/km) x (10m/1000m) = 0.005 Ω

Next, we can use the formula for power in terms of current and resistance:

P = I^2 R

Rearranging the formula to solve for current, we get:

I = sqrt(P/R) = sqrt(45 W / 0.005 Ω) ≈ 424.26 A

Resistance arises due to the interactions between the electrons in a material and the atoms that make up that material. When an electric current flows through a material, the electrons collide with the atoms, which impedes their flow and generates resistance. The greater the number of collisions, the greater the resistance.

Resistance can be affected by various factors such as the type of material, the cross-sectional area of the conductor, and the temperature. The relationship between current, voltage, and resistance is described by Ohm's Law, which states that the current flowing through a conductor is directly proportional to the voltage applied and inversely proportional to the resistance of the conductor.

= 297.6 N

An external force is a physical influence that originates from outside a system and affects its behavior. In physics, a system is defined as a collection of objects or particles that are being studied or analyzed, and external forces are any forces that are not part of the system itself. These forces can come from a variety of sources, such as other objects, fields of energy, or the environment.

External forces can have a significant impact on a system's motion and behavior, and are often used in physics to model real-world phenomena. For example, the force of gravity acting on an object is an external force, as it is caused by the Earth's mass and affects the object's motion. Similarly, the force of air resistance acting on a moving object is an external force that can slow it down.

When the filament breaks in one lamp in a series circuit, other lamps in the circuit normally _______.
a) continue glowing as brightly
b) continue glowing, but more dimly
c) absorb energy from the damaged lamp
d) go out

Answers

When the filament breaks in one lamp in a series circuit, other lamps in the circuit normally go out. This is because in a series circuit, the lamps are connected in a single pathway such that the current flows through each lamp in turn. When one lamp fails, it creates an open circuit, which means that the current can no longer flow through the rest of the circuit.

As a result, all of the other lamps in the circuit will also stop working. It is worth noting that in a parallel circuit, each lamp is connected to the power source independently, so if one lamp fails, the other lamps will continue to work normally. However, in a series circuit, the failure of one component can cause the entire circuit to stop working, which makes it less reliable than a parallel circuit.

what force pushes groundwater from pore space to pore space when below the water table?

Answers

The force that pushes groundwater from pore space to pore space when below the water table is primarily due to the pressure gradient within the aquifer. This pressure gradient is caused by the weight of the overlying water and the force of gravity.

Below the water table, the spaces between soil or rock particles are filled with water. These spaces are known as pore spaces. The water table represents the upper surface of the saturated zone, where all the pore spaces are filled with water. gravity acts vertically downward, causing the weight of the water above a particular point to exert a downward force. As a result, the water pressure increases with depth. This increase in pressure creates a pressure gradient within the aquifer.

The pressure gradient drives the flow of groundwater from areas of higher pressure to areas of lower pressure. When a well is drilled into the aquifer below the water table, water will naturally flow into the well and rise to the level of the water table. This is because the pressure is higher below the water table compared to the lower pressure in the well.

The movement of groundwater from pore space to pore space occurs due to the pressure difference between adjacent spaces. Water will flow from areas of higher pressure to areas of lower pressure until the pressures equalize. This movement of water is known as groundwater flow or hydraulic conductivity.

Calculate the speed of the waves if the distance between wave crests is 1.3 meters.​

Answers

The speed of the waves is dependent on the frequency and wavelength of the waves. Without knowing the frequency, we cannot accurately calculate the speed of the waves.

What are some factors that can affect the speed of waves?

The speed of waves can be affected by several factors, including the density, viscosity, and elasticity of the medium through which they are traveling. In general, waves travel faster through denser and more elastic mediums, and slower through less elastic and more viscous mediums. For example, sound waves travel faster through solids than through gases because solids are denser and more elastic than gases.

What are some practical applications of wave speed calculations?

Wave speed calculations have many practical applications in fields such as acoustics, optics, and telecommunications. For example, the speed of sound waves can be used to calculate the distance to an object using sonar or ultrasound technology.
