The magnitude of the electric field due to a point charge object at a distance 4.0 m is 9 N/C. From the same
charged object the electric field of magnitude, 16 N/C will be at a distance of

Answers

The electric field of magnitude 16 N/C will be at a distance of 6.0 meters from the charged object.

The magnitude of the electric field due to a point charge object follows the inverse square law, which states that the magnitude of the electric field is inversely proportional to the square of the distance from the charged object. Mathematically, this is expressed as:

\(E = k*q/r^2\)

where E is the electric field, k is Coulomb's constant (\(k = 9 x 10^9 N*m^2/C^2\)), q is the charge of the object, and r is the distance from the object.

We can use this formula to find the distance at which the electric field has a magnitude of 16 N/C. Let's call this distance x:

16 = \(k*q/x^2\)

We can rearrange this equation to solve for x:

x = \(\sqrt(k*q/16)\)

To find q, we need another piece of information. We know that the electric field has a magnitude of 9 N/C at a distance of 4.0 m. Using the same formula as before, we can solve for q:

9 = \(k*q/4^2\)

q = \(9*4^2/k\)

Now we can substitute this value for q into the equation for x:

x =\(\sqrt(k*(9*4^2/k)/16)\)

x =\(\sqrt(9*4^2/16)\)

x = \(\sqrt(36)\)

x = 6.0 meters

Therefore, the electric field of magnitude 16 N/C will be at a distance of 6.0 meters from the charged object.

Voltage depends on the amount of resistance, current according to the Ohm's law, and, by definition, is the measurement of electrical pressure.

According to the Ohm's Law,  the current through a conductor between two points is directly proportional to the voltage across the two points.

Mathematically,

V ∝ I

V = IR

where, R is the resistance of the conductor and I is the current flowing in the conductor. So, the voltage depends on the amount of resistance and current.

Also, Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light.

A roller coaster car is going over the top of a 15-m-radius circular rise. The passenger in the roller coaster has a true weight of 600 N (therefore a mass of 61.2 kg). At the top of the hill, the passengers "feel light," with an apparent weight of only 360 N. How fast is the coaster moving

Answers

Answer:

v = 7.67 m/s

Explanation:

The equation for apparent weight in the situation of weightlessness is given as:

Apparent Weight = m(g - a)

where,

Apparent Weight = 360 N

m = mass passenger = 61.2 kg

a = acceleration of roller coaster

g = acceleration due to gravity = 9.8 m/s²

Therefore,

360 N = (61.2 kg)(9.8 m/s² - a)

9.8 m/s² - a = 360 N/61.2 kg

a = 9.8 m/s² - 5.88 m/s²

a = 3.92 m/s²

Since, this acceleration is due to the change in direction of velocity on a circular path. Therefore, it can b represented by centripetal acceleration and its formula is given as:

a = v²/r

where,

a = centripetal acceleration = 3.92 m/s²

v = speed of roller coaster = ?

r = radius of circular rise = 15 m

Therefore,

3.92 m/s² = v²/15 m

v² = (3.92 m.s²)(15 m)

v = √(58.8 m²/s²)

v = 7.67 m/s

Two blocks are sliding on a horizontal frictionless surface with velocities shown in the sketch. Block A has mass 0.500 kg and block B has mass 0.750 kg. The two blocks have a perfectly inelastic collision and stick together after the collision.
(a) What is the speed of the combined blocks after the collision?
(b) What angle does the velocity of the combined blocks make with the +x-axis after the collision?
(c) What is the magnitude of the decrease in kinetic energy of the system of two blocks due to the collision?

Two blocks are sliding on a horizontal frictionless surface with velocities shown in the sketch. Block

Answers

(a) The conservation of momentum applies to this inelastic collision. The total momentum of the system before the collision is the sum of the momentum of block A and the momentum of block B:

p_i = m_A * v_A + m_B * v_B

= (0.500 kg)(4.00 m/s) + (0.750 kg)(-2.50 m/s)

= 0.500 kg * 4.00 m/s - 0.750 kg * 2.50 m/s

= 0.500 kg * 4.00 m/s + (-0.750 kg) * (-2.50 m/s) (note: v_B is negative)

= 1.250 kg m/s

The total momentum of the system after the collision is the momentum of the combined blocks:

p_f = (m_A + m_B) * v_f

where v_f is the velocity of the combined blocks after the collision. Since the blocks stick together after the collision, they move with the same velocity. Therefore, we can write:

v_f = p_f / (m_A + m_B)

= 1.250 kg m/s / (0.500 kg + 0.750 kg)

= 1.00 m/s

Therefore, the speed of the combined blocks after the collision is 1.00 m/s.

(b) The angle that the velocity of the combined blocks makes with the +x-axis after the collision can be found by using the conservation of momentum in the x and y directions separately. Since there is no external force acting on the system in either the x or y direction, the total momentum in each direction is conserved.

In the x direction, the momentum before the collision is:

p_i,x = m_A * v_A,x + m_B * v_B,x

= (0.500 kg)(4.00 m/s) + (0.750 kg)(-2.50 m/s)

= 0.500 kg * 4.00 m/s - 0.750 kg * 2.50 m/s

= 0.500 kg * 4.00 m/s + (-0.750 kg) * (-2.50 m/s) (note: v_B,x is negative)

= 1.250 kg m/s

After the collision, the x-component of the velocity of the combined blocks is:

v_f,x = p_f,x / (m_A + m_B)

Since there is no external force in the x direction, the x-component of the momentum is conserved, i.e., p_i,x = p_f,x. Therefore, we can write:

p_f,x = m_A * v_f,x + m_B * v_f,x

= (m_A + m_B) * v_f,x

= 1.250 kg m/s

Substituting the values, we get:

v_f,x = 1.250 kg m/s / (0.500 kg + 0.750 kg)

= 1.00 m/s

In the y direction, the momentum before the collision is:

p_i,y = m_A * v_A,y + m_B * v_B,y

= 0 + 0

= 0

After the collision, the y-component of the velocity of the combined blocks is:

v_f,y = p_f,y / (m_A + m_B)

Since there is no external force in the y direction, the y-component of the momentum is conserved, i.e., p_i,y = p_f,y. Therefore, we can write:

p_f,y = m_A * v_f,y + m_B * v_f,y

= (m_A + m_B) * v_f,y

Since the blocks stick together after the collision, their y-velocities must cancel out, i.e., v_f,y = 0. Therefore, we can write:

0 = (m_A + m_B) * v_f,y

Substituting the values, we get:

v_f,y = 0

Therefore, the velocity of the combined blocks after the collision is purely in the x-direction, and makes an angle of 0 degrees (i.e., is parallel to) with the +x-axis.

(c) The kinetic energy of the system before the collision is:

KE_i =\((1/2) * m_A * v_A^2 + (1/2) * m_B * v_B^2\)

=\((1/2) * (0.500 kg) * (4.00 m/s)^2 + (1/2) * (0.750 kg) * (-2.50 m/s)^2\)

= \(2.000 J + 2.344 J\)

= 4.344 J

The kinetic energy of the system after the collision is:

KE_f = (1/2) * (m_A +m_B) * v_f^2

= (1/2) * (0.500 kg + 0.750 kg) * (1.00 m/s)^2

= 0.937 J

Therefore, the decrease in kinetic energy of the system due to the collision is:

ΔKE = KE_i - KE_f = 4.344 J - 0.937 J = 3.407 J

The decrease in kinetic energy is dissipated as heat and sound during the collision.

The kinetic energy of electron is

Using conservation of energy

\(mgh=\dfrac{1}{2}mv_{i}^2\)

\(E=\dfrac{1}{2}mv_{i}^2\)

\(7000=\dfrac{1}{2}mv_{i}^2\)

\(\dfrac{1}{2}mv_{i}^2= 7000\ V\)

When an electron passing through field E experience force F produces change in momentum.

Answers

Answer:

Temperature of the air in the balloon = 272°C

Explanation:

Given:

Volume of balloon = 500 m³

Air temperature = 15° C = 273 + 15 = 288 K

Total weight = 290 kg

Density of air = 1.23 kg/m³

Find:

Temperature of the air in the balloon

Computation:

Density of hot air = Density of air - [Total weight / Volume of balloon]

Density of hot air = 1.23 - [290 - 500]

Density of hot air = 0.65 kg/m³

[Density of hot air][Temperature of the air in the balloon] = [Density of air][Air temperature ]

Temperature of the air in the balloon = [(1.23)(288)]/(0.65)

Temperature of the air in the balloon = 544.98

Temperature of the air in the balloon = 545 K

Temperature of the air in the balloon = 545 - 273 = 272°C

Temperature of the air in the balloon to lift a total load of 290 kg is 272°C.

What is temperature?

Temperature is the degree of hotness or coldness of the object.

Given is Volume of balloon = 500 m³, Air temperature = 15° C = 273 + 15 = 288 K

Total weight = 290 kg and Density of air = 1.23 kg/m³

Density of hot air = Density of air - [Total weight / Volume of balloon]

Density of hot air = 1.23 - [290 - 500]

Density of hot air = 0.65 kg/m³

Density is inversely proportional to the temperature.

[ρ hot air] x [T air in the balloon] = [ρ air] x [T air ]

Putting the values, we get temperature of the air in the balloon is

T air = [(1.23)(288)]/(0.65)

T air in Kelvin is 545 K

T air in Celcius is  545 - 273 = 272°C.

Cass yanks on the chain with a 67 N force at an angle of 30° above the horizontal. Determine the horizontal and vertical components of the tension force.

Answers

Answer:

Horizontal component: \(F_x = 58\ N\)

Vertical component: \(F_y = 33.5\ N\)

Explanation:

To find the horizontal and vertical components of the force, we just need to multiply the magnitude of the force by the cosine and sine of the angle with the horizontal, respectively.

Therefore, for the horizontal component, we have:

\(F_x = F * cos(angle)\)

\(F_x = 67 * cos(30)\)

\(F_x = 58\ N\)

For the vertical component, we have:

\(F_y = F * sin(angle)\)

\(F_y = 67 * sin(30)\)

\(F_y = 33.5\ N\)

So the horizontal component of the tension force is 58 N and the vertical component is 33.5 N.

A remote control boat with a mass of 4.5 kg starts at rest. A propeller performs 300 joules of work on the boat. What is the boats final velocity ?

Answers

The boat's final velocity can be determined using the work-energy principle. Since the boat starts at rest, the work done on it will be equal to its change in kinetic energy.

Using the equation:

Work = Change in Kinetic Energy

300 J = (1/2) * m * v^2

where m is the mass of the boat and v is the final velocity, we can solve for v.

Plugging in the values:

300 J = (1/2) * 4.5 kg * v^2

Simplifying the equation:

v^2 = (2 * 300 J) / 4.5 kg

v^2 = 200 J / 4.5 kg

v^2 = 44.44 m^2/s^2

Taking the square root of both sides:

v = √(44.44 m^2/s^2)

v ≈ 6.66 m/s

Therefore, the boat's final velocity is approximately 6.66 m/s.

F_y = G(½m)(mt) / (¼r)²

F_y = ½(Gm(mt) / (¹/₁₆ r²)

F_y = (16 Gm mt)/(2r²)

F_y = 8(G m(mt) ) / r²

F_y = 8(F_X)

F_X = ¹/₈(F_Y)

The first P-wave of an earthquake travels 5600 kilometers from the epicenter and arrives at a seismic station at 10:05 a.m. At what time did this earthquake occur?

Ahhhhhh I have a Regent's test in 2 hours and I don't know how to solve this type of question! Any help would be appreciated.

Anyone know what the steps to do this are? I dont even need an answer, just how to get to it. Thank you!

Answers

The earthquake would occur 13 minutes before 10:05 a.m. which will be at 9.52 am.

The p-waves travel with a constant velocity of 7 km/s

The time can be calculated by using the formula

t = d / v

where

T1 =  10:05 a.m

d is the distance they take to travel from the epicenter

v is the speed of the p-waves

On average, the speed of p-waves is

v = 7 km/s

d = 5600 km (given)

Substituting the values in the formula;

t = d / v

t = 5600 ÷ 7

t = 800 seconds

Converting into minutes,

t = 800 ÷ 60

t = 13.3

≈ 13 mins

T1 -  13 mins = T2

10:05 - 13 mins = 9.52 am

It means the earthquake occurred prior 13 minutes, that is at 9.52 am.

Therefore, the earthquake occurred at 9.52 am.

Define invariant transformations

Answers

Answer:

For a given system, there can be particular transformations for which the explicit equations of motion are the same for both the old and new variables. Transformations for which the equations of motion are invariant, are called invariant transformations. It will be shown that if the Lagrangian does not explicitly contain a particular coordinate of displacement  qi, then the corresponding conjugate momentum,  pi, is conserved. This relation is called Noether’s theorem which states “For each symmetry of the Lagrangian, there is a conserved quantity".
