what is the trend on the graph

Answer:

43.88 meters per second

Explanation:

The computation of the speed is shown below:

As we know that

\(Speed = \frac{Distance}{time}\)

where,

Distance is 395,000 meters

Time is 9,000 seconds

Now placing these values to the formula

So, the speed is

\(= \frac{395,000}{9,000}\)

= 43.88 meters per second

As speed shows the relation between the distance and time and the same is to be considered i.e by applying the formula

The diameter of the stream below the opening of the faucet is 1.94 cm.

The diameter of the stream can be found using the formula for the velocity of steady flow in a cylindrical stream:

v = Q / (πr²)

Where Q is the volume flow rate (volume per time), v is the velocity, and r is the radius of the stream.

By rearranging this equation and using the known values of the volume and time, find the radius of the stream 13.0 cm below the opening of the faucet:

r² = Q / (πv) = (125 cm³) / (π x (13.0 cm)² / 4)

r = √(125 / (π x (13.0 cm)² / 4)) = 0.97 cm

2r = 2 x 0.97cm = 1.94 cm

So the diameter of the stream 13.0 cm below the opening of the faucet would be 1.94 cm.

Explanation:

The expression \(X^{N} + Y^{N}\)is not divisible by X - Y (where Y is not equal to 0).

To determine whether the expression \(X^{N} + Y^{N}\) is divisible by X - Y (where Y is not equal to 0), we can use the factor theorem and the property of binomial expansion.

The factor theorem states that if a polynomial P(x) is divisible by (x - a), then P(a) equals zero. In our case, if \(X^{N} + Y^{N}\) is divisible by (X - Y), then when we substitute X = Y into the expression, the result should be zero.

Let's substitute X = Y into the expression:

\(Y^{N} + Y^{N}\)

Since \(Y^{N}\) is equivalent to \(Y^{N}\) , the expression becomes:

2(\(Y^{N}\))

We can see that the expression 2(\(Y^{N}\)) is not equal to zero unless Y is equal to zero. Therefore, if Y is not equal to zero, \(X^{N} + Y^{N}\) is not divisible by X - Y.

In summary, unless Y is equal to zero, the expression \(X^{N} + Y^{N}\) is not divisible by X - Y according to the factor theorem and the given condition.

The direction of the current from the positive to the negative battery terminals and the fact that the bulbs are connected in parallel to each other suggests that this circuit is a Closed Parallel Circuit. The correct option is D.

An open circuit and a closed circuit are two types of electrical circuits that describe the flow of electrical current through a circuit.

An open circuit is a circuit in which there is a break in the path of the current, meaning that the current cannot flow through the circuit. In an open circuit, the switch is in the "off" position or there is a broken wire, and so no electrical current can flow through the circuit. This means that there is no voltage or electrical energy being transferred from the source to the load.

On the other hand, a closed circuit is a circuit in which there is a complete path for the current to flow through, meaning that the current can flow through the circuit. In a closed circuit, the switch is in the "on" position, and there is a continuous path for the current to flow from the source to the load and back to the source. This means that there is voltage and electrical energy being transferred from the source to the load.

Here in this question,

The direction of the current from the positive to the negative battery and the fact that the bulbs are connected in parallel to each other suggests that this circuit is a Closed Parallel Circuit.

In a closed parallel circuit, the components are connected in parallel to each other, meaning that they are connected to the same two points in the circuit and the current has multiple paths to flow through. The voltage across each component is the same, and the total current flowing through the circuit is divided among the components according to their resistance.

In contrast, an open series circuit is a circuit in which the components are connected in series, meaning that they are connected end to end in a single path, with no other branch points for the current to follow. If one component fails, the circuit becomes open and the current stops flowing.

Therefore, based on the information provided, the circuit described in the question is a Closed Parallel Circuit.

The man's friend is at a distance 552.5 m away.

Speed of sound in air, v = 340 m/s

Time after which the echo is heard, t = 3.25 s

The expression for the total distance covered by the sound in the given time,

d = v x t

d = 340 x 3.25

d = 1105 m

Therefore, the distance where the friend is staying would be half of the total distance covered by the sound during the given time.

Answer:

She will be going at 11.01 m/s when she reaches the bottom.      

Explanation:

We can find the speed at the bottom by equating the total work with the change in energy:

\( W = E_{f} - E_{i} \)   (1)

There is no energy conservation because there is a force of friction on her way down.  

By entering \(W = -F_{\mu}*d\), where \(F_{\mu}\) is the force of friction (is negative because it is in the opposite direction of motion) and d is the displacement, into equation (1) we have:

\(-F_{\mu}*d = E_{f} - E_{i}\)  

In the initial state, we have kinetic and potential energy and in the final state, we have only kinetic energy.

\(-F_{\mu}*d = \frac{1}{2}mv_{f}^{2} - (\frac{1}{2}mv_{i}^{2} + mgh)\)  

Where:

m: is the total mass = 40 kg

\(v_{f}\): is the final speed =?

\(v_{i}\): is the intial speed = 5 m/s

g: is the gravity = 9.81 m/s²

h: is the height = 10 m

\( -20 N*100 m = \frac{1}{2}40 kg*v_{f}^{2} - \frac{1}{2}*40 kg*(5 m/s)^{2} - 40 kg*9.81 m/s^{2}*10 m \)    

By solving the above equation for \(v_{f}\) we have:

\( v_{f} = 11.01 m/s \)      

Therefore, she will be going at 11.01 m/s when she reaches the bottom.

Newton's second law tells us that force is directly proportional to mass and acceleration, such that:

Where force is measured in newtons (N).

The three fundamental laws of Newton are:

Newton's laws are fundamental to understanding the interaction between bodies. Today they are still valid, although at the atomic level it has some exceptions that quantum mechanics studies.

Data:

m = 7.5 kg

F = ?

a = 3.2 m/s²

The formula to calculate the force is: F = m * a

We clear, but in this case it is not necessary, since we only want to calculate the force.

The force you need to accelerate down the alley is 24 Newtons.

a) angular speed is 0.2513 rad/s

b)  linear speed is  3.77 m/s

c) centripetal acceleration is 0.95 m/s²

d) the normal force of the seat on you at the top of the Ferris Wheel is  809.25 N

e) the normal force of the seat on you at the bottom of the Ferris Wheel is 701.25 N

We have , angular speed, ω = 2π/T, where, T = time to go around once = 25 seconds

linear speed, v = rω, where, r = radius of the Ferris Wheel,

centripetal acceleration, ac = v²/rc, where, v = linear speed and r = radius of the Ferris Wheel

normal force, N = mg + mac, where, m = mass of the rider, g = acceleration due to gravity and ac = centripetal acceleration(a)

a) angular speed, ω = 2π/T= 2 × π/25= 0.2513 rad/s

b)  linear speed, v = rω

v = 15 × 0.2513= 3.77 m/s

c) centripetal acceleration, ac = v²/rc

ac = (3.77)²/15

ac = 0.95 m/s²

(d) At the top of the Ferris Wheel, the normal force is given by:

N = mg + mac

N = 75 × 9.8 + 75 × 0.95

N = 809.25 N

(e) At the bottom of the Ferris Wheel, the normal force is given by:

N = mg - mac

N = 75 × 9.8 - 75 × 0.95

N = 701.25 N

Therefore, the normal force of the seat on you at the top of the Ferris Wheel is 809.25 N and at the bottom is 701.25 N.

The most important distinction between area and perimeter is: The term "perimeter" refers to the length of the shape's outer boundary, while "area" refers to the area that the shape occupies. The size of a shape is determined by both parameters. A two-dimensional equable shape, also known as a perfect shape, has an area that is numerically equal to its perimeter.

Explanation:

The average time taken by the car to cover a distance of 0.25 meters and 0.50 meters which is based on the three trial times are :

Distance of 0.25 meters = 2.23 seconds

Distance of 0.50 meters = 3.13 seconds

Distance is defined as a numerical or sometimes a qualitative measure of how far objects or points are. Distance can be described as a physical length or as an approximation based on other criteria.

It can be calculated by:

Distance= Speed x time

Where, Distance is in Meter or kilometer

Speed is in meter per second or km/min

Time is in seconds or minutes

From the above formula, we can also calculate the time like for above given information,

Average travel time to cover 0.25 meters :

(Trial 1 time + Trial 2 time + Trial 3 time) ÷ 3

(2.24 + 2.21 + 2.23) ÷ 3

(6.68 ÷ 3) = 2.226667 = 2.23 seconds

Average travel time to cover 0.50 meters :

(Trial 1 time + Trial 2 time + Trial 3 time) ÷ 3

(3.16 + 3.08 + 3.15) ÷ 3

9.39 ÷ 3 = 3.13 seconds

Thus, the average time taken to cover 0.25 and 0.50 meters are 2.23 and 3.13 seconds respectively

The 10/90 principle refers to the idea that life is made up of 10% of what happens to you and 90% of how you respond to it. In other words, you may not be able to control what happens to you, but you can control your reaction to it. By taking responsibility for what you can change rather than being a victim of what you cannot change, you can take control of your situation and improve your life.One example of a situation where the 10/90 principle could be applied is losing a job. Losing a job can be a devastating experience, and it can be easy to feel like a victim in this situation. However, by applying the 10/90 principle, you can take control of your situation and make positive changes in your life.The first step in applying the 10/90 principle in this situation would be to take responsibility for what you can change. This could mean updating your resume, networking with others in your field, and applying for new jobs. By taking action and doing what you can to find a new job, you are taking control of your situation and improving your chances of finding a new job.

Explanation:

Thanx for the figure;
The force component of F   UP the ramp that  moves the crate must equal the force of the crate DOWN the ramp

75 kg = mg Newtons = 735.8 Newtons

    Downplane force is   735.8 sin 34°  = 411.4 Newtons

   Fn =The horizontal force will be found by   cos 34 = 411.4/ F                                                                       F = 411.4/cos (34) = 496 N

Normal Force =  735.8 cos 34°  = 610 N   This part is due to the mass of the crate....there is additional normal force from the force pushing the crate up the hill  (from below)

   = F sin34   =  496 sin 34 = 277.4 N

            SUM of normal forces = 610 + 277.4 = 887.4 N

Answer:

  a.  |F| ≈ 496 N

  b.  normal force ≈ 887 N

Explanation:

You want the magnitude of the horizontal force F that moves a crate up a 34° ramp at constant speed, and you want the magnitude of the normal force on the crate.

The constant speed of the crate tells you the net force up the ramp is zero. This is the sum of the component of force F in that direction and the force due to gravity in the opposite direction:

  F·cos(34°) - m·g·sin(34°) = 0

  F = mg·tan(34°) = (75 kg)(9.8 m/s²)tan(34°) ≈ 496 N

The magnitude of force F is about 496 N.

The normal force on the crate will be the sum of the component of F in that direction and the force due to gravity in the same direction:

  F·sin(34°) +m·g·cos(34°) ≈ 887 N

The magnitude of the normal force is about 887 N.
