The Doppler red-shift of light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point). This allows for Big Bang Theory, because after a “bang” occurs all of the matter moves away from the point of origin.

Her jumper would appear dark and drab, practically a dark shade of gray, if Ray shone a green filter on it.

This is so because the wavelengths of light that an object reflects define its color. In the case of red clothing, it reflects red light with wavelengths between 620 and 750 nm. The green filter, however, blocks all other wavelengths, including red ones, and only allows green light wavelengths (between 495 and 570 nm) to get through when it is positioned in front of the red jumper.

We wouldn't see the colour red because red wavelengths are blocked and red clothing can't reflect them back to our eyes. Instead, we would observe the dark and dreary greyish-green color that is produced when residual green wavelengths combine with the color of the red garment.

The interaction between green filter's color wavelengths and red jumper's color wavelengths causes red jumper to appear as a dark and dreary greyish-green color when green filter is shone upon it.

When rain is falling vertically at 8m/s then the speed of the car is calculated to be 4.618 m/s.

The velocity of the raindrops adds to the velocity of the car to produce a velocity of the rain relative to the car.

As the surface becomes rougher, friction increases and on rainy days, we are more likely to slip because water acts as a lubricant between feet and the ground. Dry friction is converted to fluid friction by rainwater.  Rain drops have a uniform type of motion

Given rain is falling vertically with 8 m/s speed

and rain drop makes an angle of  30°

As we know that, tan∅ = V (horizontal) / V (vertical)

Hence,  V (horizontal)= tan ∅ *  V (vertical)

= tan (30° ) * 8

speed of the car​ = 4.618 m/s.

Answer:

Explanation:

A -heat capacity

B - continuity equation

C -pressure

D - mechanical energy

The hydro power plant consists of a (artificial) dam that builds gravitational potential energy, P.E. from natural flowing water sources, by locating the dam along the water path. The stored potential energy, P. is converted into kinetic energy, K.E. as the water falls from the dam, down to the turbines, located at a much lower level according to the following principle of conservation of energy equation;

Total Mechanical Energy, M.E. = The potential energy of the water, P.E. + The kinetic energy of the water, K.E. = Constant

M.E. = P.E. + K.E. = Constant

Where;

P.E. = m·g·h

K.E. = (1/2)·m·v²

m = Mass

g = The acceleration due to gravity

h = The height of the dam

v = The velocity

The charts can be explained as follows;

Given that the potential energy P.E. = m·g·h, we have that the potential energy is directly proportional to the height of the dam, and therefore, at mid height, the potential energy would be half the maximum value, and we have;

At mid height, P.E. = (1/2)·\(\mathbf{P.E._{max}}\)

At the top of the dam, the (vertical) velocity of the water = 0, therefore, the kinetic energy = 0

Therefore, at the top of the dam, we get;

M.E. = \(P.E._{max}\) + 0 =

M.E. = \(\mathbf{P.E._{max}}\)

Similarly, at the bottom of the dam, the height, h = 0, therefore, being proportional to the height, P.E. = 0, and the velocity is maximum, and at the bottom, we have;

M.E. = 0 + \(K.E._{max}\)

The first chart, water is halfway down the dam

At the halfway down therefore, we have;

P.E. = (1/2)·\(\mathbf{P.E._{max}}\)

M.E. = \(P.E._{max}\) = (1/2)·

∴ K.E. = \(P.E._{max}\) - (1/2)·

Therefore the first chart, water is halfway down the dam;

Halfway, K.E. = (1/2)·\(\mathbf{P.E._{max}}\) = P.E.

∴ K.E. = P.E.  as shown on the chart

The second chart, water has reached the turbine

Water reaches the turbine at the bottom, and as explained above, we get;

M.E. = 0 + \(K.E._{max}\)

∴ M.E.≈ \(K.E._{max}\)

Therefore, when water has reached the turbine at the bottom of the dam, the kinetic energy is approximately proportional to the total mechanical energy as shown in the chart

The third chart, water is at the top of the dam

Here as shown above, we have;

The total mechanical energy, M.E. ≈ \(\mathbf{P.E._{max}}\) as shown on the chart

Examples of work taking place include options 1, 2, and 3.

Work is said to be done when a force causes a displacement in an object in the direction of the force. The following situations are examples of work occurring:

Lifting a box off the ground: The force of lifting the box causes a displacement in the box in the upward direction, which is the same direction as the force applied. Therefore, work is done on the box.

Pushing a car up a hill: The force of pushing the car causes a displacement in the car in the direction of the hill, which is the same direction as the force applied. Therefore, work is done on the car.

Carrying a backpack: Although the backpack may not be moving, work is still being done because the force of carrying the backpack causes a displacement in the person's body in the upward direction.

Holding a heavy object: If a person is holding a heavy object, but not moving it, no work is being done on the object because there is no displacement. However, the person's muscles are still working to maintain the position, which is an example of isometric work.

Therefore, options 1, 2, and 3 are examples of work occurring. Option 4 is not an example of work being done on the object, but it is an example of work being done by the person's muscles.

The maximum height reached by the brick above the ground is 20 ft. The time taken by the brick to reach the ground is 0 seconds. Free-fall motion (uniformly accelerated motion) after falling from a height of 20 feet. Further, the acceleration experienced by the free brick is equal to the acceleration due to gravity which is approximately 32ft/sec², downward.

Hence, we can write its acceleration as, a = g = 32ft/sec².

Here, u = 0 as the brick was not moving initially while it was at rest on the top of the load of bricks.

Now, the value of v(t) can be obtained by integrating the above expression w.r.t. time as shown below:v(t) = u + a.t = 0 + 32t = 32t ...(1)

The value of x(t) can be obtained by integrating the expression for v(t) w.r.t. time, i.e. t as shown below :x(t) = (1/2).a.t² + u.t + x₀ = (1/2).32t² + 0 + 20ft = 16t² + 20ft ...(2)

Here, x₀ = 20ft is the initial displacement of the brick above the ground.

Now, we can answer the questions as follows:

(a) Using  the following relation: v = u + a.t = 0 when the brick is at its highest point.

Hence, the time taken to reach this point can be obtained as follows:0 = u + a.t ⇒ t = (-u/a) = (0/32) sec = 0 secThis means that the brick reaches its maximum height at t = 0 sec, which is the initial moment.

Thus, the maximum height reached by the brick above the ground is, x(0) = 16.0² + 20 = 20 ft

(b) The time taken by the brick to reach the ground can be obtained by using the following relation: x(t) = 0.

Here, we are interested in finding the value of t.

Hence, we can substitute x(t) from equation (2) above and equate it to 0 to obtain the value of t as shown below:16t² + 20 = 0 ⇒ t² = -(20/16) sec².

This means that the brick doesn't take any finite time to reach the ground from its maximum height.

This is because it falls vertically downwards from a height of 20 ft under the action of gravity.

Thus, it reaches the ground at t = 0 sec only.

(c) The speed of the brick just before it hits the ground can be obtained by using the expression for v(t) from equation (1) above and substituting t = 0 sec (just before it hits the ground) as shown below:

v(0) = 32(0) = 0 ft/sec.

Hence, the speed of the brick just before it hits the ground is 0 ft/sec.

The moment of inertia of a rotating object is the torque required for angular acceleration. Wheel A has three times the moment of inertia of wheel B, and their angular speed is four times that of wheel A. the value of KA/KB is 24

The moment of inertia of a rotating object represents the amount of torque that must be applied to it in order to produce an angular acceleration of a certain magnitude. According to the question, wheel A has three times the moment of inertia of wheel B about its axis of rotation.

Thus, the ratio of the moment of inertia of wheel A to that of wheel B is given by:Iₐ/Iₚ = 3/1 (1)Also, it is given that the angular speed of wheel B is four times that of wheel A. Since the rotational kinetic energy of a wheel is given by the expression KE = 1/2*I*w²,

the ratio of the rotational kinetic energies of wheels A and B, KA/KB, can be given by:

KA/KB = (1/2 * Ia * wa²) / (1/2 * Ib * wb²)

We substitute Equation (1) in the above equation to get:

KA/KB = (1/2 * 3 * Ib * 16) / (1/2 * Ib * 1)KA/KB

The height of the table is 1.225 m.

The acceleration an object experiences as a result of gravitational force is known as acceleration due to gravity. M/s² is its SI unit. Its vector nature—which includes both magnitude and direction. The unit g stands for gravitational acceleration. At sea level, the standard value of g on earth's surface is 9.8 m/s².

In the question, it is said that the coin lands 0.2 m away from the table horizontally and the coin has a speed of 0.4 m/s horizontally.

So, distance = speed × time

⇒ 0.2 = 0.4 × time

⇒ time = 0.5 s.

In vertical motion of coin, there acts only acceleration due to the gravity. So in time t= 0.5 s, the coin travels a height,

h = \(\frac{1}{2}\)gt²

The correct answer is d = 312.5 m.

These formulas are used to describe an object's linear motion. Positive acceleration is present if the thing accelerates.

The equations utilised are as follows:

v = u + at

d = ut + 0.5 at^2

v^2 = u^2 + 2 ad

initial velocity u = 25 m/s

acceleration a = - 1 m/s^2

V is equal to zero in the end.

Let d represent the distance covered.

Now, with the third motion equation,

v^2 = u^2 + 2ad
