Actually Welcome to the Concept of the Rays of light.

Since we know that, The light ray on a shiny surface makes a angle with the normal, hence The Angle of incidence is equal to angle of reflection made with Normal Axis in the middle.

Thus Option c.) is correct.

C.) is the Answer.

The angle of reflection given the incident ray from the given diagrams is option C.

When a light ray strikes the shining surfaces, the part of the light gets refracted. The bouncing back of the light is called reflection. When the light strikes the surface is called an incident ray.

When the light ray incident on the surface, the light returns back to the same medium is called reflection. The laws of reflection are, the angle of incidence is equal to the angle of reflection, and the incident ray, reflected ray, and normal takes place in the same plane. The speed of light remains the same in the process of reflection.

The reflected light ray changes the path of direction in the same medium. When a light ray enters from one medium to another, the speed of light gets decreases.

Thus, the ideal solution is option C.

By Newton's second law, the net force on the car is

∑ F = m a

where m is the mass of the car and a is magnitude of the acceleration.

The car is slowing down, so the net force opposes the direction in which the car is moving. Vertically, the car is in equilibrium, the net force is entirely due to friction. Taking the direction opposite the car's motion to be negative, we have

- 200 N = (200 kg) (-a)

a = (200 kg) / (200 N)

a = 1 m/s²

If you're also supposed to find the coefficient of kinetic friction, use the fact that the car the vertical forces cancel out, namely

n + (-w) = 0

where n is the magnitude of the normal force and w is the car's weight. The friction force f is proportional to the normal force n by a factor of µ, the coefficient of kinetic friction, such that f = µ n. Then

f / µ = w

(200 N) / µ = (200 kg) (9.80 m/s²)

µ = (200 N) / ((200 kg) (9.80 m/s²))

µ ≈ 0.102

An action reaction pair of forces exists between : ( A ) The aerialist arms and legs

Action-reaction pair of force comprises of the force that acts on the object as a action force and the force experiened by the object due to newton third law of motion as the reaction force. Therefore in the diagram an action reaction pair of forces can be experienced between the aerialist arms and legs

Hence we can conclude that An action reaction pair of forces exists between : ( A ) The aerialist arms and legs.

Answer:

Explanation:

The weight of the crate will e equal to its normal reaction R

Since R = mgsin theta = W

W = mgsintheta ( resolved along the vertical perpendicular to the plank

Fy = 523sin22°

Fy = 195.92N

Since the weight is acting along the negative y direction,

Fy = -195.92N

The force parallel to the plank will be the force acting in the horizontal direction.

Fx = Fcos theta

Fx = 523cos 22°

Fx = 484.9N

Newton's 2nd law of motion:

Force = (mass) x (acceleration)

= (0.314 kg) x (164 m/s²)

=  51.5 newtons

(about 11.6 pounds).

Notice that the ball is only accelerating while it's in contact with the racket. The instant the ball loses contact with the racket, it stops accelerating, and sails off in a straight line at whatever speed it had when it left the strings.

Explanation:

The particles will have more space between them and will be moving at higher speeds as steam compare to water.

The quantity of heat (in joules or calories) per mole or unit mass of the substance undergoing a change in state is the typical way to represent latent heat.

The latent heat involved in melting solids or freezing liquids is referred to as the "heat of fusion," while the latent heat involved in vaporizing solids or liquids or condensing vapor is referred to as the "heat of vaporization."

When water boils at 100°C and turns into steam, water vaporizes into steam by absorbing heat of vaporization. This heat energy remains in the steam as kinetic energy and makes their movement fast.

So, The molecules will have more space between them and will be moving at higher speeds as steam compare to water.

Explanation:

because it's top speed is 50km/h,so it's initial speed may be less. when it covers some distance it's speed changes again. then we have given a mean speed .mean speed means sum of all speed divided by sum of total time.so the mean speed and final speed differs from each other

Answer:

As ice melts into water, kinetic energy is being added to the particles. This causes them to be 'excited' and they break the bonds that hold them together as a solid, resulting in a change of state: solid -> liquid.

Explanation:

As the ice melts into liquid water, the kinetic energy of the particles in the sample increase. The temperature of the sample is directly proportional to the kinetic energy of the particle.

The kinetic energy of an object is the energy which it possesses due to the motion of the object. Kinetic energy is defined as the work which is needed to accelerate a body of a given mass from the rest position to its stated velocity. The body of an object maintains the same amount of kinetic energy which it gained during its acceleration unless its speed changes.

The temperature is directly proportional to the kinetic energy of the object. As the temperature of the object increases the phase of the object changes from solid to liquid.
