a light ray approaches a measure at an angle 22 degrees with the mirror surface. what is the angle of reflection of this light ray?​

Note: Angle of reflection is the angle the ray makes with the Normal of the Mirror and NOT the Mirror Surface

Since the ray makes an angle of 22° with the Mirror surface

The angle it'll make with the Normal is 90-22(Because both are orthogonal)

So

Angle of Incidence = 90-22 = 68°

From the Law of Reflection

Angle of Incidence = Angle of Reflection

So

Angle of reflection = 68°

Explanation:

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.

i think the answer is a and b

i wish you luck
