Answer:

Angle of incidence is equal to the angle of reflection.

Explanation:

Reflection is defined as the repropagation of light rays incident on a surface. An incident light is a light striking the surface of a plane mirror at an angle to the mirror. This incident light will reflect out at the same angle it strikes the plane. This angle is known as the angle of glance (g). The ray perpendicular to the plane surface is called the normal ray.

Therefore, the angle between the incident ray and the normal ray will be the angle of incidence (i) and the angle between the reflected ray and the normal ray will be the angle of reflection (r). Since the angle the incident ray made with the plane surface is equal to the angle that the reflected ray made with the plane surface then our angle of incidence will also be equal to the angle of reflection according to the second law of reflection i.e i=r.

i = r = 90°-g

A 20 N unbalanced force causes an object to accelerate at 1.5 m/s2. What is the mass of the object?

kicyunya [14]

As per Newton's II law we know that

$F = ma$

here we know that

$F = 20 N$

$a = 1.5 m/s^2$

now the mass of the object will be given as

$m = \frac{F}{a}$

$m = \frac{20}{1.5}$

$m = 13.3 kg$

so mass of the object will be 13.3 kg
