Two mirrors are at right angles to one another. A light ray is incident on the first at an angle of 30° with respect to the norm
al to the surface. What is the angle of reflection from the second surface?
1 answer:
Answer:
reflected angle - secod mirror = 60°
Explanation:
I attached an image with the solution to this problem below.
In the solution the reflection law, incident angle = reflected angle, is used. Furthermore some trigonometric relation is used.
You can notice in the image that the angle of reflection in the second mirror is 60°

Answer:
Acceleration
Explanation:
We have given that the force by the motor
Resistive force by the water
So net force
Mass of the boat = 1384.1 kg
According to newton's second law F=Ma, here M is mass and a is acceleration
So
