NEED HELP please.

Physics
1 answer:
WARRIOR [948]3 years ago
5 0

Answer:

1. 23°

2. 65°

Explanation:

1.

The law of reflection provides that for the same medium, the angle of reflection equals the angle of incidence.

Similarly, here, angle of incidence and reflection will be 46°÷2=23°

2. Since the normal, angles of reflection and incidence lie on the same plane and also the angles of reflection and incidence are equal then the angle between the plane of the mirror and the reflected beam will be given by 90-25=65°

In comparison with a steep slope, a gentle slope _____.
kifflom [539]

A gentle slope requires less force over a longer distance as compared to steep slope.

Explanation:

Mechanical advantage of a slope is equal to the ratio of length of slope and the height. A steep slope has shorter length as compared to a gentle slope for the same height. Therefore, mechanical advantage of a gentle slope is more than that of a steep slope. Hence, a gentle slope requires less force over a long distance than a steep slope.

What is Newton's Second Law?
Rudiy27

Answer:

An object's acceleration depends on its mass and on the net force acting on it.

Explanation:

Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.
