Ответ:
C) 4.0 m/s²
Explanation:
Centripetal acceleration can be found by the formula
a = v²/rWe are given the velocity of the car, 4.0 m/s.
We are also given the radius of the circular track, 4.0 m.
Substitute these values into the formula.
a = (4.0)²/4.0 a = 16.0/4.0 a = 4.0The magnitude of each car's centripetal acceleration is C) 4.0 m/s².

The sun does not have a solid surface, but the gases of the photosphere are thick enough to be visible. When you look at a typical image of the sun, you are looking at the photosphere. It is considered to be the sun's surface layer.
