Agrindstone spinning at the rate of 8.3 rev's has what approximate angular speed? a. 3.2 rad/s b. 26 rad/s e. 52 rad/s d. 8t rad/s

52 rad/s

Explanation:

The rate at which the grindstone is spinning is 8.3 revolutions per second

This means that every second the grindstone completes 8.3 revolutions

A radian is basically the arc length of a circle.

Converting it to radians per second

8.3×2π = 16.6π = 52.15 radians per second

∴ Approximate angular speed is 52 radians per second

i cant see the choices man

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
