Gravity is the force by which a planet or other body draws objects toward its center.
The force of gravity keeps all of the planers in orbit around the Sun. What does the
force of gravity depend on? *
A)mass and weight B)weight and speed C)mass and distance D)speed and distance

The force of gravity depends on mass and distance.

The frequency is 180 revolutions per minute or rpm. In physics, we can find the tangential speed of the hands using the formula:

v = rω,
where v is the speed, r is the radius of the circle and ω is the frequency

v = (140 cm/2)(180 rev/min)(1 min/60 s)
v = 210 cm/s
