Aball is revolving horizontally in a circle of radius 1.8 m, and is held by a rigid, massless rod. the mass of the ball is 0.1 kg. the path of the ball has a constant linear speed of 27 m/s. what is the angular velocity of the orbit in rad/s?

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?

The radius of a sphere is increasing at a rate of 9 cm/ sec. find the radius of the sphere when the volume and the radius of the sphere are increasing at the same numerical rate.

The ph is the a.independent variable b.the dependent variable c.control group
