A 35 kg solid sphere with a radius of 0.400 m is rotating at a frequency of 0.5 Hz about an axis of rotation that passes through its center. Determine the rotational kinetic energy of the sphere.

d is the answer i came up with

scientific laws are the result of testing theories and proving them to be facts.

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
