A hollow spherical shell has mass 8.35 kg and radius 0.215 m. It is initially at rest and then rotates about a stationary axis that lies along a diameter with a constant acceleration of 0.910 rad/s2. What is the kinetic energy of the shell after it has turned through 5.25 rev?

Frost wedging occurs when water seeps into a crack in a rock, freezes, and causes the crack in the rock to widen. t or f

Why are graphs useful when interpreting data

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
