The wheel spins as long as the hamster keeps running

Explanation:

The motion of a rigid body which takes place in such a way that all of its pieces move in circles about an axis with a fixed angular velocity; also, the rotation of a particle about a fixed point in space. When a torque (rotational analog of force) is connected to a body (system of particles) about an axis, it provides a twist and this provides rotational motion.

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)
