The answer is : We’ll see the bell move, but we won’t hear it ring. This is because light can travel through vacuum but sound cannot. Sound waves are vibrations of particles in any media, so sound requires a medium to travel, and it cannot travel in a vacuum as there is no particles to vibrate.
It will eventually wear down the rock due to hydraulic action and etc

Explanation:
From the question we are told that:
Diameter
Distance
Generally the equation for circumference of a circle is mathematically given by
Therefore
Angular distance that the pie plate has moved through in revolutions is
Generally Angular distance that the pie plate has moved through in radians is
Generally Angular distance that the pie plate has moved through in degrees is
protons and nuetrons are all attracted to each another as the result of the strong nuclear force
The kinetic energy of an object is given by:
where m is the mass of the object and v its speed. The ball in this problem has a mass of m=0.2 kg and a kinetic energy of K=40 J, so we can rearrange the previous equation to find its speed:
