How do you compare the mass of proton, neutron, and
electron?

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.

If a balloon is taken outside on a very cold day, what will occur?

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
