The angular momentum of an electron in each of its orbits must be some multiple of:
wavelength
planck's constant
velocity of light
circumference

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.

Astate of matter all that has define volume and can flow is a(n)

What’s #16 asking and how do i solve it?
