Abox with a mass of 12.5kg sits on the floor how high would you need to lift it has a gpe of 568j

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.

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f

Does the asteroid belt revolve around the sun?
