You pull horizontally on a 50-kg crate with a force of 500 N and the friction force on the crate is 100 N. There is also air resistance of 20 N. What is the acceleration in the x direction of the crate?

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.

You charge a parallel-plate capacitor, remove it from the battery, and prevent the wires connected to the plates from touching each other. when you increase the plate separation, what happens to the following quantities?
