Alculate the potential difference if 20J of energy are transferred by 8C of charge.

An object moves from position +34m to the position -15m in 15 seconds. what is the total displacement? what is the total velocity?

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)

The strong nuclear force acts over a small distance than the electrostatic force. true or false
