The discovery of the electron as a subatomic particle was a result of

3. a lunar exploration vehicle was created by a research team. it weighs 3,000 kg on the earth. it needs an acceleration of 10 m/s2 on the moon. in order to have the same acceleration, what will be the net force acting on the vehicle on the earth?

Convection occurs when thermal energy is transferred by the movement of
