A 7kg bowling ball is at rest at the end of a bowling lane. You push the ball with a force of 22N which induces a - 1N of friction force so the ball

accelerates 3m/s/s. What is the net force acting on the ball?

IE is the energy required to remove an electron from an atom. As atomic radius increases, the valence electrons get farther from the nucleus. How do you think an atom's size will affect its ability to hold on to its valence electrons? Why?

When an electric current flows through a long conductor, each free electron moves a. through a relatively short distance. b. from one end of the conductor to the other end. c. back and forth between the ends of the conductor. d.
