1. When a 1.2 kN resistor and a 100 Q resistor are connected in parallel, the total resistance is a) greater than 1.2N c) less than 1002 but greater than 902 d) less than 902 b) greater than 100 N but less than 1.22

A proton and an electron are in a constant electric field created by oppositely charged plates. The proton is released from the positively charged side and the electron is released from the negatively charged side. When they strike the opposite plates, which one has more kinetic energy (KE)? a) proton b) electron c) both acquire the same KE d) neither – there is no change of KE
