1. Two identical charges, each 4.79x10^-5 coulombs are separated by 0.36 meters. What is the force of repulsion between the charges in newtons? Express your answer in Scientific Notation.
2. Find the attractive force (in newtons) between a 7.99x10^-5 coulomb point charge and a -5.63x10^-5 coulomb point charge that are separated by 0.43 meters.
3. A heating element with a resistance of 11.07 ohms operates on 92.48 volts. What current (in amps) does it draw? Round your final answer to the two decimal places.
4. A small heater operates on 929.41 volts. If it draws 81.57 amps, find its resistance (in ohms). Round your final answer to two decimal places.
5. In the below there is a 2.70 volts battery and three resistors with the following values: R₁ = 9.57 ohms, R₂ = 9.04 ohms, and R₃ = 4.97 ohms. Find the equivalent resistance (in ohms) for this circuit.
