Question

1) Use e_c= (T_H– T_C)/T_Hwhere T_His hot temperature (in the Kelvin scale, K) and T_cis the cold. If T_H= 700 K and T_C= 300 K, what is the efficiency e_C(Number less than 1, no units)?

2) The electric potential (voltage) is the amount of work in joules require to move one coulomb (C) of charge. How much work is required to move 2 C through 12 V of potential? (only number, no units)

3) What is the force between two charged spheres that are 0.5 m apart one with 6 µC of charge and other 9 µC of charge? (no units, just number)

4) Three 100 ohms resistors are in series attached to a 24 V power source. What is the current flowing through the circuit? (Just number, no units)
