1. A wire of resistance 5.0 ohm is connected to a battery whose emf is 2.0V and whose potential resistance is 1.0 ohm. In 2.0min, how much energy is (a) transferred from chemical form in the battery, (b) dissipated as thermal energy in the wire, and (c) dissipated as thermal energy in the battery?

2.The starting motor of a car is turning too slowly, and the mechanic has to decide whether to replace the motor, the cable, or the battery. The car's manual says that the 12V battery should have no more than 0.02 ohm internal resistance. The motor no more than 0.2 ohm resistance, and the cable no more than 0.04 ohm resistance.The mechanic turns on the motor and measures 11.4V across the batter, 3.0V across the cable, and a current of 50A. Which part is defective?

A capacitor C is charged from a 10V supply through a resistor, and is then fully discharged again so that its voltage cycles from 0 to 10V and back to 0. Find the energydissipated in the resistor, the energy stored in the capacitor, and energy drawn from the voltage source in this cycle.

The rms speed of the molecules in 1.9 g of hydrogen gas is 1800 m/s .

A block of mass M slides along a horizontal table with speed Vo. At x=0 it hits a spring constant k and begins to experience a frictional force. The coefficient of friction is a variable and is given by u=bx, where b is a constant. Find the loss in mechanical energy when the block has come momentarily to rest.

1. A controller on an electronic arcade game consists of a variable resistor connected across the plates of a 0.22 micro Farad capacitor. The capacitor is charged to 5.00V, then discharged through the resistor. The time for the potential difference across the plates to decrease to 0.800V is measured by a clock inside the game
