Part A: Multiple Choice

1)Consider the electric power dissipation due to resis­tance in a circuit. Which of the following changes leave the dissipated electric power unchanged?

1. Doubling the voltage and reducing the current by a factor of two.
2. Doubling the voltage and increasing the resistance by a factor of four.
3. Doubling the current and reducing the resistanceby a factor of four.
4. None of the above.
5. Both(b) and(c) are correct.
6. (a),(b) and(c) are correct.

2)A U-shaped glass tube closed at both ends and posi­tioned vertically is partly filled with water. At a cer­tain time the levels of water are different in the two arms of the tube due to a difference in air pressure above each arm.
