Data:

Speed of light c =3.00 × 10⁸m/s

Gravitational constant G =6.67 × 10⁻¹¹N · m²kg²

Acceleration due to gravity g =9.80m/s²

Fundamental charge e =1.60× 10⁻¹⁹ C

Mass of electron me =9.11 × 10⁻³¹kg

Mass of proton mp =1.67 × 10⁻²⁷kg

Planck’s constant h = 6.63x10^-34 J·s

Coulomb’s constant 1/(4πε0) = 8.99x10⁹ N·m²/C²

Boltzmann constant k = 1.38x10^-23 J/K

Part A: Multiple Choice

1)A uniform meter stick is supported on a fulcrum at the 25­cm mark. A 0.50-kg object is hung from the 0-cm end of the meter stick, and the stick is balanced horizontally. The mass of the meter stick is:

1. 0.25 kg;
2. 0.50 kg;
3. 0.75 kg;
4. 0.75 kg;

2)The radius of the Earth is 6.37·10⁶m. Approximately how fast is a person on the Equator moving due to the Earth rotation?

1. 5 m/s
2. 50 m/s
3. 500 m/s
4. 5000 m/s

3)In a certain region of space, the electric field is zero. From this we can conclude that the electric potential in this region is:

1. constant;
2. zero;
3. positive;
4. negative;

4)A bullet of mass m and speed v hits a pendulum bob of mass M at time t1, and passes completely through the bob. The bullet emerges at time t2 with a speed of v/2. The pendulum bob is suspended by a stiff rod of length l and negligible mass. After the collision, the bob can barely swing through a complete vertical circle. At time t3, the bob reaches the highest position.

What quantities are conserved in this process?

1. Total kinetic energy of the bob and the bullet during the time interval Δt = t2– t1 .
2. Total momentum of the bob and the bullet during the time interval Δt = t2– t1 .
3. Total mechanical energy of the bob and the bullet during the time interval t3– t1
4. Momentum of the bob after t2

5)The diagram shows a circuit with four identical light bulbs.

When we remove bulb A from the circuit, the light intensity of bulb C:

1. remains the same;
2. increases;
3. decreases;
4. becomes zero.
