1. What happens to the image formed by a concave mirror as the object is moved from far away to near the focal point?

2.

The diagram above (not drawn to scale) gives the first few electron energy levels within a single-electron atom. Which of the following gives the energy of a photon that could NOT be emitted by this atom during an electron transition?

3. During an isothermal expansion, a confined ideal gas does 150 J of work against its surroundings. Which of the following describes the heat transfer during this process?

4.

The figure above shows the equipotential lines a positive charge Q moves through. Along which path is the most work done on the charge?

5. An object of volume 2 × 10-3 m3 and weight 6 N is placed into a tank of water, where it floats. What percentage of the object's volume is above the surface of the water?

6.

The figure above shows two positively charged particles. The +Q charge is fixed in position, and the +Q charge is brought close to +Q and released from rest. Which of the following graphs best depicts the acceleration of the +Q charge as a function of its distance Q from +Q ?

7. Each of the following particles is projected with the same speed into a uniform magnetic field B such that the particle's initial velocity is perpendicular to B. Which one would move in a circular path with the largest radius?

8.

Which statement correctly characterizes the work done on the gas during the ABCA cycle shown in the above P-V diagram?

9. How much current does a 60 W light bulb draw if it operates at a voltage of 120 V ?

10. Question below refers to the following plane diagram. The figure shows four point charges arranged at the corners of a square with point B as its center.
