部分真题预览：

1）An insulated container with a divider in the middle contains two separated gases. Gas 1 is initially at a higher temperature than gas 2. The divider is then removed. Which of the following observations might be made over a period of time as the two gases mix together, and why?

1. Gas 1 remains at a higher temperature than gas 2 because gas 1 started at a higher temperature.
2. Gas 1 remains at a higher temperature than gas 2 because gas 1 started with a higher kinetic energy.
3. On average, the molecules of gas 1 lose all of their kinetic energy to the molecules of gas 2 through collisions, resulting in gas 2 eventually having a higher temperature than gas 1.
4. On average, the molecules of gas 1 lose some of their kinetic energy to the molecules of gas 2 through collisions, resulting in the two gases eventually having the same temperature.

16）A typical iron nucleus contains 30 neutrons and 26 protons. Which of the following explains why the nucleus stays together despite the electric repulsion between the protons?

1. The neutrons become polarized and exert a net attractive electric force on each proton that is stronger than the net repulsive force.
2. The net gravitational force exerted on each proton due to all the nucleons is stronger than the net repulsive force.
3. The net magnetic force exerted on each proton due to all the nucleons is stronger than the net repulsive force.
4. The net strong force on each proton due to all the nucleons is stronger than the net repulsive force.

22）A student is given a loudspeaker with a square opening and asked to make a change in the dimensions of the opening so that the sound wave is more spread out vertically and narrowed horizontally. Which of the following is the correct use of the principle of diffraction to accomplish the desired result?

1. The task is impossible since diffraction affects only electromagnetic radiation and very short wavelengths.
2. Make the opening into a rectangle with a longer vertical dimension and a shorter horizontal dimension.
3. Make the opening into a rectangle with a longer horizontal dimension and a shorter vertical dimension.
4. Keep the opening in the shape of a square, but reduce both the horizontal and vertical dimensions.
