1. When a skydiver opens her parachute, she is falling with terminal velocity. What is the direction of the velocity and acceleration vector before she reaches the new terminal speed?

2. A sports car is accelerated from 0 to 120 km per hour in 4 s. What is the acceleration of the car?

3. In a flask, energy is transmitted to the water at a rate P. When the water approaches its boiling point, P is raised. What modifications have been made to the water's temperature and rate of evaporation since the change?

4. Which of the follow statements are true about total internal energy and total intermolecular potential energy of a solid substance when it undergoes sublimation to become a gas?

5. What is the phase difference between the displacement and acceleration of a particle executing simple harmonic motion (SHM)?

6. There is a flow of charge through a liquid. 0.15 C of negative ions and 0.15 C of positive ions move facing each other. What is the magnitude of the electric current flowing through the liquid?

7. A particle has a charge of ne. It is accelerated through a potential difference V. How is the work done of the particle calculated?

8. A proton traveling at velocity v enters a magnetic and electric field. There is no proton deflection. With a velocity of v, an electron and an alpha particle enter the same space. Which of the following statements are true with regards to the alpha and electron's paths?

9. A Neither alpha-particle will be deflected nor electron will be deflected because net force on both particles will be zero.

10. A beaker has 2 kg of water at room temperature. It is heated on a 450 W hot plate. The specific heat capacity of water is 4200 J kg–1 K–1. When the temperature of the water reaches a constant value, it is removed from the hot plate. What is the initial rate of change of temperature?

11. After a metallic surface is exposed to infrared radiation, photoelectrons are released from the same surface. The ultraviolet radiation has the same intensity as the infrared radiation. What will happen to the photoelectrons' kinetic energy and the pace at which they are ejected?

12. During gamma decay, photons of discrete energy are emitted. What does this mean?
