Question 1 1. A primary current carrying coil and a secondary coil are located within a mutual magnetic field inside of a transformer. If the primary coil contains 3 loops and has a current of 30 amps, what is the current in the secondary coil if it has 5 loops?

Question 2 2. What is the quantity and type of electrostatic force that occurs when two protons are located 5 nanometers apart? Note that the electrostatic charge of 1 proton = 1.602 × 10^-19 coulombs.

Question 3 3. Light rays from the air shinning into a basin of an unknown liquid material have a refraction angle from the normal line (θ R) of 33 degrees. If the light rays in the air have an incidence angle (θ I) of 45 degrees from the normal line, what is the refractive index of the unknown liquid, assuming that air has a refractive index of 1.0?

Question 4 4. What is the image distance and characterization (i.e. real or virtual) of a reflected image from a convex mirror if the centerline distance from the object to the mirror is 45 centimeters and the focal length is 30 centimeters?

Question 5 5. Refer to the following diagram. If V = 220 volts, R1 = 25 ohms, and R2 = 35 ohms, what are the values of I1 and I2?

Question 6 6. A simple pendulum is oscillating at a frequency of 0.33 hertz. What is the length of the string that is attached to its weight?

Question 7 7. If a neutron (mass = 1.675 × 10^-27 kilograms) is emitted from a nuclear fission reaction at a velocity of 4.2 × 10^7 meters per second, what is its de-Broglie wavelength?

Question 8 8. The drain line for a swimming pool has a diameter of 20 centimeters at the bottom of the pool and later reduces to a diameter of 16 centimeters at the point where the line connects to a sanitary sewer located a vertical distance 4 meters below the bottom of the pool. If fluid velocity in the drain line is 9 meters per second at the bottom of the pool, what is the fluid velocity in the drain line at the junction with the sanitary sewer?

Question 9 9. A man with a mass of 80 kilograms jumps off a bluff that is located 4 meters above a lake. Assuming that the frictional and drag forces are negligible, what is the man's final velocity when he lands in the lake?

Question 10 10. One atom of the element Carbon-14 undergoes a radioactive beta decay. What is the elemental identity of the transformed atom?

Question 11 11. A 1,500 kilogram mass is resting at equilibrium on an inclined surface that has an angle of 33 degrees above the horizontal axis. What is the magnitude of the normal force on the mass?

Question 12 12. A rotating fan blade moves at a constant rate of 500 revolutions per minute when it operates at its low-speed setting and a rate of 800 revolutions per minute at its high-speed setting. It takes 4 seconds for the fan blade's speed to change from its low setting to its high setting. What is the fan blade's angular acceleration when its speed setting is changed from low to high?

Question 13 13. 80 newton-meters of torque is needed to open a ball-valve on a chemical feed pipe. How much force must be applied to open the valve if its handle is 8 centimeters long?

Question 14 14. Which type of electromagnetic waves are used to study the molecular structures of crystalline solids?

Question 15 15. Two collections of electrons with the same charge density but with different amounts of charge will _____.
