Question 1 1. Refer to the following diagram. If V = 220 volts, R1 = 12 ohms, and R2 = 20 ohms, what are the values of I1 and I2?

Question 2 2. A 1,000 kilogram mass is resting at equilibrium on an inclined surface that has an angle of 20 degrees above the horizontal axis. What is magnitude of the normal force on the mass?

Question 3 3. A raft having a total mass (weight plus passenger weight) of 150 kilograms is floating down a river at a constant speed of 25 meters/second when the river has a sudden 7 meter drop in elevation to discharge into a lake. Assuming that all frictional and drag forces are negligible, what is the velocity of the raft at the end of 7 meter elevation drop?

Question 4 4. 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 2 loops and has a current of 25 amps, what is the current in the secondary coil if it has 8 loops?

Question 5 5. One atom of the element Americium-241 undergoes a radioactive alpha decay. What is the molecular weight of the resulting atom?

Question 6 6. One photon of which of the following colors of visible light possesses the amount of highest energy?

Question 7 7. What type of variables are held constant by researchers during a scientific experiment?

Question 8 8. At what distance away from a 1 coulomb charge will an electrical field have a strength of 1,000 newtons per coulomb?

Question 9 9. A painter accidently drops his paint brush while he is on a scaffold painting a 20-meter tall building. His paint brush free falls vertically for 18 meters until it reaches the ground. What is the final velocity of the paint brush when it strikes the ground?

Question 10 10. How much force must a person apply to lift a 400 newton load using a moveable pulley system that consists of 3 support pulley sections?

Question 11 11. Which of the following types of electromagnetic waves has the greatest tendency to be diffracted?

Question 12 12. 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 27 centimeters and the focal length is 40 centimeters?

Question 13 13. What is the orbital velocity of the moon when it is 4.000 × 10^8 meters away from the Earth, given the mass of the Earth is 5.97219 × 10^24 kilograms and the radius of the semi-major axis of the moon's orbit is 3.844 × 10^8 meters?

Question 14 14. What is the buoyant force on a spherical ball with a diameter of 12 centimeters that is totally submerged in a swimming pool?

Question 15 15. A vertical spring-block oscillator with a spring constant k equal 800 newtons/meter has an angular velocity of 5 radians per second. What is the mass of the weight that is attached to the spring-block oscillator?
