Question 1 1. If an orange luminescent comet in outer space is able to move at a velocity faster than the speed of light (due to a cosmic explosion) away from an observer who is located on a nearby planet, which color would the observer most likely view emanating from the comet?

Question 2 2. If white light is shone normal through a single slit whose opening is 470 nanometers wide, what color of the visible light spectrum is least likely to exhibit diffraction as it passes through the slit?

Question 3 3. Which of the following sampling techniques would be the most efficient method to utilize to obtain data to support the hypothesis ''In the Eastern United States, trees with heights greater than 50 feet tall are normally an oak species?''

Question 4 4. One atom of the element Bismuth-209 (atomic mass = 208.9803987 atomic mass units) undergoes a radioactive decay reaction to form one thallium-205 atom (atomic mass = 204.9744275 atomic mass units) and one alpha particle (atomic mass of 4.001506 atomic mass units). What quantity of energy is converted from this mass loss?

Question 5 5. A vertical spring-block oscillator with a spring constant k equal to 940 newtons/meter has an angular velocity of 1.5 radians per second. What is the mass of the weight that is attached to the spring-block oscillator?

Question 6 6. What is the de Broglie wavelength of an alpha particle (mass = 6.68 × 10^-27 kilograms) that is emitted from a beta decay reaction at a velocity of 2.6 × 10^7 meters per second?

Question 7 7. What is the focal length of a convex thin lens if the object being viewed has a centerline distance that is 81 centimeters in front of the lens and its image appears at a centerline distance of 5.2 centimeters behind the lens?

Question 8 8. What is the quantity and type of electrostatic force that occurs if one proton and one electron are located 0.003 nanometers apart? Note that the electrostatic charge of 1 proton = +1.602 × 10^-19 coulombs and the electrostatic charge of 1 electron = -1.602 × 10^-19 coulombs.

Question 9 9. An experimental model predicts that a launched rocket will attain a maximum height of 558 meters. When the actual rocket was launched, it reached a maximum height of 579 meters. What was the percent error of the experimental model's prediction?

Question 10 10. A missile with a mass of 8 kilograms is fired from a ground-level launcher that is aimed at an angle of 41 degrees above the horizontal axis. If the initial velocity of the missile is 400 meters/second, what horizontal distance will the missile travel after 10 seconds?

Question 11 11. What is the gravitational force between the moon (mass = 7.35 × 10^22 kilograms) and a space shuttle with a mass of 2.03 × 10^6 kilograms that is orbiting it if the radius of the shuttle's orbit is 2,000 kilometers?

Question 12 12. Refer to the following diagram. If V = 240 volts, I1 = 10 amps, and I2 = 6 amps, what are the values of R1 and R2?

Question 13 13. A primary current carrying coil and a secondary coil are located within a mutual magnetic field inside of a transformer. If the primary coil has a voltage of 240 volts and contains 2 loops, what is the induced voltage in the secondary coil if it has 12 loops?

Question 14 14. A man is pushing a wheelbarrow with a total mass of 32 kilograms up a hill that is at an angle of 35 degrees above the horizontal axis. What force is the man applying to the wheelbarrow if it is moving at a constant acceleration of 0.08 meters/second up the hill and the frictional force opposing its motion is 50 newtons?

Question 15 15. A plastic horse with a mass of 22 kilograms is a figure on a merry-go-round that is rotating at a constant angular velocity of 1.3 radians per second. If the horse is located 15 meters away from the center of the merry-go-round, what is the centripetal force on the horse?
