Question 1

Question
A small magnet of mass 1 g is levitated by a piece of superconductor. What is the force the magnet exerts on the superconductor? (g = 10m/s^2)
Answer
  • 0 N
  • 0.001 N
  • 0.01 N
  • 1 N

Question 2

Question
A woman stands on a bathroom scale in an elevator which is not moving. The scale reads 500 N. The elevator then moves downward at a constant velocity of 5 m/s. What does the scale read while the elevator descends with constant velocity?
Answer
  • 100 N
  • 250 N
  • 450 N
  • 500 N

Question 3

Question
A point source of sound on top of a police car emits a signal at 1000 Hz. If the car is traveling in a straight line at 20.0 m/s, what is the perceived wavelength (to three significant figures) as measured by someone standing on the road directly in front of the car? Take the speed of sound to be 335 m/s.
Answer
  • 0.305 m
  • 0.203 m
  • 0.315 m
  • 0.355 m

Question 4

Question
Converging lenses can produce:
Answer
  • only upright images
  • only inverted images
  • both upright and inverted images depending on the distance of the object
  • both upright and inverted images simultaneously

Question 5

Question
10 kg of the isotope tritium, which has a half-life of 12.3 years, is produced at a reactor. Which of the following values, in kg, is closest to the mass of tritium that will remain after 30 years?
Answer
  • 7.5
  • 1.8
  • 0.9
  • 6.6

Question 6

Question
A thin lens with focal length f is to be used as a magnifying glass. Which of the following statements regarding this situation is true?
Answer
  • A converging lens must be used, and the object be placed at a distance greater than 2 from the lens
  • A diverging lens must be used, and the object be placed between f and 2f from the lens
  • A converging lens must be used and the object be placed at a distance less than f from the lens
  • A diverging lens must be used and the object be placed at any point other than the focal point

Question 7

Question
In general. doubling the amplitude of a wave:
Answer
  • doubles the frequency
  • halves the period
  • quadruples the energy
  • doubles the speed

Question 8

Question
Ocean waves with a wavelength of 120 m approach the shore at the rate of 8 per minute. What is their speed (to two significant figures)?
Answer
  • 8 m/s
  • 16 m/s
  • 24 m/s
  • 30 m/s

Question 9

Question
Check all that are true for an ideal stationary fluid.
Answer
  • The density increases linearly with depth
  • Only the fluid at the surface is in mechanical equilibrium
  • The fluid below the surface has a propensity toward the mechanical equilibrium
  • The pressure increases linearly with depth

Question 10

Question
A woman floats comfortably in a sitting position in a body of water. Her entire torso (above the belly button) is above the surface of the water. What does this situation tell you about the water?
Answer
  • It's not possible
  • The water has a dissolve addictive (such as salt) which makes it much more dense than fresh water
  • The temperature of the water is significantly higher than normal
  • The woman is wearing a hat made of buoyant material

Question 11

Question
Four identical bulbs are connected in parallel to a 12V ideal battery. Two of them burn out. The remaining two:
Answer
  • Look brighter than before
  • Look the same as before
  • Look dimmer than before
  • Are off

Question 12

Question
A hockey puck struck by a hockey stick is given an initial speed of 10 m/s. If the coefficient of friction between the ice and the puck is 0.1, how far will the puck slide?
Answer
  • 39 m
  • 45 m
  • 51 m
  • 57 m

Question 13

Question
Ying and Albert are carrying Faisal on a horizontal stretcher. The stretcher is uniform, is 2.0 m long, and weighs 100N. Faisal weighs 800N. Faisal's centre of gravity is 75 cm from Ying. Ying and Albert are at the ends of the stretcher. The force that Albert is exerting to support the stretcher with Faisal on it is:
Answer
