Question 8 (1 point) A metre stick is thrown past you at a speed of 0.50c in a direction along its length. From your frame of reference the stick appears to be what length? less than 1.0 m but more than 0.50 m long less than 0.50 m but more than 0 m long 1.00 m long exactly 0.50 m longQuestion 6 (1 point) When must special relativity be taken into account? for cars driving on a superhighway when hosting a long track speed skating event for aircraft flying near the speed of sound O when operating a particle accelerator Question 7 (1 point) - B - C E -) Points A. B, C, D, and E are evenly spaced, in order, along a line. A is set moving away from B at a constant velocity, and E is set moving away from D at a constant velocity. Both remain on the original straight line. Lights at B and D are turned on simultaneously as determined by an observer at C. Which statement is true? An observer moving with A will see B light up before D An observer moving with E will see D light up before B Both of the above statements are true Observers A, C and E, will see B and D light up simultaneouslyQuestion 1 (1 point) Mr. Smith is holding a tennis ball directly in front of him while standing in a railroad car moving east at 80 km/h when he tosses the ball with an initial velocity of 12 km/h [up] relative to the car. When the ball comes back down, where will it land, relative to Mr. Smith? directly in front of him north of him east of him west of him Question 2 (1 point) An airline passenger is walking on a moving sidewalk at 1.50 m/s [E] relative to the sidewalk. The sidewalk is moving at 1.80 m/s [E] relative to the airport terminal. He tosses a ball backward toward a friend standing on the sidewalk behind him at a speed of 1.30 m/s relative to himself. Determine the velocity of the ball relative to the airport terminal. ( 3.30 m/s [E] 2.00 m/s [E] 1.00 m/s [W] 1.60 m/s [E]Question 3 (1 point) Why may we consider the surface of Earth to be an inertial frame of reference? The accelerations due to planetary motion are very small Earth is at rest with respect to the Sun All answers are correct The solar system is at rest with respect to the galaxy Question 4 (1 point) You are observer A and you are holding clock A. Observer B passes you, holding clock B and moving at 0.90c. Select the best statement from the options below You see clock A running normally and clock B running slowly Observer B sees clock B running normally, but clock A running slowly C You see clock B running slowly, and observer B sees clock A running faster than normal Both the first and second are true Question 5 (1 point) Einstein's theory of relativity was readily accepted by physicists in 1905 because the technology to test the theory was available. True False
