5.Question 5In the Lorentz transformation equation for time, what is a consequence of the xmoving term?1 pointTime dilationLeading clocks lagLength contraction

2.Question 2The effect of length contraction of a moving object arises from (check all that are correct):1 pointThe compression effect of moving through the etherThe lack of synchronization of a set of uniformly moving clocks, which are otherwise synchronized in their rest frame of reference"Leading clocks lag"The relativity of simultaneity

4.Question 4If v = 0 in the Lorentz transformation equation (and Alice is in one frame of reference and Bob in the other frame of reference), and Bob observes an event that occurs at x = 36 in his frame of reference, which of the following statements is true?1 pointAlice will observe the event at x = 18 in her frame of reference.Alice will observe the event at x = 72 in her frame of reference.We need to know the value of the Lorentz factor before we can know where Alice observes the event to occur.Alice will observe the event at x = 36 in her frame of reference.

9.Question 9Consider two identical light clocks, designed as explained in lecture. Bob has one, and Alice takes the other on her spaceship and flies by Bob at speed V. Bob observes Alice’s clock. What is the relationship between a certain amount of elapsed time on Bob’s clock and the corresponding elapsed time on Alice’s clock, as observed by Bob (where γ represents the Lorentz factor)? 1 pointThe elapsed time on Alice’s clock = γ times the elapsed time on Bob’s clock.The elapsed time on Alice’s clock = (1/γ) times the elapsed time on Bob’s clock.The elapsed time on Alice’s clock = the elapsed time on Bob’s clock.

9.Question 9Consider two identical light clocks, designed as explained in lecture. Bob has one, and Alice takes the other on her spaceship and flies by Bob at speed V. Bob observes Alice’s clock. What is the relationship between the duration of one tick on Bob’s clock and the duration of one tick on Alice’s clock, according to Bob (where γ represents the Lorentz factor)? (Tip: Think about the light clock diagram and the value of the Lorentz factor.)1 pointThe duration of one tick on Alice’s clock = (1/γ) times the duration of one tick on Bob’s clock.The duration of one tick on Alice’s clock = the duration of one tick on Bob’s clock.The duration of one tick on Alice’s clock = γ times the duration of one tick on Bob’s clock.

3.Question 3Consider the twin paradox example done in lecture: On Alice's return trip from the star back to Bob, Bob observes Alice's clocks running slower than his clocks. What does Alice observe regarding Bob's clocks?1 pointAlice observes Bob's clocks running slower than her clocks.Alice observes Bob's clocks running at the same rate as her clocks.Alice observes Bob's clocks running faster than her clocks.
