3. Question 3 On a graph where the x axis is horizontal and the y axis is at an angle of 70 degrees to the x axis, what are the…
2. Question 2 On a spacetime diagram where we want to plot the world line for a light beam, why is it not useful to use units of meters for…
9. Question 9 Imagine that you had a spaceship that could travel at the speed of light. If you got in your spaceship and took a well-running clock (any clock…
4. Question 4 If 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…
2. Question 2 Consider a situation that is similar to that in one of the video lectures, i.e., Alice observing Bob traveling from Earth to a star at a certain…
6. Question 6 Imagine that Bob, at a spaceport, observes Alice flying by to the right in her spaceship at a velocity of 0.9c. When Alice’s ship had been previously…
5. Question 5 In the Lorentz transformation equation for time, what is a consequence of the xmoving term? 1 point Time dilation Leading clocks lag Length contraction
2. Question 2 Consider a situation that is similar to that in one of the video lectures, i.e., Alice observing Bob traveling from Earth to a star at a certain…
7. Question 7 True or false: “Leading clocks lag” is a consequence of the relativity of simultaneity. 1 point True False
3. Question 3 In deriving the Lorentz transformation equations, we started by considering an event (a flash) that occurred at some time tB and at the location xB = 0,…
