Figure 13-27 gives the gravitational acceleration a g for four planets as a function of the radial distance r from the center of the planet, starting at the surface of the planet (at radius R 1 *R 2 , R 3 or R 4 ). Plots 1 and 2 coincide for r ≥ R 2 plots 3 and 4 coincide for r ≥ R 4 . Rank the four planets according to (a) mass and (b) mass per unit volume, greatest first. Figure 13-27 Question 8.

Certain types of particle detectors can be used to reconstruct the tracks left by unstable, fast-moving sub-atomic particles. Assume
that a track with a length of L=2.97 mm in the laboratory frame of reference has been observed. Further assume that you
determined from other detector data that the particle moved at a speed of L=0.910 ⚫ c, also in the laboratory frame of reference. c
denotes the speed of light in vacuum. What proper lifetime would you determine for this particle from the data given?

While cruising down University Boulevard you are stopped by a cop who states that you ran a red traffic light. Because you don't
want to pay the stiff fine, you are attempting a physics defense. You claim that due to the relativistic Doppler effect, the red color of
the light λ=616 nm appeared green '=531 nm to you. The cop makes a quick calculation of his own and rejects your defense.
How fast, in terms of your speed u divided by the speed of light in vacuum c, would you have to drive to justify your claim? Note
that the speed u is taken to be a positive quantity.
