Question
Approximately how far did the pole move per day?a. $<1 \mathrm{~m}$b. $\sim 16 \mathrm{~m}$c. $\sim 20 \mathrm{~m}$d. $\sim 12 \mathrm{~m}$
Step 1
The pole moved from 80°N to 84°N, which is a difference of 4 degrees. There are 111 kilometers per degree of latitude, so the pole moved 4 * 111 = 444 kilometers. Now, we need to find out how many days it took for the pole to move this distance. The pole moved Show more…

A person in a spaceship holds a meter stick parallel to the motion of the ship as it passes by the Earth with $\gamma=2 .$ What length does an observer at rest on the Earth measure for the meter stick? a) $2 \mathrm{~m}$ c) $0.5 \mathrm{~m}$ e) none of the above b) $1 \mathrm{~m}$ d) $0.0 \mathrm{~m}$
A meter stick moving at 0.900$c$ relative to the Earth's surface approaches an observer at rest with respect to the Earth’s surface. (a) What is the meter stick’s length as measured by the observer? (b) Qualitatively, how would the answer to part (a) change if the observer started running toward the meter stick?
