11. Astronauts are on a spacecraft traveling at 2.7 x 108 m/s with respect to Earth. (a) Calculate ẞ and y for the relative motion of Earth and the spacecraft. (b) According to a biology text, it takes 45 s for blood to circulate around the human body. If astronauts on the spacecraft run experiments to determine how long (on their own clocks) it takes their blood to circulate around their bodies. What should they measure? Even if you aren't sure about a numerical answer to this question, you should at least be able to explain whether the time will be the same, shorter, or longer than 45s. (c) If Earth-bound scientists use remote equipment to measure how long it takes for the blood to circulate around the astronaut's bodies, how long will will it take according to clocks on Earth? Even if you aren't sure about a numerical answer to this question, you should at least be able to explain whether the time will be the same, shorter, or longer than 45 s.
