1. Two atomic clocks are synchronized. One is placed on a satellite, which orbits around the earth at high speed for a whole year. The other is placed in a lab and remains at rest, with respect to the earth. You may assume that both clocks can measure time accurately to many significant digits. a. Will the two clocks still be synchronized after one year? Explain your reasoning. b. Imagine that the speed of light was much slower than its actual value. How would the results of this experiment change if the speed of light was only twice the average speed of the satellite? Explain your reasoning, using a calculation.

It is year 2120 and we have figure out a propulsion system that allows spaceships travel at velocities as high as v = 0.87c. A first expedition to Alpha Centauri (the nearest planetary system) is being planned. Alpha Centauri is 4.3 ly away. Answer the following 5 questions below asking you about the details of this expedition. Question 10 Assuming a constant velocity of v=0.87c, how long would the trip to Alpha Centauri take as observed by the ground control team here on Earth? Give your answer in years

a) Suppose you decide to travel to a star 66 light-years away at a speed that tells you the distance is only 24 light-years. How many years would it take you to make the trip? Express your answer using two significant figures. b)In its own reference frame, a box has the shape of a cube 1.5 mm on a side. This box is loaded onto the flat floor of a spaceship and the spaceship then flies past us with a horizontal speed of 0.90 cc.What is the volume (m3 ) of the box as we observe it?
