    The international space station (ISS) orbits the Earth with an approximately circular orbit 420 km above Earth's surface (6790 km above the center of the Earth). Suppose one evening the ISS passes in front of the full moon - which subtends an angle of 30 arc minutes (0.5 degrees)- in such a way that it exactly bisects the moon. How long will it take to cross in front of the Moon from one end to the other, as viewed by...

    2. Artificial gravity is necessary for humans to stay healthy during extended stays in space. To provide artificial gravity, a space station is shaped like a cylinder with a diameter of 2200 m, and it rotates about its center at a constant rate. The astronauts live inside the cylinder at the outer edge, and feel a gravitational pull outwards. (a) How long should one revolution of the space station take if the acceleration of an astronaut on the outer edge...
