How many hours does it take for the ISS to make each orbit? (Express your answer to three significant figures.) 2) Some of the experiments performed by astronauts in the ISS involve the effects of "weightlessness" on objects. What gravitational force does Earth exert on a 12.0-kg object in the ISS? Express your answer in newtons. (Express your answer to three significant figures.) 3)
The International Space Station (ISS) orbits Earth in a nearly circular orbit that is 345 km above Earth's surface.
