An astronaut in the space shuttle is orbiting the earth at an altitude of 2.982 x 10^5 m. He sends a radio transmission to a receiving antenna directly below him on the earth. What is the time delay between the time he sends his signal and when the receiving antenna on the earth picks it up?

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
