Suppose planet A is exactly twice the size (in surface area) of planet B. If both planets have the same exact surface temperature (1500 K), which planet would be releasing more power per unit area? Which planet would be releasing more total power? Group of answer choices planet B; planet A the planets would be releasing the same power per unit area; planet A the planets would be releasing the same power per unit area; planet B planet A; planet B

When large communications satellites are positioned in geosynchronous orbit (GEO), they are first launched into low-Earth orbit (LEO) while mated to a transfer stage. A transfer stage is a rocket specifically designed to move (or transfer) satellites from LEO  to GEO. Compare the amount of energy it requires to transfer a 8,000 kg satellite from a 750 km altitude orbit to GEO with the amount of energy required to send a 8,000 kg spacecraft from the same LEO orbit to the Moon so that it can land on the surface of the Moon. Note that the Lunar spacecraft will need the same orbital speed as that of the Moon around the Earth so that the Moon doesn’t move away from the spacecraft before it has a chance to land.

The incoming solar energy for the planet is 245 W/m2. What is the outgoing energy from the surface (arrow c)?
