- Mercury takes 88 days to complete an orbit around the Sun; Venus takes 225 to complete an orbit around the Sun. Which of the following might be the period of a Hohmann transfer orbit that takes you from Mercury to Venus? Question 21 options: 225 days 44 days 88 days 450 days 140 daysCalculate the escape velocity to an orbit of 457 km height from a planet with the radius of 2000 km and the density of 3400 kg⋅m-³. Give your answer in Sl units.Two large asteroids start with an initial separation of r0, at which time they each exert a gravitational force on the other of strength F0. After they have fallen toward each other for a period of time, their separation has decreased to 0.38r0. At that moment, what is the strength of the new gravitational force that each asteroid feels, in terms of F0? Blank 1. Calculate the answer by read surrounding text. times F0. Express your final answer to at least 3 significant figures.
- Please asapA synchronous satellite, which always remains above the same point on a planet's equator, is put in orbit around Jupiter so that scientists can study a surface feature.
