In the solar system, there are many small pieces of rocks (i.e., asteroids) floating around that we canactually detect and whose orbits we can track. We’ll learn more about these later, but for now let’stake a look at the orbits of the asteroids. You’ll want to keep 3-4 significant digits throughout this problemand report all periods in years.(a) Imagine here is a gap in semi-major axis near a hypothetical 2.502 AU. What would the orbital period be of asteroids at this location?(b) The explanation for the missing asteroids has to do with gravitational interactions from themassive planet Jupiter located at 5.204 AU. Calculate is the orbital period of Jupiter in years? This is ungraded problem that uses Kepler's 3rd law.

the up mIbi, thla 2. In the future, we may encounter a civilization from another planet. They will not use the SI or AE systems of units. Suppose we meet aliens who use the Zerf as a unit of mass and the Spund as a unit of force. One Spund is the weight of a mass of one Zerf on the surface of Mars. The gravitational acceleration on Mars is 3.7 m/s?. a.) What is gc in the alien system of units? Be sure to include the numerical value and the units. b.) How much would a 350 Zerf object weigh on the surface of Mars, in Spunds? c.) How much would a 350 Zerf object weigh on the surface of the Earth, in Spunds? d.) To which system of units is the Zerf-Spund system most similar, Sl or AE?
You are on the plane neptune and want to determine the acceleration due to gravity, g. You have a stopwatch and a toy gun that can launch a ping pong ball vertically upwards with an initial velocity of 7.5 m/s. Describe, in words, how you would perform an experiment to determine the acceleration due to gravity. Be sure to describe the variables you would measure, the equations you would use and the assumptions you would make. Make sure to include a diagram of the physical situation, label know and unknown quantities with units, coordinate system. Thanks!
