The mass of jupiter is 300 times the mass of the earth. jupiter orbits the sun with tjupiter = 11.9 yr in an orbit with rjupiter = 5.2 rearth. suppose the earth could be moved to the distance of jupiter and placed in a circular orbit around the sun. which of the following describes the earth's new period? explain
a) 1 yr
b) between 1 yr and 11.9 yr
c) 11.9 yr
d) more than 11.9 yr
e) it would depend on the earth's speed.
f) it's impossible for a planet of earth's mass to orbit at the distance of jupiter.

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

Your starship, the aimless wanderer, lands on the mysterious planet mongo. as chief scientist-engineer, you make the following measurements: a 2.50-kg stone thrown upward from the ground at 14.0 m/s returns to the ground in 5.70 s ; the circumference of mongo at the equator is 2.20×10^5 km ; and there is no appreciable atmosphere on mongo. (a) the starship commander, captain confusion, asks for the following information: what is the mass of mongo? (b) if the aimless wanderer goes into a circular orbit 2.20×10^4 km above the surface of mongo, how many hours will it take the ship to complete one orbit? (c) an unmanned spacecraft is in a circular orbit around the moon, observing the lunar surface from an altitude of 44.0 km . to the dismay of scientists on earth, an electrical fault causes an on-board thruster to fire, decreasing the speed of the spacecraft by 23.0 m/s . if nothing is done to correct its orbit, with what speed (in km/h) will the spacecraft crash into the lunar surface?

A1500 w electric heater is plugged into the outlet of a 120 v circuit that has a 20 a circuit breaker. you plug an electric hair dryer into the same outlet. the hair dryer has power settings of 600 w, 900 w , 1200 w, and 1500 w. you start with the hair dryer on the 600 w setting and increase the power setting until the circuit breaker trips. under what setting does the circuit breaker trip.
