5. Calculate gravitational field strength (g) on the surface of Jupiter. (Mjupiter = 1.91 X 10 kg: radius=7.14 X 100) A 25 ms B. 9.8 m/s C. 16 m/s D. 32 m's

Which property of fossils allow scientists to determine the relative rock ages..

A500g object falls off a cliff and losers 100 j from its gravitational potential energy store. if the gravitational field strength g=9.8n/kg, how high is the cliff?

Can anybody me with this? ? (picture included.)
