Two objects, one of mass m and the other of mass 2m, are dropped from the top of a building. when they hit the ground two objects, one of mass and the other of mass 2, are dropped from the top of a building. when they hit the ground the heavier one will have twice the kinetic energy of the lighter one. the heavier one will have 2√ times the kinetic energy of the lighter one. both of them will have the same kinetic energy. the heavier one will have four times the kinetic energy of the lighter one

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
