Abullet shot straight up returns to its starting point in 10 s. what is the initial speed of the bullet, assuming negligible air resistance?

Identify the arrows that show the correct direction of heat transfer. 66°f 112°f 98°f

Atelevision set that has been running for a while heats up even the air around it. which two laws of thermodynamics could be used to analyze this scenario

A14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
