0.50kg ball is traveling to the right with a velocity of +10.0m/s. The ball collides elastically with a second ball, which has a mass of 1.5kg and is also traveling to the right with a speed of 4.0m/s. Calculate the final velocities of both balls, assuming a head - on collision.​

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

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)

The diagram shows a series of volcanic island and a hot spot determine the direction of movement of the tectonic plate that for the island
