The masses of the blocks are m1 = 16.0 kg and m2 = 12.0 kg, the mass of the pulley is m = 5.00 kg, and the radius of the pulley is r = 0.300 m. block m2 is initially on the floor, and block m1 is initially 4.60 m above the floor when it is released from rest. the pulley's axis has negligible friction. the mass of the string is small enough to be ignored, and the string does not slip on the pulley, nor does it stretch. a/how much time (in s) does it take block m1 to hit the floor after being released? b/how would your answer to part (a) change if the mass of the pulley were neglected? (enter the time, in seconds, it takes block m1 to hit the floor if the mass of the pulley were neglected.)

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !

Light traveling in water, nwater = 1.33, strikes a plastic block at an angle of incidence of 51.4°; part of the beam is reflected and part is refracted. if the index of refraction of the plastic is 2.0, what is the angle made by the reflected and refracted beams?
