2. A 7.0 kg box, which is initially at rest at the bottom of a frictionless ramp, is pulled up the ramp by a string When it reaches a height of 2.0 m, the box is moving at 6.0 m/s. It takes 2.0 seconds for the box to reach this height.
a) Calculate the work done by the string in pulling the box
up
the
ramp.
b) Calculate the power exerted by the string in pulling the box up the ramp.

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 !
