Acyclist allows his bike to roll down a hill without pedaling . towards the bottom of the hill he applies his brakes. the bike comes to a stop. applying the brakes causes the brakes to warm up. describe the energy transfers that have occurred. state the forces doing work that couses each these energy transfers . you can ignore any friction between the bike and the ground and any air resistance.

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 !
