I would really appreciate it if someone could answer all of these, but just one would be very helpful!!!
1. The diagram shows 2 identical charged particles. How does the potential energy and the force of repulsion change as the charges are brought closer together?
2. For the positions labeled on the image, list in order from highest to lowest the potential energy of the roller coaster. How is the kinetic energy of the roller coaster related to these values?
3. Consider the motion and size of the two vehicles headed for each other on the road. Compare the kinetic energy of the vehicles.

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 !
