The electric potential a distance r from a small charge is proportional to what power of the distance from the charge?

(a) r^-1
(b) r
(c) r^-2
(d) r^2

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 !

You can decrease the resistance of a length of wire by

The solid that is formed and usually sinks to the bottom of a solution is the
