A car is driving at a velocity (v) of 15 m/s. If you were calculating the kinetic energy (KE) of the car, you would have to complete which of the following steps? * Multiply 15 m/s by 2
Divide 15 m/s by 0.5
Multiply 15 m/s by 15 m/s
Add 15 m/s to the PE of the car

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 !
