Acar moves horizontally with a constant acceleration of 3 m/s2. a ball is suspended by astring from the ceiling of the car. the ball does not swing, being at rest with respect to thecar. what angle does the string make with the vertical?

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 !
