Ava walked 3 blocks south, 5 blocks east, and then another 3 blocks south. Which diagram has the correct vectors for Ava's walk and her displacement ? Remember, the starting point of each part of the trip is the beginning of the arrow and the ending point is the pointed end of the arrow. (Sorry i couldn’t get all the answers in one picture, and won’t let you use more then one)

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 !
