4. suppose the observed motion of a moving airplane, illustrated by a distance vs. time graph, is nearly a straight line with zero distance traveled at zero time. state what this shows about the relationship between distance and time, name the type of relationship, and tell what it indicates about the speed of the airplane.

What are atoms of the same element with varying number of neutrons

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 !
