Consider the following experimenta group of students is doing an experiment to determine how the weight of an objecthung from a spring affects the length of the spring. the group used a 0.5cm diametersteel spring with an initial length of 10 cm. so what is the independent and dependent variable for this experiment (units)?

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 !
