Place me with this question is my last question

What are chlorofluorocarbons and what impact do they have on the atmosphere?

The slope of a velocity time graph over any interval of time gives the during that interval

When you jump from an elevated position you usually bend your knees upon reaching the ground. by doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. in this way the average force your body experiences is a) less than 1/10 as great. b) more than 1/10 as great. c) about 1/10 as great.d) about 10 times as great.
