If Galileo's experiment did not measure the speed of light, what did it measure? a) the speed of light using large distances
b)measured reaction time
c)the accurate measure of the speed of light in the air
d)calculated the speed of light over a short distance

How are calculation for velocity and speed different

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f

This is the number of complete movements of a wave per second.
