"Why Microwave is used to communicate in artificial satelites though Radio wave has larger wave length (can travel long distance as compare to microwave)?"

Drag each item into the proper state of matter category.

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
