Aweather balloon is filled with helium that occupies a volume of 5.00 × 104 l at 0.995 atm and 32.0°c. after it is released, it rises to a location where the pressure is 0.720 atm and the temperature is -12.0°c. what is the volume of the balloon at the new location?

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
