The first law of thermodynamics? A. whenever there is an opportunity for energy dispersal, the energy always spreads out

B. change in thermal energy (AU) of an object is equal to the heat (Q) that is added to the object minus the work (W) done by the object. O

The diagram shows a series of volcanic island and a hot spot determine the direction of movement of the tectonic plate that for the island

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
