Suppose you pour a gallon of water on a yowling cat 10 ft below your bedroom window. How much potential energy ( ft ⋅ l b f ) (ft·lbf) does the water lose? How fast is the water traveling (ft/s) just before impact? True or false: Energy must be conserved, therefore the kinetic energy of the water before impact must equal the kinetic energy of the cat after impact. If you decide the answer is false, what happens to most of the kinetic energy that the water possessed just before impact?

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
