Help Wanted ~ 50 Points! A diver jumps up off the 10 meter tower and spends 1.63 seconds in the air. How fast was she going when her feet left the diving tower? How fast is she going just before she hits the water?
The diver has a speed of as she leaves the tower.
The diver has a speed of just before she hits the water.

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)

The amount of heat required to change liquid water to vapor at its boiling temperature is 2256 kj/kg. the amount of heat required to change liquid mercury to its vapor state at its boiling temperature is 295 kj/kg. one kg of each substance is currently at its boiling point. how will the amount of thermal energy required to change each substance from a liquid to a gas differ?

There are 3 ways heat can be transferred: through solids, called , through liquids and gases , called , and through electromagnetic waves, called
