Assuming a typical efficiency for energy use by the body, if a 69 kg person were to use the energy in this candy bar to climb stairs, how high could she go

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines. (2.15 mpa; 45.0 mw; 42.6%)

Photons with the highest energy have the longest period

Acamcorder has a power rating of 20 watts. if the output voltage from its battery is 9 volts, what current does it use?
