A well-insulated turbine operating at steady state develops 30 MW of power for a steam flow rate of 50 kg/s. The steam enters at 30 bar with a velocity of 80 m/s and exits as saturated vapor at 0.08 bar with a velocity of 150 m/s. Neglecting potential energy effects. Determine the inlet temperature, in ∘C.

To do work, this truck uses energy stored in chemical fuel and an electrical battery. how much total energy does this truck put out?

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit

Hydrogen and helium are both members of?
