Steam at a pressure of 15 bar and a temperature of 320oc is contained in a large vessel. connected to the vessel through a valve is a turbine followed by a small initially evacuated tank with a volume of 0.6 m3. when emergency power is required, the valve is opened and the tank fills with steam until the pressure is 15 bar. the temperature in the tank is then 400oc. the filling process takes place adiabatically and kinetic and potential energy effects are negligible. determine the amount of work developed by the turbine, in kj.

Aspacecraft that renters the earth’s atmosphere drastically slows down. the amount of kinetic energy the spacecraft has as it reenters the earths atmosphere

What is the speed vfinal of the electron when it is 10.0 cm from charge 1?

Use the library or internet to research each planet. make a chart comparing the following: approximate surface temperature relative surface gravity compared to earth atmospheric gases water in any form: solid, gas, or liquid when you have completed your chart, use the information you have collected to answer the following questions: which is the hottest planet? which is the coldest planet? which planet's temperature is closest to that of earth? (note: water boils at 100°c/212°f. water freezes at 0°c/32°f) which planet has the greatest gravitational attraction? which planet has the least gravitational attraction? which planet's gravitational pull is closest to that of earth? do any of the planets have oxygen in their atmosphere? which planet's atmosphere most resembles that of earth? do any of the planets have flowing water? which planet's water resources (solid, gas, or liquid) might be close to the amount on earth? which planet most resembles earth in terms of all of the factors: temperature, gravity, atmosphere, and water? if earth became an uninhabitable planet, which planet do you think would be the next best to live on? explain your answer.
