Air enters an adiabatic turbine at 900 k and 1000 kpa. the air exits at 400 k and 100 kpa with a velocity of 30 m/s. kinetic and potential energy changes are negligible. if the power delivered by the turbine is 1000 kw, a. find the mass flow rate. b. find the diameter of the duct at the exit

Curious carl calculated the density of a cube to be 4.50 g/cm3. what is the density of the cube in g/l?

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts.ki k i = nothing ev request answerprovide feedback
