The steam turbine has an efficiency of 40.0%. A O steam engine has of 25.0%. Suppose both devices are provided
with 1000J of thermal energy. How much more useful work.
will the steam furbine do? Show your work.

Pleasssee help please

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
