A dart in a dart gun has 100) of potential energy from the spring in the gun. After the dart is shot (no longer in contact with the spring) how much kinetic energy does it have if there is no friction in the gun?
Answer a-100j Answer b-0j Answer c- is impossible to determine Answer d-50j

Which statement about covalent bonds is true

In what direction does the medium move relative to the direction of the wave? explain.

Steam is generated in a boiler of a cogeneration plant at 10 mpa and 450°c at a steady rate of 5 kg/s. in normal operation, steam expands in a turbine to a pressure of 0.5 mpa and is then routed to the process heater, where it supplies the process heat. steam leaves the process heater as a saturated liquid and is pumped to the boiler pressure. in this mode, no steam passes through a condenser, which operates at 20 kpa. (a) determine the power produced in the turbine and the rate at which process heat is supplied in this mode. (b) determine the power produced in the turbine and the rate of process heat supplied if only 60 percent of the steam is routed to the process heater and the remainder is expanded to the condenser pressure.
