PLEASE HELP.. I WOULD BE SO HAPPY!! ILL MAKE YOLO THE BRAINLIEST Dwight and Andy are trying to lift a large box containing a new office copy machine. In order to maintain grip, each of the men is pushing toward each other with a force of 50 N. The copier has a mass of 300 Kg. Using the normal value for gravity on earth, what is the weight of the copier? ​

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. (3.32 mw; 9.69 mw; 4.25 mw; 5.82 mw)

Wavelength, frequency, and energy are related. what happens to a wave as it’s wavelength gets shorter?

Could someone . i have tried to solve myself but my calculation is off
