A freight train leaving a train yard must exert force of 2.5 x 10 to the 6th power in order to increase its speed from rest to 17. m\s, during the process the train must do 1.10 times 10 to the 9th power of work

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines. (2.15 mpa; 45.0 mw; 42.6%)

Asher cycles 12 miles in 16 hours. what is his speed?

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =
