Atruck with a heavy load has a total mass of 9100 kg. it is climbing a 15â incline at a steady 15 m/s when, unfortunately, the poorly secured load falls off! immediately after losing the load, the truck begins to accelerate at 1.5 m/s2.

Which statement best explains why an object weight less on mercury than it does on earth

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%)
