A force of 100 N is applied to a crate at an angle of 60° to the horizontal surface. The force causes the crate to move 2 m across the floor. How much work is done on the crate? a. 50 J
b. 100 J
c. 200 J

Will pushing on a car always change the cars mechanical energy? what must happen for the cars kinetic energy to increases?

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%)

In the circuit shown below, with each bulb holding a resistance of 60 ohms, how many amps of current are flowing? express your number as a decimal.
