The potential difference between a storm cloud and the ground is 1.14 × 108 v. if a bolt carrying 5 c falls from a cloud to earth, what is the magnitude of the change of potential energy of the charge? 1. 272.0 2. 92.0 3. 508.0 4. 705.0 5. 287.0 6. 52.0 7. 744.0 8. 57.0 9. 1355.0 10. 426.0 answer in units of j.

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%)

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative
