You need to prepare a 0.199-mm-diameter tungsten wire with a resistance of 3.09 kï. how long must the wire be? the resistivity of tungsten is 5.62 ã 10-8 ïâ·m.

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%)

Alfred pushes on a heavy box, but cannot move it. the box has a lot of inertia motion friction gravity

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?
