Acircular parallel-plate capacitor with a spacing of 1.6 mm is charged to produce a uniform electric field with a strength of 2.7 × 106 n/c. what plate radius is required if the stored charge is −1.07 µc? the permittivity of a vacuum is 8.8542 × 10−12 c2/n · m2. answer in units of m.

There are weak or strong attractive forces between atoms of liquids with a high viscosity

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%)
