A particular atom contains 2 protons in the nucleus. It is ionised and contains only one orbiting electron. Calculate the energy released (i. e., a positive value) when the electron makes a transition from the n=5 energy level to the n=2 energy level. Give your answer in SI units (J).

Which statement best describes how private industry decides where to spend the money on research and development

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%)
