Even when shut down after a period of normal use, a large commercial nuclear reactor transfers thermal energy at the rate of 150mw by the radio active decay of fission products. this heat transfer causes a rapid increase in temperature if the cooling system fails. (1 watt = 1 joule or 1w = 1j/s and 1mw = 1megawatt)calculate the rate of temperature increase in degrees celsius per second (°c/s) if the mass of the reactor core is 1.60×105kg and it has an average specific heat of 0.3349 kj/kg°c.

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
