cooling rate of sphere of 600K at external environment 200K is R …

WebGet an expert solution to A sphere maintained at temperature 600 K, has cooling rate R in an external environment of 200 K temperature. If its temperature falls to 400 K, the cooling rate will be: WebYou can actually use any measure of temperature with newtons law of cooling because it deals with temperature generally (no units). Its the same for the time variable. In his example, Sal uses an arbitrary 2 to represent 2 mins. That could actually represent 2 days, weeks, hours, or years. Essentially, then, what you get out of the equation for ... the rms speed of particle of mass 5
