low as 0-9 its 4th root is 0-974. Hence if the actual value isanywhere between 0-9 and 1, the assumed value of 0-9 will not make an errorof more than 2^ per cent, in the value of the temperature. 6. That the planet ultimately radiates out all the heat received from thesun, no more and no less. This… … Mg. 2.Making these six suppositions, let us calculate the temperature of variousparts of this ideal planet. Consider a band between latitudes A and A + dX. The area receivingheat from the sun at any instant, if projected normally to the stream ofsolar radiation, is (Fig. 2) 2r cos A r^A cos A = 2r^…
