The robot HooRU is lost in space, floating around aimlessly, and radiates heat into the depths of the cosmos at the rate of 13.1 W. HooRU's surface area is 1.55 m2 and the emissivity of its surface is 0.287. Ignoring the radiation that HooRU absorbs from the cold universe, what is HooRU's temperature T?

The temperature is  

Explanation:

From the question ewe are told that

   The rate of heat transferred is    

     The surface area is  

      The emissivity of its surface is  

Generally, the rate of heat transfer is mathematically represented as

=>        

where   is the Boltzmann constant with value  

substituting value  

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
