A.in empty space

Explanation:

Radiant heat creates heath through both convection and radiation. Their purpose is to heat up an environment, aka empty space.  

beta decay is the answer

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
