metal surface ,bcoz metal is agood conductor of heat
The answer is 5 hrs. The description is below.
D/72 + 1.0 = D/60
12 D = 72 x 60
D = 72 * 5 = 360 km
t= 360 / 72 = 5 hrs
photon energy proportional to frequency
is given to electron as kinetic energy
which is proportional to square of velocity
graph will be parabolic
It refers to heat flowing(transmitted) at a constant rate.
