For this case we must find the roots of the following equation:

We have to:

Where:

Substituting the values:

We have two roots:

Answer:

The answer is A .2d/T
Since d is directly proportional to the heat lost it should be the numerator
since T is inversely proportional to the heat lost it shoudl be the denormirator
that is 1/T ; 2 is the constant
the actual formula is R = kd/T
