Suppose that a body with initial temperature 2000 k is surrounded by a medium with temperature 300 k and that α = 2.0 × 10−12 k−3/s. (a) determine the temperature of the body at any time by solving eq. (ii).

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
