An ambulance with its siren on drives towards you. What happens to the wavelength of the sound you hear?
[Wavelegnth decreases]

answer; (d) spontaneous processes are characterized by the overall conversion of order to disorder;

i don't understand. explain it clearly

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
