Which is the correct symbol for an isotope of bromine with 35 protons and 38 neutrons?

Explanation:

The correct symbol would be

The top number is the atomic mass of this form of Bromine. The bottom number is its position on the periodic table. The 73 is a bit light. Usually the weight is closer to 80.

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
