What particle determines an atom’s identity and never changes?

Protons is one of the composite subatomic particles (particles that never changes) and it identifies an atom

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

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
