Weak Nuclear  

Explanation:

The force which acts at level of subatomic particles and governs the radioactive decay of an atom is known as weak force. It is a fundamental force which governs the interaction between subatomic particles for atomic decay. Its range is limited to the diameter of a proton. It is a fundamental force stronger than gravitational force but weaker than electromagnetic force.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

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
