6) Repeat experiment 5) a) but now use the stored energy meter. Why do you think the change takes place. charge remains constant
PilotLPTM [1.2K]

Answer:

the energy comes from the increase in the electric field

Explanation:

The capacitance is

      C = ε₀ A / d

The electric charge on the condenser plates

    Q = C ΔV

     

The stored electrical energy is

       U = ½ C ΔV²

       ΔV = E d

     U = ½ (ε₀ A / d) (E d)²

    U = ½ ε₀ A d E²

We see that the stored energy is proportional to the square of the electric field, so the capacitor can increase its energy with increasing voltage

In short, the energy comes from the increase in the electric field

what is the closest to the order of magnitude of the energy rquired to split a nucleus in to its individual protons and neutrons
skad [1K]

Answer:

More than two million electron volts.

Explanation:

More than two million electron volts energy are needed to break or split a deuteron into a proton and a neutron. Nuclear binding energy is the type of energy that is required to split an atom's nucleus into protons and neutrons. The deuteron is an isotope of hydrogen that is composed of a proton and a neutron and it is a stable particle. Very huge amount of energy is needed for the splitting of nucleus due to the presence of heavy particles i.e. proton and neutron.
