The energy of an electron in a rigid box when it is in the next higher state is 19.6 eV
<h3>What is electron energy?</h3>
The energy carried by the electron when jumping from one energy level to another is called as electron energy.
Energy in the nth level for a rigid box of length L and mass of electron m is represented as
As the energy is proportional to n².
Substitute the value 3 for n in the above equation. So, we have the energy of an electron is
E₄ = 19.6 eV
Thus, energy of electron in a rigid box when it is in the next higher state is 19.6 eV.

Answer:
Options (3) and (6)
Explanation:
Janine drives 2.2 km East.
Since, distances measured in the East are positive,
Displacement = 2.2 km
Then she drives 4.4 km west
Displacement = -4.4 km
Followed by 1.7 km in the East
Displacement = 1.7 km
Total displacement = 2.2 - 4.4 + 1.7 = -0.5 km
km
Total distance covered by Janine = 2.2 + 4.4 + 1.7 = 8.3 km
d = 8.3 km
Therefore, Options (3) and (6) will be the answer.
Answer:
by using p = mv equation we can find v,
6 = 1.3 v
4.615 = v
