The lowest energy of electron in an infinite well is 1.2*10^-33J.
To find the answer, we have to know more about the infinite well.
<h3>What is the lowest energy of electron in an infinite well?</h3>
- It is given that, the infinite well having a width of 0.050 mm.
- We have the expression for energy of electron in an infinite well as,


- Thus, the lowest energy of electron in an infinite well is,

Thus, we can conclude that, the lowest energy of electron in an infinite well is 1.2*10^-33J.

Answer:
Potential energy of spring = 24 Joules.
Explanation:
Given the following data;
Spring constant = 85N/m
Extension, e = 0.75m
Mass = 25kg
To find the potential energy of a spring
Potential energy of a spring is given by the formula;
P.E = ½ke²
Substituting into the equation, we have
P.E = ½*85*0.75²
P.E = 42.5 * 0.5625
P.E = 23.91 ≈ 24 Joules
P.E = 24 Joules
