Answer:

28 J

Explanation:

Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work. In other words, it is energy in an object due to its motion or position, or both.

In physics, mechanical energy (Emech) is the energy associated with the motion and position of an object usually in some force field.

Therefore:

ME = KE + PE = 25 + 3 = 28 J

Describe what physical meaning is attributed to ψ 2

NNADVOKAT [17]

In quantum mechanics, $\psi^2$ the basic wave function has no physical meaning or significance. However, $|\psi|^2$ represents the probability distribution of particle in a given space.

Probability $\propto$ $|\psi|^2$

So when you will put a position and a time in $\psi^2$ function, it will give you the probability of finding the particle at that particular position and at the given time.
