Question

What is a neucleus ?​

Answer 1

A certain number on being divided by 27, gives 103 as quotient and 7 as remainder. Find the number.

2788

$\huge \bold{solution}$

Therefore,

The number is (27 X 103) + 7

⁣          2781 + 7

⁣        2788

Answer 2

Answer:

First postulate of Quantum mechanics:

Every physically-realizable state of the system is described in quantum mechanics by a

state function ψ that contains all accessible physical information about the system in that

state.

Second postulate of Quantum mechanics:

If a system is in a quantum state represented by a wavefunction ψ , then

PdV dV 2

= ψ

is the probability that in a position measurement at time t the particle will be detected in

the infinitesimal volume dV.

Third postulate of Quantum Mechanics:

Every observable in quantum mechanics is represented by an operator which is used to

obtain physical information about the observable from the state function. For an

observable that is represented in classical physics by a function Q(x,p), the corresponding

operator is Q(x, p) .

Fourth (Fundamental) postulate of Quantum mechanics:

The time development of the state functions of an isolated quantum system is governed

by the time-dependent SWE Hψ = ih∂ψ / ∂t

, where H= T+ V is the Hamiltonian of the

system.
