A weak Bronsted-Lowry base is a weak proton acceptor, where the proton is in the form of H+, so the conjugate acid formed contains one more H atom and an extra positive charge.

The force of a spring can be calculated by the expression:
F = kx where k is a constant and x is the distance.
From the problem statement, we can solve the value of k from the initial conditions given as F = 25 N and x = 2 cm.
25 = k (0.02)
k = 1250
We use the work formula which is force times the distance resulting to the expression:
W = (1/2)(kx^2)
W = (1/2)(1250)(0.03^2)
W = 0.5625 J
Actually Welcome to the concept of Atomic Structure.
Since, We all know that, To draw any Electron-Dot Structure, we always have to know the exact Number of valence or free electrons of any atom or molecule, hence
The Correct Answer is :-
D. Number of valence electrons.
