In case of 1s order Splitting above answer is correct. in case of Non-1st Order splitting we should follow the following example
let for AMX(Quartet)
take our hand fingers for spectrum explanation(vomit thumb finger), distance between little finger to middle finger let it 'X' minus distance between showing finger and side finger of little finger let it 'y'.
Now the coupling constant is (X-Y)/2.
Kindly suggest if any mistake or difficulty to understand.

In NMR spectroscopy, a coupling constant is a measure of the interaction between different nuclear spins in a molecule. It provides information about the connectivity and relative arrangement of atoms in a molecule. The value of the coupling constant is influenced by the number of bonds and the dihedral angle between the coupled nuclei.

Is it true that the pH of a solution remains constant with increasing basicity?
No, it is not true.
Is it true that electrons have a constant speed and move in fixed orbits around the nucleus?
Yes this is true
Is the kinematics equation true if acceleration is not constant?
Kinematics does not require constant acceleration. There are different equations for different situations. So some of the equations will be valid even when the acceleration is not constant.
What is the best definition of fact?
It is something that is proven as true and indisputable.
Which statement is true regarding a fixed quantity of gas at a constant pressure?
At constant pressure the temperature and the volume of a gas are directly related; this the Charle Law.
A constant that multiplies a variable?
A constant that multiplies a variable is no longer a constant. By its very definition, a constant is something that can never be different. The result of variable multiplication is thus a variable, not a constant.I would say that the above answer is not necessarily true. The common equation for the area of a circle is: area = pi * r2The fact that you are multiplying the mathematical constant pi by a variable does not change the value of pi.Agree with the second answer. Jsut to add, a constant that multplies a variable is called a coefficient.
Is scientists keep all variables constant true or false?
independent variable
Will the definition's in a Dictionary be true?
Yes they are true in a Dictionary.
Is a polynomial of degree zero is a constant term true or false?
true!
Is it true that the pH of a solution remains constant with increasing basicity?
No, it is not true.
If velocity is constant then what is the true accelleration?
If velocity is constant, the true acceleration is zero. Acceleration is the rate of change of velocity, so if velocity is not changing, the acceleration is also zero.
Ventilation perfusion coupling means that more blood flows past functional alveoli than past nonfunctional alveoli?
True.
Is the converse of a definition always true?
No, the opposite of a definition is certainly not always true. That would depend on the definitions and the meaning of the opposite.
Characteristics of a mixture is It does not have a constant composition?
TRUE
Is it true that electrons have a constant speed and move in fixed orbits around the nucleus?
Yes this is true
Is this a true definition of the midge?
a pig
Why is a rock a mineral?
This is true by definition.
