According to the universal law of gravitation _____.
2 answers:
The correct answer is:
a. everything has a gravitation force because everything has mass
In fact, the universal law of gravitation states that every object with mass M exerts an attractive, gravitational force to any other object with mass m, and the size of this force is given by:
where G is the gravitational constant, and r is the distance between the two objects.

Answer:
The amplitude of vibration of string will increase due to which loudness of sound will increase
Explanation:
As we know that the guitar is based on the principle of Resonance. When string of the guitar vibrates at a given frequency then the sound produced in the hollow part of the guitar will also be at same frequency.
This is known as resonance condition, so guitar will produce same frequency sound as that of frequency of string.
Now if the string is plucked with increasing level of force then it will increase the amplitude of vibrations of the string due to which the sound produced in the guitar will also be of same level.
So here we can say that amplitude and intensity of sound related as
so on increasing amplitude the intensity will increase and hence it will produce loud sound
