While playing her guitar , karen plucks one string with increasing levels of force. What effect does this have on the sound prod
2 answers:
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

Answer:
The direction is due south
Explanation:
From the question we are told that
The energy of the electron is
The earths magnetic field is
Generally the force on the electron is perpendicular to the velocity of the elecrton and the magnetic field and this is mathematically reresented as
On the first uploaded image is an illustration of the movement of the electron
Looking at the diagram we can see that in terms of direction the magnetic force is
generally i cross k = -j
so the equation above becomes
This show that the direction is towards the south
