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

Lena [83]

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

$I = kA^2$

so on increasing amplitude the intensity will increase and hence it will produce loud sound

You are on the roof of the physics building of your school, 46.0 m above the ground. Your physics professor, who is 1.80 m tall,

Elena L [17]

Answer:

The professor should be 3.60 meters away from the place where the egg would fall.

Explanation:

To calculate this first we need to calculate the time it would take for the egg to fall the distance from the roof to the professor's head (46m-1.8m=44.2m).

The formula for free fall is:

y=1/2*g* $t^{2}$

solving for t it would be

$\sqrt{\frac{y}{g*1/2}} =t$

replacing

$\sqrt{\frac{44.2m}{9.8m/s^2*1/2}} = t = 3.00s$

Now that we have the time it would take the egg to get from the roof to the desired height we need to calculate the distance the professor would travel in that time so we know to release the egg when he's exactly at that distance.

Since he is traveling at a constant speed the formula is

x=v*t

replacing

1.20m/s * 3.00 s = x = 3.60 m
