Answer:
Explanation:
Two frequencies with magnitude 150 Hz and 750 Hz are given
For Pipe open at both sides
fundamental frequency is 150 Hz as it is smaller
frequency of pipe is given by
![f=\frac{nv}{2L}](https://tex.z-dn.net/?f=f%3D%5Cfrac%7Bnv%7D%7B2L%7D)
where L=length of Pipe
v=velocity of sound
for n=1
and f=750 is for n=5
thus there are three resonance frequencies for n=2,3 and 4
For Pipe closed at one end
frequency is given by
![f=\frac{(2n+1)}{4L}\cdot v](https://tex.z-dn.net/?f=f%3D%5Cfrac%7B%282n%2B1%29%7D%7B4L%7D%5Ccdot%20v)
for n=0
![f_1=\frac{v}{4L}](https://tex.z-dn.net/?f=f_1%3D%5Cfrac%7Bv%7D%7B4L%7D)
![f_1=150\ Hz](https://tex.z-dn.net/?f=f_1%3D150%5C%20Hz)
for n=2
![f_2=\frac{5v}{4L}](https://tex.z-dn.net/?f=f_2%3D%5Cfrac%7B5v%7D%7B4L%7D)
Thus there is one additional resonance corresponding to n=1 , between
and ![f_2](https://tex.z-dn.net/?f=f_2)
It doesn't work the same as the other because one is ultraviolet while the other is infrared.
<u>Answer:</u>
The speed of the two stuck together blobs of putty immediately after colliding = 1.5 m/s
<u>Explanation:</u>
The momentum is conserved before and after collision. That is initial momentum value is equal to final momentum value.
Initial momentum = 2 * 3+ 2 * 0 = 6 kg m/s
So final momentum = 6 kg m/s
Final mass of body = 2 + 2 = 4 kilogram
Final velocity of body = Final momentum/ Final mass = 6/4 = 1.5 m/s
So, the speed of the two stuck together blobs of putty immediately after colliding = 1.5 m/s
This is what I found online: "<span>For a person with normal hearing, when it comes to pitch the human hearing range starts low at about 20 Hz. That’s about the same as the lowest pedal on a pipe organ. On the other side of the human hearing range, the highest possible frequency heard without discomfort is 20,000Hz. While 20 to 20,000Hz forms the absolute borders of the human hearing range, </span>our hearing is most sensitive in the 2000 - 5000 Hz frequency range<span>." So i'm guessing it's 100,00 since none of those are lower than 20

Answer:
The answer is "perpendicular and distance".
Explanation:
The Perpendicularity would be the connection of two lines that meet in such a right angle perpendicularity (90 degrees). It extends to all geometric objects involved.
The Distance was its cumulative motion of a body regardless of the direction that's why the value "d" is perpendicular to the distance from the transformer.
