Let's call
the frequency of the nth-harmonic and
the frequency of the (n+1)th harmonic, wish is the next harmonic.
Since the frequency of the nth-harmonic is n times the fundamental frequency f1:
then the difference between two successive harmonics is equal to the fundamental frequency of the tube:
so, by using 350 Hz and 280 Hz as successive harmonics, we find the fundamental frequency of the tube:
The wavelength of the first harmonic is twice the length of the tube:
And since we know both frequency and wavelength, we can find the speed of the wave in the tube, which is the speed of sound in the gas in the tube:
Answer:R=1607556m
θ=180degrees
Explanation:
d1=74.8m
d2=160.7km=160.7km*1000
d2=160700m
d3=80m
d4=198.1m
Using analytical method :
Rx=-(160700+75*cos(41.8))= -160755.9m
Ry= -(74.8+75sin(41.8))-198.1=73m
Magnitude, R:
R=√Rx+Ry
R=√160755.9^2+20^2=160755.916
R=160756m
Direction,θ:
θ=arctan(Rx/Ry)
θ=arctan(-73/160755.9)
θ=-7.9256*10^-6
Note that θ is in the second quadrant, so add 180
θ=180-7.9256*10^6=180degrees
Lightning is full of plasma because of charged particles. When lightning strikes, we know this because of this charged particles. Plasma! I have attached a picture to display what I am trying to convey! Best of luck.
Explanation:
According to newtons first law of motion:
'' a body will continue in its state of rest or uniform motion along a path unless it is acted upon by an external force".
A body in equilibrium that is floating will be stable and not move in any direction. Even if it moves, the motion will be constant wouldn't change.
- To move the body in any direction, one has to swim.
- Swimming is the application of an external force to counter the balanced forces at equilibrium on a body.
- This works when the net external force is greater than that the balanced forces.

Answer:comparing the total displacement and tota distance covered by Ben Jerry.
Explanation:
Total distance travelled by both is;
m+n=z
Total displacement of both is;
x+y=z
Therefore;
comparing equation 1 and 2;
x+y=m+n
