Answer:
6.29 meters.
Explanation:
, where v is the speed of wave and f is the frequency of wave.
We are given that ,
The speed of sound is 346 m/s.
i..e v=346 m/s
A sound wave travels at a frequency of 55 H.
i..e f=55
the wavelength would be 6.29 meters.

Ok so the equation for momentum is:
v=p/m
So you would do:
7800/1200=6.5
So the answer is:
6.5 m/s
Hope this helps :)
V= 1/3 π r²h
this is the formula for a cone hope this helps :)
optical density would increase the refraction angle going in to the material
there may be a relation between opt density and mass density ... kg/m^3
