Density is a physical
property which describes the mass of a substance per unit of volume of the substance.
It is expressed as Density = m / V and it has units like g/cm^3. We use the
density given to solve the problem.
<span> Volume of the tank = 8 fishes / 0.2 fish / ft</span><span>³</span>
<span>Volume of the tank = 40 ft</span><span>³</span>
Answer:
we have formula of frequency :
frequency(f)= speed of sound(c)/wavelength(λ)
for wavelength we swipe it with frequency as follows
λ=c/f
λ=300,000,000/101,700,000
λ=2.949
Answer
= 60
