Answer:  2 yd² = 2592 in²

<u>Step-by-step explanation:</u>

Use the following conversions: 1 yd = 3ft,  1 ft = 12 in

2\ yd\cdot yd\times \dfrac{3\ ft}{1\ yd}\times \dfrac{3\ ft}{1\ yd}\times \dfrac{12\ in}{1\ ft}\times \dfrac{12\ in}{1\ ft}\quad =\large\boxed{2592\ in^2}

(a) What resonant frequency would you expect from blowing across the top of an empty soda bottle that is 24 cm deep, if you assu
Kryger [21]

Answer:

a) 357.29 Hz

b) 535.9375 Hz

Step-by-step explanation:

v = Velocity of sound in air = 343 m/s

l = length = 24 cm

a)

l=\frac{1}{4}\lambda \\\Rightarrow \lambda=4l

f=\frac{v}{\lambda}\\\Rightarrow f=\frac{v}{4l}\\\Rightarrow f=\frac{343}{4\times 0.24}\\\Rightarrow f=357.29\ Hz

∴ Resonant frequency is 357.29 Hz

b) Here one third is filled with soda

So, length becomes l=24-\frac{24}{3}=16\ cm

f=\frac{v}{4l}\\\Rightarrow f=\frac{343}{4\times 0.16}\\\Rightarrow f=535.9375\ Hz

∴ Resonant frequency is 535.9375 Hz
