Answer:
f1 = 58.3Hz, f2 = 175Hz, f3 = 291.6Hz
Explanation:
lets assume speed of sound is 350 m/s.
frequencies of a standing wave modes of an open-close tube of length L
fm = m(v/4L)
where m is 1,3,5,7......
and fm = mf1
where f1 = fundamental frequency
so therefore: f1 = 350 x 4 / 1.5
f1 = 58.3Hz
f2 = 3 x 58.3
f2 = 175Hz
f3 = 5 x 58.3
f3 = 291.6Hz
Explanation:
As wine and cheese are consumed together,it means that they both are complimentary goods.
As per law of demand,the fall in price of a complimentary good would increase the demand and shift the demand curve of the other to the right.
The equilibrium quantity of cheese would increase and shift to right when the price of wine falls.
