An open organ pipe is 2.46 m long, and the speed of the air in the pipe is 345 m/s.

a. What is the fundamental frequency of this pipe?

Fundamental frequency is 70.12 m

Explanation:

For an open organ pipe, the fundamental frequency is given by :

n = 1 for fundamental frequency

v is speed of sound in air, v = 345 m/s

l is length of open organ pipe, l = 2.46 m

Substituting values in above formula. So,

So, the fundamental frequency of this pipe is 70.12 m.

c

explanation:

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
