Organ pipe a, with both ends open, has a fundamental frequency of 310 hz. the third harmonic of organ pipe b, with one end open, has the same frequency as the second harmonic of pipe a. how long are (a) pipe a and (b) pipe b? (take the speed of sound to be 343 m/s.)

Part a)

55.3 cm

Part b)

41.5 cm

Explanation:

Pipe A is open at both ends so the fundamental frequency of this pipe is given as

here we know that

V = 343 m/s

now we have

Now we also know that second harmonic of pipe A and third harmonic of pipe B has same frequency

so we will have

question1

1,000 tons

question2

3: 8

question 3

store d

step-by-step explanation:

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .
