Hydrogen is an element made of only one kind of atom
Answer:
The fundamental frequency and length of the pipe are 100 Hz and 1.7 m.
Explanation:
Given that,
Frequency f = 550 Hz
Frequency f' = 650 Hz
We know that,
AMT pipe is open pipe.
(b). We need to calculate the length of the pipe
Using formula of organ pipe

For 550 Hz,
...(I)
For 650 Hz,
...(II)
From equation (I) and (II)



(a). We need to calculate the fundamental frequency for n = 1
Using formula of fundamental frequency

put the value of L


Hence, The fundamental frequency and length of the pipe are 100 Hz and 1.7 m.

the speed of something in a given direction.
Explanation:
Answer:
Explanation:
The concept of elastic and inelastic demand is applied.
for an elastic demand, the elasticity must be greater than 1 and for an Inelastic demand, the elasticity must be less than 1.
The steps and appropriate calculation is as shown in the attached file.
