L = Length of tube = 2.5 m
v = Velocity of sound in air = 344 m/s
Distance between nodes is given by
Where n = 0, 1, 2, 3, ...
Making n+1 = n
where n = 1, 2, 3 .....
For fundamental frequency n = 1
Frequency is given by
The fundamental frequency is 68.8 Hz
First overtone
Second overtone
The overtones are 137.6 Hz, 206.4 Hz
745.92 hz (b)
this is hte answer only because i seen it on the question lol

Answer:
melting of rock deep underground.
Explanation:
The melting of rocks deep underground does not produce sedimentary rocks. Most igneous rocks are produced by this process.
When molten rocks underground called magma is solidified in the subsurface, it results into the formation of igneous bodies.
- Sedimentary rocks forms by the accumulation of sediments.
- Inside the basin where the sediments are deposited, they are compacted, cemented and lithified.
- Chemical and physical weathering of rocks produces sediments.
