Question

Chemical reactions can be recognized by the presence of heat, light, or gas formation. The ultimate outcome for any chemical reaction is the

change from a solid to a liquid.
presence of sound.
formation of a new chemical substance.

Answer 1

Answer:

Let us write the given data and solve the question

Density = U

Cross section of plates = b

Separation = d

Fundamental frequency (n) = ?

SOLUTION:

Let us use that formula here

n = 1/2L  √T/μ

As we already know the value of T from the given data

Let us try to derive the value of T

T =  -dU/dx  =  1/2(k-1)E₀ bV²/ d      equation 1

Let us apply the value of T in frequency formula (n)

Then,

n =   1/2L √(k-1)E₀bV² /2dμ

This is final equation or Fundamental Frequency which we require
