A noise created by small earthquake at a depth of 1200m in the ocean propagates upward and eventually reaches a bird flying above, at an altitude of 400m. Calculate how long it takes for the noise to reach the bird. For the seawater use E = 2.34 x 109 N/m2 , rho =1030kg/m3 , and for air, γ = 1.4, and T= 2700 K)

Complete Question

The time taken is

Explanation:

Generally velocity of the noise in water is mathematically represented as

substituting into the variable with value given in the question

=>

Generally the time taken is mathematically represented as

substituting into the variable with value given in the question

=>

The velocity of the noise in air is mathematically represented as

Here  R is  the gas constant with value

The  time taken is  

=>    

=> The  total time is mathematially represented as

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
