At 20 oC the densities of fresh water and ethyl alcohol are, respectively, 998 and 789 kg/m3. Find the ratio of the adiabatic bulk modulus of fresh water to the adiabatic bulk modulus of ethyl alcohol at 20 oC.

The ratio is  

Explanation:

From the question we are told that

   The density of fresh water is  

     The density of ethanol is  

Generally speed of a wave in a substance is mathematically represented as

Here B is the adiabatic bulk modulus of the substance  while  is the density of the substance

So at constant wave speed

=>  

=>      

=>  

Here     and  

So

  =>      

  =>      

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
