A storm front moves in and Rachel and Pam notice the column of mercury in the barometer rises only to 736 mm. Assume the density of mercury is 13, 000 kg/m 3 (a) What is the change in air pressure?
(b) What if their barometer was filled with water instead of mercury, how high does the column rise? Density of water = 1000 kg/m

a

b

Explanation:

From the question we are told that

   The position of the column of mercury in the barometer is  \

   The density of mercury is  

Generally the  pressure of the atmosphere at that column is mathematically represented as  

=>      

=>      

Generally the atmospheric pressure at sea level (Generally the pressure before the change in level of the mercury column)  is  

Generally the change in air pressure  is mathematically represented as

=>  

=>  

Generally the height which the column will rise to is mathematically evaluated as  

Here is the density of water with value  

So

=>
