Question

By means of physiological adaptations that are still not very well understood, sperm whales are thought to be able to hunt for their food at depths of between 350m and 3000m .

Write a function that wall merge the contents of two sorted {ascending oruci / arrays of type double values, storing the result in an array output parameter (still in ascending order). The function should not assume that both its input parameter arrays are the same length but can assume that one array does not contain two copies o( the same value. The result array should also contain no duplicate values. Hint: When one of the input arrays has been exhausted, do not forget to copy the remaining data in the other array into the result array. Test your function with cases in which (1) the first array is exhausted first, (2) the second array is exhausted first, and (3) the two arrays are exhausted at the same time (i.e., they end with the same value). Remember that the arrays input to this function must already be sorted.

Explanation / Answer

A)

Pmin=rho*g*h=1000*9.8*350=34.3 E5 Pa


Pmin= rho*g*h=1000*9.8*3000=294 E5 Pa


B)

Pmin= 34.3E5/1.03E5=33.3 atm


and Pman=294E5/1.03E5=285.43 atm


C)

Area=2*pi*2*16+2*pi*(2^2)=226.194 m^2


==> force= Pressure*Area= 294E5*226.194=6.65 E9 N
