a circular plate of radius 5 meters is submerged in a 100 meter lake. calculate the hydrostatic pressure on the plate if the plate is lying horizontally and vertically.

how do I know which n to use, I see a lot of people going up to sin^7/7! but why 7?

I got an answer. I want to make sure it's correct.

I got an answer but I want to make sure it is correct. Thank you for who can help me.

How do you do this ,and what is the answer?

Please try again, keeping in mind that the centroid (x, y) is given by x = 1 A b x[f1(x) − f2(x)]dx a and y = 1 A b 1 2 [f1(x)]2...

I need to integrate from 0-t. I am told to set u= Erf and u'= (2e^-x^2)/pi^1/2. v' is 1 and v=x. i am also told that the answer is t Erf(t)+ ((e^-t^2)-1)/pi^1/2 how many...
