Buoyancy problem, please check my work :)
Can you check my work here?
A crown is weighed in air and submerged in water. The scale reads 7.84 N in air and 6.86 N in water.
find (a) the buoyant force (b) the volume of the crown (c) the density of the crown (d) is the crown made of gold...
Please double check my work !
Hi, I basically did out all the poroblems. I just need someone to double check whether I made any mistakes in the answers or procedures. (My prof is a real dickhead and marks down for the smallest mistake) Also can I simplify any answers, just like obvious stuff...
Hi could you please say if this is right or wrong and if it is not where I went wrong.
I got the question:
Find the volume of the area between y=x-x^3 from 0 to 1 revolved about the y-axis.
So here are my workings:
V = \pi \int_0^1{x^2dy}
V = \pi \int_0^1{x^2 \frac{dy}{dx}dx}...
