Firstly, solve 0=14-x^2 to find the horisontal distance to the edges of the tunnel. x1=sqrt(14), x2= -sqrt(14).

Integrate h=14-x^2 between x1 and x2 28*sqrt(14) -(2(sqrt(14)^3))/3. This is the requ...

To make life easier we often treat molecules as flat - for example we draw methane on a page as a carbon with 4 hydrogens bonded to it at perfect 90 degree angles. This isn't really the case. Electron-ele...

Starting with a(x - b)^2 - c, if we expand the bracket we get:

a(x^2 - 2xb + b^2) -c

Since we need to end up with the coefficient on x^2 being 3 and in the expression above x^2 is only multi...

ELISA, an acronym for enzyme linken immunoabsorbant assay, is a means of measuring the amount of a specific antibody in serum through treating a 96 well plate with antigens that stick well to the plastic ...

Historiography is history as written by academics who are experts in the areas they have studied, and so their commentary and interpretations are regarded as reliable and credible. Though not explicitly n...
