Explanation / Answer
1)
From the subrule,
we know that if f=x/y, the relative error on f is the relative error on x added in quadrature with the relative error on y.
So v = d/t.
dv/v = ((dd/d)2 + (dt/t)2)1/2
= ((0.13)2 + (0.08)2)1/2 = .15 or 15%
3)
a) discrepancy = adiff - aslit = 0.250 -0.271 = -.021 mm
b) EED = ( (0.005)2 + (0.005)2)
