Question

Fect Question 3 0/1 pts For the same table with width 0.985 +0.002 m and length 2.013 + 0.002 m, what is the uncertainty in the area you calculated? 0.002 Since A=lw, we need to use the uncertainty propagation for multiplication (which can also be derived from the general calculus expression for combining uncertainties!). Refer to the quick guide or review the document on propagation of uncertainty and the examples therein.

Answer 1

uncertainity =A*sqrt((dl/l)²+(dw/w)²) =(0.985*2.013)*sqrt((0.002/0.985)²+(0.002/2.013)²)

=0.004
