Find the coefficient of determination for the fit? 2. Using the uncertainty analysis, find the uncertainty equation in the drag coefficient, 8 F CD 2, D2 TT force measured; v is free stream velocity,D is the where CD is Drag coefficient; F is points] diameter and e is the water density Use SI units. L15 3. Using the uncertainty analysis, find the length of hypotenuse and the uncertainty in calculating the length of hypotenuse of a right triangle. The uncertainties of base and height are given below: [10 points] Wh -3% --3 units h b 4 units

Explanation / Answer

Sol:

From pythagoreas theorem

Hyp2 =sum of squares of other two sides

AC2 =AB2+BC2

=32 +42

  =9+16

AC2 =25

AC=SQRT(25)

AC=5

5%--UNCERTAINITY
