Suppose that when you measured D , you measured the fence at a slight angle, rather than straight across. (If you wanted to exaggerate this effect, suppose you measured the length from one corner to the opposite corner.) How would this affect your final measurement of g (for each part) - would you overestimate g , underestimate it, or neither? Quantitatively estimate the magnitude of the effect if the angle we were off by was one degree. How much would the magnitude of the effect differ between the two parts? Explain.
