1.
When two lengths are added, their uncertainties combine by adding the:
percentage uncertainties
squares
absolute uncertainties
products
2.
A quantity y = x3. If x has a 2% uncertainty, y has:
6%
2%
5%
8%
3.
To test y = kx2 graphically, plot:
y against x
y against x2
y2 against x
ln y against x
4.
The uncertainty in a gradient is normally found from:
the largest error bar
the mean of all points
the intercept
half the difference between the steepest and shallowest lines
5.
A line of best fit through origin-expected data has a large positive y-intercept. This suggests:
perfect data
a systematic error
no uncertainty
too many repeats
6.
A plot of ln A against t has gradient −0.050 s−1. The decay constant λ is:
0.050 s−1
−0.050 s−1
20 s−1
0.69 s−1
