A ball rolls down a ramp five times. The times are $1.95\ \text{s}$ , $2.05\ \text{s}$ , $2.10\ \text{s}$ , $1.90\ \text{s}$ and $2.00\ \text{s}$ . Using the mean absolute error, what is the percentage error of the mean time?

Type your answer as a number (a decimal point is allowed). A wrong answer may cost marks.

← A screw gauge has a pitch of 1 mm and 100 circular divisions. It has a **negative** zero error of 0.03 mm. On a ball bearing, the linear scale shows 4 mm and circular division 45 is on the datum line. What is the diameter of the bearing, in micrometres?The resistance of a wire is found from R = V/I, with V = (100 ± 5) V and I = (10 ± 0.2) A. What is the percentage error in R? →
