Physical quantities and measurement techniques — practice question
A student secures a metre rule to the end of a bench, as shown in Fig. 1.1. A mass is fastened to the end of the rule.
He then moves the end of the rule through a small displacement. The rule moves up and down in oscillations. The student times ten full oscillations.
(a)[1]
State the name of a device used to measure the timing of the oscillations.
(b)[1]
Give a reason why the student times ten oscillations instead of just one.
(c(i))[1]
One reading is wrong. In the table, ring the incorrect reading.
(c(ii))[2]
Calculate the mean value for the time taken for ten complete oscillations.
(c(iii))[1]
Find the time for one full oscillation. Give your answer to two significant figures.
