CAPE Physics Unit 1 · 2013 · Paper 2 · Question 2(c)(i)

Two students measure the speed of sound. One claps d metres from a wall, synchronizing claps with echoes. The other measures the time for 20 claps (from the first clap to the last echo after the twentieth clap). This is repeated for various d values, and results are in Table 2.

Complete Table 2 on page 8 by inserting the missing values.
