Small drops of water fall at regular intervals from a leaking tap (faucet)
Immediately after a drop has fallen, a student puts an empty measuring cylinder under the tap, to catch the drops
At the same time, her friend starts a stopwatch
After 50 drops have fallen, she stops the stopwatch
Fig. 1.2 shows the reading on the stopwatch at the start and finish of this experiment
Fig. 1.3 shows the measuring cylinder at the finish
