A boy standing in front of a cliff blows a whistle and hears the echo after 0.5s. He then moves 17 metres further away from the cliff and blows
the whistle again. He now hears the echo after 0.6s. Determine the speed of the sound.

Figure 6 shows a narrow beam of X-rays passing between two metal plates in air. The plates are connected in series with a switch, a cell and a milliameter.
It is observed that when the switch is closed a current flows in the milliameter. Explain this observation.
