​The light uniform bar in Fig 3 is equilibrium. The two beakers A and B contain water at the same temperature. The two blocks are made of the same material.
​If the temperature of the water in beaker A is now raised, explain why the beam tips to side A.
Assume the solid does not expand.

a) i) What is photoelectric effect?
ii) You are provided with the following: a photocell, a source uv light, a rheostat, a source of e.m.f, a milliammeter, a voltmeter and connecting wires. Draw a circuit diagram to show how photoelectric effect may be demonstrated in the laboratory. b) In a photoelectric effect experiment, a certain surface was illuminated with radiation of different frequencies and the stopping potential determined for each frequency ​Table 2 shows the results obtained. (i) Plot the graph of the graph of stopping potential (y-axis) against frequency.
