This question appears to be a continuation from a previous section (1(iii)) and references a graph. It is combined with question 47 due to text extraction. (iv) The graph of I against t° is related by the equation t = where x is the distance from the centre of the mass of the pendulum bob to the point at which it is tied to the cotton thread and n is the number of oscillations. Using this equation and the slope obtained in 1(iii), estimate the acceleration due to gravity, g (cm/s). (v) From your graph, determine the l-intercept in cm. (vi) What does the value obtained in 1(v) signify?

You have been provided with a cell E, the key K, resistance box R, ammeter A and the voltmeter V. Proceed as follows: Set up the circuit as shown in Figure 2. (a) (b) With the key open, observe and record the reading E on the voltmeter. (c) Set the resistance R equal to 7 S, close the key and then record the reading of the current I flowing through the circuit and the potential difference V across the cell. (d) Repeat the procedure in 2 (c) with R=5 S2, 4 S2, 2S 2, and 1 2. For each case, record the Corresponding values of I and V. Questions (i) Prepare a table of values including I (A), V (V) and (E - V) (V) (ii) Plot a graph of (E-V) in volts against I in amperes. (iii) Compute the slope of the graph plotted in 2 (ii). (iv) What is the physical meaning of the slope in 2 (iii)? (v) If a house alarm is rated 3 2 is connected in the circuit, determine the current that must flow through the circuit alarm to operate it.
