Calculate the resistance of the cable. [3 marks] Resistance = Ω Use the Physics Equations Sheet to answer questions 01.4 and 01.5. Write down the equation which links efficiency, total energy input and useful energy output. [1 mark] The total energy input to the National Grid from one power station is 34.2 GJ. The National Grid has an efficiency of 0.992 Calculate the useful energy output from this power station to consumers in GJ. [3 marks] Useful energy output = GJ Do not write outside the box 10 Turn over ► *03* IB/M/Jun23/8463/1H 4 0 2Figure 2 shows the equipment a student used to determine the specific heat capacity of iron. The iron block the student used has two holes, one for the heater and one for the thermometer. Figure 2 0 2 . 1 Before the power supply was switched on, the thermometer was used to measure the temperature of the iron block. The student left the thermometer in the iron block for a few minutes before recording the initial temperature. Suggest why.
