Figure 1 Figure 2 shows how the power output from solar and wind energy resources varies in a typical year. Figure 2 5 *05* Turn over ► IB/M/Jun23/8464/P/1H Do not write outside the box 8 Explain the changes in power output from solar and wind energy resources between 2014 and 2019. You should include an explanation of the change in power output during a typical year. [6 marks] Turn over for the next question 6 *06* IB/M/Jun23/8464/P/1H Do not write outside the 0 2 Body analysis scales use the electrical resistance of a person’s legs to estimate the box percentage of water in the person’s body. Figure 3 shows body analysis scales. Figure 3 The person’s legs contain both solid tissue and water. A student used resistors to model the solid tissue and water. The student connected a 20 Ω resistor in parallel with a resistor, R. Figure 4 shows the circuit diagram. Figure 4 0 2 . 1 To determine the total resistance of both resistors, a voltmeter must be connected into the circuit. Complete Figure 4 to show where the voltmeter should be connected.

Explain why the student’s answer cannot be correct. [2 marks] Use the Physics Equations Sheet to answer questions 02.3 and 02.4. 0 2 . 3 Write down the equation that links current (I), resistance (R) and potential difference (V). [1 mark] 0 2 . 4 When the total resistance of the resistors was 7.5 Ω the current in the circuit was 480 mA. Calculate the potential difference across the two resistors. [3 marks] Potential difference = V 8 *08* IB/M/Jun23/8464/P/1H Do not write outside the The student investigated how the resistance of R affected the total resistance of box the circuit.
