What should the student do to reduce the risk of burning herself with the hot water? [1 mark] 0 2 . 2 Describe how the student should use the equipment in Figure 2 to compare the power of the infrared radiation emitted by each surface. [4 marks] Question 2 continues on the next page 6 *06* IB/M/Jun22/8464/P/2F Do not write outside the A student investigated how the power of the infrared radiation emitted from a flask box changed with time. Table 1 shows the results. Table 1 Time in seconds Power in watts 0 8.0 60 7.2 120 6.5 180 5.9 240 5.4 300 5.0 360 4.7 420 4.5 0 2 . 3 Describe the pattern shown by the data in Table 1. [2 marks] 0 2 . 4 What is the most likely value for the power of the infrared radiation emitted after 480 seconds? Use Table 1.

Figure 3 shows an infrared detector and a Leslie Cube filled with hot water. Figure 3 0 2 . 5 Give one advantage of using a Leslie Cube rather than the equipment in Figure 2 on page 4. [1 mark] 0 2 . 6 The teacher improved the demonstration by using four infrared detectors connected to a data logger and computer. Each detector was pointed at a different surface of the Leslie Cube. The distance between the surface and the detector was the same in each case. Give two reasons why this improved the demonstration.

Figure 4 0 3 . 1 Draw an arrow on Figure 4 to represent the weight of the apple. [1 mark] 0 3 . 2 The apple has a mass of 0.150 kg gravitational field strength = 9.8 N/kg Calculate the weight of the apple. Use the equation: weight = mass × gravitational field strength [2 marks] Weight = N 9 *09* Turn over ► IB/M/Jun22/8464/P/2F Do not write outside the 0 3 box . 3 The apple in Figure 4 is stationary. Why is the apple stationary? [1 mark] Tick () one box. The resultant force on the apple is downwards. The resultant force on the apple is upwards. The resultant force on the apple is zero. Question 3 continues on the next page 10 *10* IB/M/Jun22/8464/P/2F Do not write outside the box 7 When the apple is ripe it falls from the tree and accelerates towards the ground. 0 3 . 4 Why does the apple accelerate? [1 mark] Tick () one box. The resultant force on the apple is downwards. The resultant force on the apple is upwards. The resultant force on the apple is zero. 0 3 . 5 The acceleration of the apple is 9.8 m/s2 The velocity of the apple changes from 0 to 4.9 m/s Calculate the time taken for the apple to fall to the ground. Use the equation: time taken = change in velocity acceleration [2 marks] Time taken = s 11 *11* Turn over ► IB/M/Jun22/8464/P/2F Do not write outside the box 0 4 Figure 5 shows a compass. Figure 5 0 4 . 1 Why does the compass always point in the same direction when it is not near a magnet? [1 mark] Tick () one box. The compass is not magnetic. The Earth has a magnetic field. There is no force acting on the compass. 0 4 . 2 What material could the needle of the compass be made from? [1 mark] Tick () one box. Aluminium Copper Plastic Steel 12 *12* IB/M/Jun22/8464/P/2F Do not write outside the Figure 6 shows a coil of wire. box There is a current in the coil. The circles show the position of f [Show More]
