Instructions
Answer all questions in the spaces provided. Do all rough work in this book. Cross through any work you do not want to be marked.
Information
There are 100 marks available on this paper. The marks for questions are shown in brackets. You are expected to use a calculator where appropriate. You are reminded of the need for good English and clear presentation in your answers. When answering questions 03.1, 10.6, 13.2 and 14 you need to make sure that your answer: ‒ is clear, logical, sensibly structured ‒ fully meets the requirements of the question ‒ shows that each separate point or step supports the overall answer.
Advice
In all calculations, show clearly how you work out your answer.

Figure 1 shows what scientists over 1000 years ago thought the solar system was like. Figure 1
Give one way that the historical model of the solar system shown in Figure 1 is different from what we now know about the solar system. [1 mark]
Give one way that the solar system shown in Figure 1 is the same as what we now know about the solar system. [1 mark]
Figure 2 shows two iron nails hanging from a bar magnet. The iron nails which were unmagnetised are now magnetised. Figure 2
Complete the sentence. Use a word from the box. [1 mark]
The iron nails have become __________________________magnets.

unmagnetised iron.^ Each of the three metal bars in^ Figure 3^ is either a bar magnet or a piece of The forces that act between the bars when different ends are placed close togetherare shown by the arrows. Figure 3
Which one of the metal bars is a piece of unmagnetised iron? [2 marks] Tick one box. Bar 1 Bar 2 Bar 3 Give the reason for your answer.

Figure 4 shows two students investigating reaction time. Figure 4
Student A lets the ruler go. Student B closes her hand the moment she sees the ruler fall. This investigation can be used to find out if listening to music changes the reaction times of a student. Explain how. [4 marks]

A student suspended a spring from a laboratory stand and then hung a weight from the spring. Figure 5 shows the spring before and after the weight is added. Figure 5
Which distance gives the extension of the spring? Tick one box. [1 mark] from J to K from K to L from J to L
0 4.^1
The student used the spring, a set of weights and a ruler to investigate how the extension of the spring depended on the weight hanging from the spring. Figure 6 shows that the ruler is in a tilted position and not upright as it should be. Figure 6
How would leaving the ruler tilted affect the weight and extension data to be recorded by the student? Use answers from the box to complete each sentence. Each answer may be used once, more than once or not at all. [2 marks]
The weight recorded by the student would be ____________________________ the actual weight. The extension recorded by the student would be __________________________ the actual extension of the spring.

The student repeated the investigation with three more springs, K, L and M. The results for these springs are given in Figure 8. Figure 8
All three springs show the same relationship between the weight and extension. What is that relationship? [1 mark] Tick one box. The extension increases non-linearly with the increasing weight. The extension is inversely proportional to the weight. The extension is directly proportional to the weight.
Which statement, A, B or C, should be used to complete the sentence? Write the correct letter, A, B or C, in the box below. [1 mark] A a lower spring constant than B the same spring constant as C a greater spring constant than From Figure 8 it can be concluded that spring M has the other two springs.

Small water waves are created in a ripple tank by a wooden bar. The wooden bar vibrates up and down hitting the surface of the water. Figure 9 shows a cross-section of the ripple tank and water. Figure 9
Which letter shows the amplitude of a water wave? Tick one box. [1 mark] J K L
The speed of the wooden bar is changed so that the bar hits the water fewer times each second. What happens to the frequency of the waves produced? Tick one box. [1 mark] Increases Does not change Decreases

Figure 10 shows an incomplete electromagnetic spectrum. Figure 10
What name is given to the group of waves at the position labelled A in Figure 10? Tick one box.^ [1 mark] infrared radio visible light X-ray
Electromagnetic waves have many practical uses. Draw one line from each type of electromagnetic wave to its use.

The drag lift pulls the skier with a constant resultant force of 300N for a distance of 45 m. Use the following equation to calculate the work done to pull the skier up the slope. work done = force × distance [2 marks]
Work done = _______________ J
Question 7 continues on the next page
0 7.^3
At the top of the slope the skier leaves the drag lift and skis back to the bottom of the slope. Figure 13 shows how the velocity of the skier changes with time as the skier moves down the slope. Figure 13
After 50 seconds the skier starts to slow down. The skier decelerates at a constant rate coming to a stop in 15 seconds. Draw a line on Figure 13 to show the change in velocity of the skier as she slows down and comes to a stop. [2 marks]
