Write in dark blue or black pen on both sides of the paper. You may use a soft pencil for any diagrams, graphs or rough working. Do not use staples, paper clips, highlighters, glue or correction fluid. Section A Answer all questions in the spaces provided. Section B Answer any two questions. Write your answers in the spaces provided. Candidates are reminded that all quantitative answers should include appropriate units. The use of an approved scientific calculator is expected, where appropriate. Candidates are advised to show all their working in a clear and orderly manner, as more marks are awarded for sound use of concepts than for correct answers. At the end of the examination, fasten all your work securely together. The number of marks is given in brackets [ ] at the end of each question or part question.

2 BVSS Section A Answer all questions in the spaces provided. 1 A student has a metal object. For examiner’s use (a) The student measures the mass of the object. State the name of the equipment used to measure the mass. ....................................................................................................................... [1] (b) The mass of the metal object is 1260 g. The volume of the metal is 150 cm3. Calculate the density of the metal. density = ………………………… g/cm3 [1] [Total: 2] 2 A scientist performs an experiment to investigate the motion of a loaded metre rule as shown in Fig. 2.1. Fig. 2.1

3 BVSS [Turn over A 100 g load is attached to the metre rule such that the centre of the load is a distance d away from the pivot. The rule is displaced a small distance to one side then allowed to swing and the time t taken for 10 complete swings is recorded. The results for the experiment are recorded in Table 2.1. Table 2.1 d / cm 70.0 75.0 80.0 85.0 90.0 t / s 16.80 17.10 17.60 17.90 18.40 T / s …………… 1.71 …………… 1.79 1.84 For examiner’s use (a) Calculate the period T for d = 70.0 cm and d = 80.0 cm in Table 2.1. [1] (b) On the graph below, plot the graph of T / s against d / cm and draw the best- fit line.
