READ THESE INSTRUCTIONS FIRST Write in soft pencil. Do not use staples, paper clips, highlighters, glue or correction fluid. Write your name, Civics group and Index Number on the Answer Sheet in the spaces provided. There are thirty questions in this paper. Answer all questions. For each question there are four possible answers, A, B, C and D. Choose the one you consider correct and record your choice in soft pencil on the separate Answer Sheet. Read the instructions on the Answer Sheet very carefully. Each correct answer will score one mark. A mark will not be deducted for a wrong answer. Any rough working should be done in this booklet. The use of an approved scientific calculator is expected, where appropriate. This booklet consists of 14 printed pages.

3 1 A flat head drill bit is used to drill holes of small depth. The drill bit can drill holes with a diameter size of (40.0 ± 0.5) mm. The depth of the hole has an uncertainty of ± 1mm. If the total pe rcentage uncertainty of the volume made by the hole is less than 10%, what is the minimum depth, in mm, which the drill bit can make? A 15 B 14 C 13 D 12 2 A petrol gauge in a car indicates the volume V of fuel in the tank. V is given by the angular deflection θ of the pointer on a dial. Below are the calibration curves for the four different gauges. For high fuel levels in the tank, which gauge would be most sensitive? 3 A ball is thrown upwards at an angle to the horizontal with an initial speed. Assuming that air resistance is not negligible, which of the following statements is incorrect? A The time taken for the flight up to the highest point is longer than the time taken for the flight down. B The maximum height reached by the ball is smaller than that with negligible air resistance. C The horizontal range of the ball is shorter than that with ne
