Write in dark blue or black pen. You may use an HB pencil for any diagrams or graphs. Do not use staples, paper clips, glue or correction fluid / tape. Section A Answer all questions. Section B Answer one question. 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 Physics than for correct answers. The number of marks is given in brackets [ ] at the end of each question or part question.

4 2 Fig. 2.1 shows a simplified cross -section of an industrial hydraulic oil pump system. A force F1 is applied downwards on Piston 1. The cross-sectional area of piston 1, A1, is 0.020 m 2. It transmits pressure through an incompressible oil to move Piston 2. The cross-sectional area of piston 2, A2, is 0.016 m2. Fig. 2.1 (a) If F1 = 150 N, (i) calculate the pressure exerted on the oil by Piston 1. pressure = …......................

5 (b) Due to friction between the moving parts, the hydraulic oil absorbs heat, causing its temperature to rise. To prevent overheating, a cold water jacket surrounds the metal base of the oil reservoir. The hot hydraulic oil transfers its excess thermal energy through the metal base of the reservoir into the flowing cold water. (i) Using particulate model of matter, describe how thermal energy is conducted within the solid metal base. …....................................................................................................................................... …....................................................................................................................................... …....................................................................................................................................... …....................................................................................................................................... …....................................................................................................................................... …...............................................................................................................................

6 3 Fig. 3.1 shows a 12 kg uniform wooden barrier plank of length 3.0 m pivoted at point P. The pivot is located 0.50 m from the left end of the plank. An electric motor is attached via a vertical cable at pivot A to pull down and raise the barrier. The barrier is currently held horizontally in equilibrium. The gravitational field strength is 10 N / kg. Fig. 3.1 (a) State two conditions required for the uniform barrier to remain in static equilibrium. ….................................................................................................................................................. ….................................................................................................................................................. ….................................................................................................................................................. ….........................................................................................................................................

7 4 A ship uses sonar to detect the depth of the ocean floor. The sonar system sends out a pulse of ultrasound and detects the reflected pulse returning from the ocean floor. The speed of sound in seawater is 1500 m / s. The time between sending the pulse and receiving the reflected pulse is 0.40 s. (a) State wh
