READ THESE INSTRUCTIONS FIRST Do not open this booklet until you are told to do so. Write your name, register number and class in the spaces at the top of this page and on any separate answer paper used. Write in dark blue or black ink. You may use a pencil for any diagrams or graphs. Do not use correction fluid or tape. Section A (40 marks) Answer all questions. Write your answers in the spaces provided on the question paper. Section B (30 marks) Answer all questions. Question 10 has a choice of parts to answer: 10 Either or 10 Or. Write your answers in the spaces provided on the question paper. At the end of the examination, circle 10 Either or 10 Or in the grid on the right to indicate which question you have answered. INFORMATION FOR CANDIDATES The intended number of marks is given in the brackets [ ] at the end of each question or part question. You are advised to spend no longer than one hour on Section A and no longer than 45 minutes on Section B. Candidates are reminded that all quantitative answers should include appropriate units. 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 use of an approved scientific calculator is expected, where appropriate. The acceleration due to gravity (or gravitational field strength) g is taken to be 10 m s -2 (or 10 N kg-1) near the Earth’s surface.

2016 End-of-Year Examination Secondary Three 2 Nanyang Girls’ High School Setters: AWL & TBH Physics II Section A (40 marks) Answer all questions. Write your answers in the spaces provided. 1 A student checks the purity of a small un iform aluminium block by measuring its density. He first recorded the dimensions of the block as follows: Height/ cm Breadth / cm Length/ cm 1st reading 2.25 1.92 2.05 2nd reading 2.23 1.90 2.04 Average 2.24 1.91 2.045 (a) Name the instrument that the student used. [1] (b) State one error that the student made in the tabulation of his results. [1] (c) He then went on to measure the mass of the block as 23.9 g and the weight of the block as 0.236 N. (i) Determine the gravitational field strength where the measurements were made. gravitational field strength = [1] (ii) Calculate the density of the block.
