October/November 2008 1 hour
READ THESE INSTRUCTIONS FIRST Write in soft pencil. Do not usestaples, paper clips, highlighters, glue or correction fluid. Write your name, Centre number and candidate number on the Answer Sheet in the spaces provided unless this has been done for you. There are forty questions on 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 theseparate 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.
This document consists of 17 printed pages and 3 blank pages.

A student uses a digital ammeter to measure a current. The reading of the ammeter is found to fluctuate between 1.98 A and 2.02 A. The manufacturer of the ammeter states that any reading has a systematic uncertainty of ± 1 %. Which value of current should be quoted by the student? AB C D (2.00 ± 0.01) A (2.00 ± 0.02) A (2.00 ± 0.03) A (2.00 ± 0.04) A
