Write your name, entre number and candidate number on the nswer Sheet in the spaces provided unless this has been done for you. O NOT WRITE IN NY ROES. There are forty questions on this paper. nswer all questions. For each question there are four possible answers,, and. hoose the one you consider correct and record your choice in soft pencil on the separate nswer Sheet. Read the instructions on the nswer Sheet very carefully. Each correct answer will score one mark. mark will not be deducted for a wrong answer. ny rough working should be done in this booklet. Electronic calculators may be used. This document consists of 15 printed pages and 1 blank page. I17 6_554_11/3RP ULES 217 [Turn over

2 1 micrometer is used to measure the diameter of a uniform wire. 2 screw wire fixed scale rotating scale What is done to obtain an accurate answer? Make the micrometer horizontal and then use the scales to find the reading. Subtract the fixed-scale reading from the rotating-scale reading. Subtract the rotating-scale reading from the fixed-scale reading. Use the scales to find the reading and add or subtract any zero error. 2 car s acceleration and maximum speed are improved by using an engine of smaller mass and greater driving force.
