CXXViil FACULTY OF SCIENCE Describe the spectrometer and explain how to use it to determine the angle of prism Explain how the velocity of sound in metal rod may be compared with the velocity in air How may the result be made use of to determine Young's Modulus of Elasticity What is meant by the absolute unit of current Explain how an electric current is measured by means of copper voltameter battery consists of 12 cells each having an of 12 volts and an internal resistance of ohms how must the cells be arranged to produce the greatest current through an external resistance of ohms ball with an electric charge upon it is placed in con- tact with an equal ball which has three times the charge upon it on being separated cm from one another the force of repulsion between them is equal to 16 dynes What were the original charges on the two balls 10 Give the laws of induction of currents and describe ן experiments showing the production of currents when coil is rotated in magnetic field What is meant by magnetic field -mv ic FIRST YEAH The same paper as set for the Faculty of Arts DIVISION OF ENGINEERING ARCHITECTURE AND APPLIED SCIENCES XI emt$tn State the "law of multiple proportions" and show how it is exemplified by the following analyses of the oxides of copper Cu 8875 Cu 79 75 Ο 11-25 Ο 2025 100Ό0 ΙΟΟΌΟ Cu 63 16
