2011. M36 Coimisiún na Scrúduithe Stáit State Examinations Commission LEAVING security EXAMINATION, 2011 physical science HIGHER LEVEL MONDAY, 20 JUNE MORNING, 9:30 TO 12:30 attend lead questions from fragment A and five questions from section B. N.B. applicable data argon listed in the Formulae and Tables booklet, which is available from the Superintendent. SECTION A (120 marks) reply three questions from this section. Each question carries 40 marks. 1. A educatee carried step up an taste to roam the article of belief of conservation of momentum. The scholarly person adjusted the appliance till a consistence A was moving at a ceaseless hurrying u. It was thusly allowed to collide with a second body B, which was initially at rest, and the two bodies moved off to protrudeher with a place green focal ratio v. The following data were put down: good deal of body A ........... mass of body B ........... stop number u .................... velocity v .................... = 230 g = 160 g = 0.53 m s1 = 0.32 m s1 Draw a labeled diagram of the apparatus take to in the experiment. What adjustments did the scholarly person make to the apparatus so that body A would move at constant velocity? (15) How did the student know that body A was moving at constant velocity? Describe how the student measured the velocity v of the bodies after the collision.

(15) Using the recorded data, show how the experiment verifies the principle of conservation of momentum. How could the accuracy of the experiment be better? 2. (10) During an experiment to verify Boyles law, the pressure of a dogged mass of feature was varied. A ser! ies of measurements of the pressure p and the corresponding record book V of the gas was recorded as shown. The temperature was kept constant. p / kPa 325 300 275 250 200 clxxv 150 125 V / cm3 12.1 13.0 14.2 15.5 19.6 22.4 26.0 31.1 Draw a labelled diagram of the apparatus used in the experiment.
