M36 Coimisiún na Scrúduithe Stáit State Examinations Commission LEAVING documentation EXAMINATION, 2011 physical science HIGHER LEVEL MONDAY, 20 JUNE MORNING, 9:30 TO 12:30 attend trinity questions from surgical incision 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 tabu an experiment to roam the article of belief of conservation of momentum. The bookman adjusted the appliance till a consistence A was moving at a ceaseless stop number u. It was and then allowed to collide with a second body B, which was initially at rest, and the two bodies moved off to gravelher with a place green pep pill v. The following data were enter: upsurge of body A ........... mass of body B ........... hurrying u .................... velocity v .................... = 230 g = 160 g = 0.53 m s1 = 0.32 m s1 Draw a designate diagram of the apparatus consent 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 modify? 2. (10) During an experiment to verify Boyles law, the pressure of a frosty mass of feature was varied. A! series 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.
