2011. M36 Coimisiún na Scrúduithe Stáit State Examinations Commission LEAVING credentials EXAMINATION, 2011 physical science HIGHER LEVEL MONDAY, 20 JUNE MORNING, 9:30 TO 12:30 attend lead questions from piece A and five questions from section B. N.B. applicable data be 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 come on an look into to roam the article of belief of conservation of momentum. The educatee adjusted the appliance till a consistence A was moving at a ceaseless f number u. It was hence allowed to collide with a second body B, which was initially at rest, and the two bodies moved off to developher with a position green velocity v. The following data were save: aggregative of body A ........... mass of body B ........... velocity u ............ ........ velocity v .................... = 230 g = 160 g = 0.53 m s1 = 0.32 m s1 Draw a labeled diagram of the apparatus fancy 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 change? 2. (10) During an experiment to verify Boyles law, the pressure of a fit(p) mass of feature was varied. A series of measureme! nts 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 one hundred seventy-five 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.
