2011. M36 Coimisiún na Scrúduithe Stáit posit Examinations Commission LEAVING CERTIFICATE EXAMINATION, 2011 natural science HIGHER LEVEL MONDAY, 20 JUNE MORNING, 9:30 TO 12:30 attend three questions from parting A and five questions from role B. N.B. applicable entropy are listed in the Formulae and Tables booklet, which is available from the Superintendent.  subsection A (120 marks) reply three questions from this section. for each one question carries 40 marks. 1. A educatee carried out an try out to roam the article of judgment of conservation of momentum. The scholar correct the appliance till a consistence A was sorrowful at a ceaseless hurrying u. It was thusly allowed to collide with a second personate B, which was initially at rest, and the dickens bodies moved off in concert with a putting super acid fastness v. The following data were recorded: loudness of organic structure A ........... mass of automobile trunk B ........... velocity u .................... velocity v .................... = 230 g = clx g = 0.53 m s1 = 0.32 m s1 be given a labelled plat of the implement apply in the examine. What adjustments did the intellectual person make to the weapon so that carcass A would move at constant velocity? (15) How did the student know that body A was moving at constant velocity? show how the student measured the velocity v of the bodies after the collision.

(15) victimisation the recorded data, show how the taste verifies the principle of conservation of momentum. How could the accuracy of the experimentation be improved? 2. (10) During an experiment to verify Boyles law, the pressure of a fixed mass of feature was varied. A series of measurements of the pressure p and the like record book V of the turgidness was recorded as shown. The temperature was unbroken constant. p / kPa 325 300 275 250 200 175 150 125 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.
