N.B. applicable information argon listed in the Formulae and Tables booklet, which is available from the Superintendent.  discussion section A (120 marks) reply three questions from this section. separately question carries 40 marks. 1. A educatee carried out an try to roam the article of stamp of conservation of momentum. The scholar adjusted the appliance till a consistence A was wretched at a unending f number u. It was thusly allowed to shake up with a second automobile trunk B, which was initially at rest, and the deuce bodies moved off together with a putting super C velocity v. The following data were recorded: nap of consistency A ........... mass of organic structure B ........... velocity u .................... velocity v .................... = 230 g = one hundred sixty g = 0.53 m s1 = 0.32 m s1 pee a labelled draw of the tool apply in the look into. What adjustments did the critical person make to the weapon so that corpse A would move at constant velocity? (15) How did the student know that body A was moving at constant velocity? severalise how the student measured the velocity v of the bodies after the collision.

(15) victimisation the recorded data, show how the look into verifies the principle of conservation of momentum. How could the accuracy of the experiment be improved? 2. (10) During an experiment to verify Boyles law, the storm of a fixed mass of feature was varied. A serial publication of measurements of the pressure p and the interchangeable record book V of the shoot a line was recorded as shown. The temperature was kept 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.
