  2. June 2011 Getting Easy Marks

  3. 1(a) the mains live wire is brown 1(d) …and give the unit. power in Watts(W) / kiloWatts(kW) 2(a) work done=force applied x distance moved just use the equation; note that force is applied along the slope, not straight up 4 marks

  4. The whole question tests basic revision. (a)simple atomic structure (b)an atom is neutral because number of protons=number of electrons (c)isotopes have variable number of neutrons (d)an ion has gained or lost electron(s) 5 marks

  5. 5(a) on a velocity/time graph, the distance travelled is equal to the area under the line 6(a)(i)basic revision: circuit symbols ammeters in series and voltmeters in parallel with the component being tested 6(a)(ii)AC means current reverses direction 6(b)(i)rearrange before use: R=V/I 6(b)(iii)stretched so must be elastic strain energy 8 marks

  6. 7(a) rearrange before use: a=F/m Use resultant force in equation 3 marks

  7. These are not all the marks available, but nobody doing Higher tier should have missed many of these twenty. • Some marks were gained by recall, some by knowing what to doin the exam. • Now total the marks that you missed – how would they have boosted your grade?
