MBELEKI SUBJECT: ERRATA – PHYSICAL SCIENCES P1 GRADE 12 SEPTEMBER 2017 DATE: 15 SEPTEMBER 2017 The Physical Sciences P2 Grade 12 September was written on Thursday, 07 September 2017. It was brought to our attention that during the course of marking a number of corrections and additions were detected. In order to ensure that a standardised approach to marking is adopted across the Province and ensure that learners are not disadvantaged, the examiner and moderator were asked to prepare an errata which should address all the concerns raised. ERRATA CORRECTIONS REMARKS/COMMENT YES/ NO 1.6 One of the free-body diagrams below D is correct. error shows all forces acting on the ball. ACCEPT C … whilst it is moving up the incline … 4.3.3  Statement indicated 7 m from A–C. No change. (follow the What the arrow shows does not memo) change the question.  The statement is clearly  Learners were required to use stating that … slides “Energy principles” to calculate the down 7 m from A to C on error kinetic frictional force between B and an incline plane.

(Follow the No memo) error The question is not asking anything about Source A has frequency lower intensity which has to do with more than the Threshold frequency ejected electrons but the reference is the … so no electrons will be threshold. ejected.(so number is Zero At source A – No electrons (f < fo) but at electrons) source B – there are electrons (f > fo). Source B has frequency higher than the threshold frequency … So electrons will be ejected.(so number is greater than Zero) We asked that this must be brought to the attention of all educators marking the papers and sincerely apologise for the inconvenience. However, it must be noted that these amendments are required in order to ensure that a fair and equitable assessment of learners can take place. Yours in education. 15 September 2017 MS N.
