... Questions will be a mixture of multiple choice, short answer, calculations and extended openresponse questions. There is a separate practical endorsement. Paper 1 will test Topics 1-7 (though the Year 10 Mock will test Topics 1-5 for Combined, or 1-6 for Physics) and Paper 2 will test Topics 8 – 15. ...

... Quick Quiz 23.3 Answer: (e). In the first experiment, objects A and B may have charges with opposite signs, or one of the objects may be neutral. The second experiment shows that B and C have charges with the same signs, so that B must be charged. But we still do not know if A is charged or neutral ...

... 23. (1974) The forces produced by two springs as they are stretched are shown in the graph above. Spring 1 indicated by the dashed line is linear (Hookian), but spring 2 is not. The period of oscillation for a mass attached to spring 2 is: a. dependent on amplitude but never greater than for spring ...
