The diagram shows a wooden beam PQ, of negligible weight, which is attached to a wall by a hinge at P and kept in a horizontal position by a vertical rope attached at Q. The beam is 3.0 m in length. A man of weight 800 N walks along the beam from P to Q. Q hinge beam rope man wall P What is the distance of the man from P when the tension in the rope at Q becomes equal to 500 N?

Four nails A, B, C and D are tested to find which makes the strongest permanent magnet. One of the nails is placed against a bar magnet and the number of paper clips which the nail can support is recorded. N S nail bar magnet paper clips The bar magnet is then removed and the number of paper clips remaining attached to the nail is recorded. Each nail is tested individually. Which nail becomes the strongest permanent magnet?

The diagram shows an incomplete circuit. The temperature and light levels around the circuit remain unchanged. A P Q Four electrical components are connected in turn across PQ. The cell is reversed and the four electrical components are connected again in turn across PQ. For which component is there a significant change in the magnitude of the current?
