23. Answer CharacteristicExplaination / reason The ______ Water is calmer ______retaining wall. Decrease the wavelength / higher water pressure at higher depth. ______ surface Reduce energy, wave is reflected at different direction. ______ retaining wall Protect form high wave / overflow of water. 8 marks BAY SLOPING UNEVEN HIGH

25. The most suitable __________________ is _____ Because _________________________________ ________________________________________ 2 marks W RETAINING WALL LOCATED AT BAY, SLOPING RETAING WALL, UNEVEN SURFACE ANDHIGH RETAINING WALL TOTAL : 10 marks

27. No 11 – characteristicsExplaination Method of moving lawnmover -Push the handle - Bigger force produced Mass of lawnmower -Big -To increase the stability Size of cutter blade -Big size of cutter blade -Increase the cutting area of cutting grass The angle between handle and the horizontal -large - Force exerted to the ground bigger -Therefore, I choose lawnmover M, -because it has push handle, big mass of lawnmower, big size of cutter blade and has large angle between handle and horizontal line 1 3 4 5 6 7 9 10

31. No 12 characteristicReason Connection of cell - series Increase the voltage Connection of battery -Positive terminal of cell to negative terminal of next cell To allow the flow of current Connection of resistor and bulb -series Increase the resistance Connection of bulb - parallel If one bulb blow, another bulb still function -the most suitable circuit is X -Because …………. 1 2 5 4 7 9 10 (1,4,5,7) 7M
