Pemarkahan -- kes 1 1. Maximum ONLY 4 marks EXPLAINING ALL THE TYPE OF RETAINING WALL. BUTTTT…… NOT CHOOSE ANYTHING OR CHOOSE MORE THAN ONE RETAINING WALL.    MARKS given only for the CORRECT REASONs

Pemarkahan -- kes 2 EXPLAINING ALL THE CHARACTERISTICS OF given RETAINING WALL BUTTTT……CHOOSE wrongly  MARKS only will be given AT WHAT YOU CHOOSE  MAX--- 8 MARKS

DECISION MAKING STEPS 1.Distinguish the characteristics given 2.Explain the properties of every chosen characteristics and give the reason. 3. Distinguish the most suitable material based on the characteristics stated. 4.Give reasons why the material chosen.

Q A new harbour is to be built at a new location. The suggested new location is either at a bay or a cape. Four models for the structure of the retaining wall are given. Table 12 below shows the location and the characteristics of the four retaining walls.

Explain the best location and the suitability of each characterictics in Table12. Determine the most suitable retaining wall to be used. Give the reason for your choice.

Worksheet

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

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

Question CharacteristicExplaination / reason Can receive more signal/wave All signal is focus to reciever High frequency, more energy / short wavelength – easy to reflect. Easy to receive the signal. The most suitable is KRepeat 1,3,5,7 ____ Diameter of the parabolic disc Distance of signal receiver from the centre of parabolic is ____ Type of wave transmitted is ____ Height of the parabolic disc from the ground is ______ Big Same as f microwave high

Question CharacteristicExplaination / reason Pressure transmitted equally Not easy to boil / volume remains constant Withstand high force Large force produce / Easy to stop The most suitable is LRepeat 1,3,5,7 _______________ brake fluid _______ boiling point ______ spring constant ____ ____ ratio Incompressible high Low ( 1:5)

Question CharacteristicExplaination / reason Can be absorb Suitable period can be detected Medium penetration Can detect radioactive ray The most suitable is YRepeat 1,3,5,7 State of matter is______ _______ half life _______ ray Type of detector is _____ liquid short beta GM tube

No 11 –2010 characteristicsExplaination Method of moving lawnmover -Push the handle - Bigger force produced Mass of lawnmower -Big -More stable // cut efficiently Size of cutter blade -Big size of cutter blade -Cut more more grass The angle between handle and the horizontal -large - Bigger downward force // not lift up -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

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 ………… (1,4,5,7) 7M

The most suitable _heating element____ is _____ Because _________________________________ ________________________________________ P, high melting point, low resistance, low ability to break at high temperature, and low oxidation level.

NO.3 CharacteristicExplaination / reason ____specific heat capacity. Easy get cold / becomes cool quickly ______size of ice cream box Easier to carry Material for outer box: ______ Poor conductor of heat ______ colour of outer box Does not absorb heat from surrounding quickly LOW smaller Plastic PVC Bright

The most suitable _ice cream container_ is _____ Because _________________________________ ________________________________________ R Low specific heat capacity, small size of ice cream box, material for outer box is plastic pvc and bright colour of outer box

No. 4 CharacteristicExplaination / reason ____ diameter Reduce the resistance of the cables _____density The cables will be lighter ______ rate of expansion Less expansion and sagging in the cable during hot day ______ melting point Can withstand high temperature / does not melting easily LOW HIGH Large LOW

The most suitable ______cable_______ is _____ Because _________________________________ ________________________________________ Q Large diameter, low density, Low rate of expansion and high melting point.
