skema jwpn .*wink

bismillahirrahmanirrahim.
ni skema jawapan physics section II yang sempat dicatit oleh tangan masa perkampungan ilmu hari tu.
*ni diambil dlm keadaan separuh sedar ye :D mm,betul. saya fokus habis masa physics ni ^^ *peace.
btw, kepada mentor2 yang hebat2 sekalian,kalau ada yang salah infom eh.*beselaa,manusia.

dan sekarang saya mencari skema untuk section I ,,,,,, dan seterusnya.
*tolong* sangat perlukan skema tu :D

*sape yang baik boleh bagi.hee.



SECTION II – DECISION MAKING
i)                    Charecteristic
ii)                   Reason

Q1 ( FORCE AND PRESSURE)
Characteristic of structure of ship


1)      Has a streamlined shape : To reduce water resistance
2)      High strength of metal used : To carry the heavy load,avoid wall break and withstand high temp.
3)      Has wide ship base cross section area : It will not sink deeper
4)      Has high volume of the air space in the ship : To reduce the density of ship so that the buoyancy become higher
Q2( FORCES AND PRESSURE)
A hydrometer that can be used to measure densities of concentrated acids

1)      The material is glass : It will not corrode to acid
2)      Diameter of stem is higher : To increase the sensitivity of hydrometer
3)      Diameter of shots is higher : To able the hydrometer stay up right
4)      High diameter of bottom bulb : To obtain bigger upthurst

Q3( FORCES AND PRESSURE)
Suitable motorcycle to move fast and safe when racing.

1)      Has low height : more stable because has lower centre of gravity
2)      Has lower mass : To reduce the inertia
3)      Has ABS : To reduce the motorcycle from jerking,prevent side way moving
4)      Has greater width of tyre : More stability for more support

Q4( FORCE AND PRESSURE)
Specification of components that can be used in brakesystem

1)      Has higher specific heat capacity of brake disc :  the rate of increase in temp. cause by the frictional force will decrease.
2)      Higher melting point of brake disc : The brake disc will not easily change in shape
3)      Compression of brake fluid is difficult : Because pressure will be transmitted uniformly to all direction. / to prevent the existence of air buble
4)      Material use of brake pads is ceramic : Can withstand high temp


Q5 (HEAT)
Liquid that are suitable to be used as a coolant for car engine

1)      High boiling point : It is not easily boiled
2)      Low viscocity : Liquid can flow at their temperature
3)      High specific heat capacity : It can absorb more heat
4)      Ability to react with metal is low :

Q6(LIGHT)
Characteristic of telescope to observe very far object

1)      Objective lens is convex lens : It can coverge the light to produce real image
2)      Focal length of objective is far : when the distance is higher, the magnification power is higher
3)      Large diameter of objective lens : More light can be trap and the image form is brighter


#kepada mentor-mentor hebat :  kalau salah atau nak topup apa2,,,,infom ehh. bantu saya dan sahabat2 lain dapat Aplus jugakk ye :)
