去年bell curve有多少啊？

哥们   12是去不了sp的   顶多去个tp或rp

1（a）pressure is defined as the force acted on per unit area
(c)as temperature increases ,gas molecules gain kentic energy ,hence it move faster and the frenquency of collisions of air molecules and wall increases ,which increases the pressure
2(c)the potential energy transfers to knetic enenrgy and heat energy due to firction ,hence kentic enenrgy increased is much less than potential enenrgy
3(a)(ii)thermal couple is very responsible to temperature change ,hence it can meassure the rapidly temperature change
(b)(ii)the temperature of the hot air is much less than boiling point of water ,hence water  molecules vaporize rather than boil
7（a)it reverse the direction of output current every half revolution
(c)the direction of the current opposes the direction of induced current ,which prevents the coil from rotating
9(a)the distance travelled from 0.2 to 0.4is more than distance travelled from 0 to 0.2
(b)metal will be charged when rubbed with cloth,however,as metal is very conductive of electrons ,it will be neturalised then
10 or (iii)the centre of the sack truck is very low ,hence it is unstable and easy to lift
            the arm of sack truck is very long ,hence it increases the moment of the force to lift the truck

去年的话，私立学校的10分内才进得了sp，今年不比去年号多少，只是没有大选可能松一些
