P=hdg so h=p/dg
Q11- its B. this is because 1stly the road has an upward force on the wheels which is the opposite of the weight of the car. so its either a or b. then the 2nd force is applied so the car can move. so the force is applied to the right which causes the car motion to the right so it is B.http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_s03_qp_1.pdf

i guess i answered u in the other thread right?

Q16- power is work done per unit time. B is also used to calculate power but C is the proper definition.
Q20- P=hdg so h=p/dg
pressure will be 10% of Po so 10Po/100 = Po/10
substituting u get Po/10dg
Q32- V=7.5 so 7.5/15=0.5A
Q33- 1st add the ones in series. 16kohm up and 16kohm down. then use the formula R1R2/R1+R2 = 16*16/16+16 = 8kohm
its C?
A and B have H-bonds as well. In D Vander Waals forces are becoming stronger as its solidifiacation. In C there are only Vander Waals forces and its melting so the bonds need to be overcome.Help needed

F=change in momentum/timeDo you know how to do Qs 10 in physics May/June 2007 paper?

Q24- X is not a hydrocarbon as hydrocarbons dont react with PCl5. X can either be acid or alcohol but we cant still distinguish which one it is. X is not an aldehyde for sure as X does not react with 2,4-dinitrophenylhydraxine. So we cant be sure whether its an alcohol or acid but we can say that it certainly is not an aldehydeCan any body please solve these qs for me frm this ppr.........

Q14- A because max height means it covered half the distance so the energy also gets halved.
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
