Answer 2

howz that??

Answer 3

Answer 4

is that rite..?

Answer 10

@experimentX @campbell_st @waterineyes

Answer 11

also you can do silly mistake

Answer 12

any mathematical problem

Answer 13

@estudier @cwrw238

Answer 14

you guy got the ans ?

Answer 15

no

Answer 16

DAMN IT U R RITE....ITs S^2

Answer 17

can you help me? @heena

Answer 18

I did do a silly mistake...marked the wrong option

Answer 19

is the ans is c?

Answer 20

but it is in option b @amriju

Answer 21

yaa you are right @heena

Answer 22

how?

Answer 23

b is s^3/2

Answer 24

so easy guys listen
here they are saying
f=S ok
nw we knw
w=f.s
w=s.s
w=s^2

Answer 25

yaa scroll up and see your answer on the top @amriju

Answer 26

ok @heena thnx......

Answer 27

if u want to put contnt after removing proportionality ign u can but later u have to again remove that contant a they are asking abu proportional

Answer 28

*constant

Answer 29

int of ks.ds is ks^2/2....prop to s^2

Answer 30

what? i don;t understand

Answer 31

@heena

Answer 32

\[\int\limits_{0}^{S} kS.dS = kS ^{2} /2....that means prop \to S ^{2}\]

Answer 33

thnx...... @amriju

Answer 34

nthing leave it if u dont get that a it doent m8r and ye by integration too

Answer 35

thnx.......guys

Answer 36
