i just wanted to know if HCV 2 has good problems i mean are they enough to get me thru jee
|
|
|

in ur solution LAMPARD have used time for the journey between P and Q whereas u had to use it only between P and R
|
|
|
|
if thats ur prob then try this out
when u complete reading a concept then go thru problems on it (solved)
after that try out solving easy sums and then slowly go up d ladder
u can do prob better
the main problem wid u is that u r low at confidence
i have faced the same problem and hence speaking out from my expierence

area of triangle in determinant form if the coordinates of points are known
x1 y1 1
x2 y2 1 =2a
x3 y3 1 a= area of triangle also limx  0 (sinx/x)=1 lim x  0 (tanx/x)=1 limxtends to 0 (1-cosx/x^2 )= 1/2 |

Greatdreams
if a salt is formed and yet we have excess of acid or base, then the acid and base combine with water (formed during neutralisation) to give H2 and hence we get another exothermic reaction
in this way the temperature should indeed increase further
so c should have least increase
this would b my xplanation to the problem
can u plz correct me where i went wrong
