^ is ka answer ms main kya hai?

D

 

[arlery]

The way I did it was first I got pressure = density*g*h
=80*1030*9.8
=807520

then add 100,000 Pa to it.

So you got 907520 Pa so D

 

[abrraza]

how D?

EMF is the amount of energy stored in the battery converted to electrical energy per unit charge passing through the battery.

P.D. is the amount of electrical energy per unit of charge converted to other forms of energy in while passing through a component.

can sumone plzzzz explain da answer to question.no 13 and 33 m/j2010 variant 1...!!!

hey, about Q13.

there is always a way to adjust the forces to make it zero unless they are equal.

 

[ShootingStar]

Please answer my doubt on page 81

[yubakkk]

cse v=lamda*f to find f
then find max speed
a=2m
and use 0.5m(max v)^2

 

[aliya_zad]

mass= 2x 10^-3( print not clear)

 

[yubakkk]

hey explaim my q. of page 72 about cro q.

 

[hassam]

work will be integral of this F against extensiongraph equation

[hassam]

how its .07 j

 

[hassam]

ohh kk i got it

 

[hassam]

1997 question myt get repeated..so try it
