kinetic energy of man ka kya tha
|

|
|
well rooney is wrong
here 30% of the light is reflected .so we have to consider that too.
the momentum of 30% light is changed by twice the amount
consider that also and u will get the correct ans

IF YOU THINK If you think you are beaten, you are.
Page 36 of 175
If you think you dare not, you don't!
If you like to win, but think you can't,
It's almost a cinch you won't.
you think you'll lose, you're lost;
For out in the world we find
Success begins with a fellow's will;
It's all in the state of mind.
If you think you are outclassed, you are,
You've got to think high to rise,
You've got to be sure of yourself before
You can ever win a prize.
Life's battles don't always go
To the stronger and faster man,
But sooner or later the man who wins
Is the man who thinks he can.

it wl weigh 11 kg
some say 1 kg,but u see it means that if on weighing machine i weigh 30 and u jump on my shoulder it will weigh still 30 kg.not practical,the normal force is bound to increase.
just give it a thought & u will find that it voilates conservation of mass

equate mgcos(<a) with electric force of repulsion
plz rate if satisfied
|
|
|
|
|
first consult some basic book for understanding basic concept
then switch on to R.D.SHARMA objective,TMH &&&&
IF U NEED STILL MORE PRACTICE TRY I A MARON
PLZ RATE ME IF SATISFIED

f(x)=min{x+1,|x|+1}
is the function diff at x=1?
if no plz explain fully

T half=30 days for a mix
after being seperated into 2 fractions
T half of one fraction =2 days
so other fraction wl show
a)constant activity b)increasing activity
c)t\T half =28 d)T half =30
plz explain fully
