first measure the inital length of spring.how was the scale used for the extension Q1(b)?
then take the measure after the mass was hung.
extension = final - inital

first measure the inital length of spring.how was the scale used for the extension Q1(b)?
Q9's last part was 3.2 !!!!!
The resistors were in parallel and 2.5
So, 1/2.5 + 1/2.5 = 4/5, which reversed makes total resistance 1.25.
The current was 1.6 and power loss is equal to current squared multiplied into resistance
1.6x1.6x1.25 : 3.2W

my answers were:hey can u tell me q.9 last parts answers ???
more than good;What is friction? It is a force that opposes motion....caused by roughness of a surface...measured in newtons.? Is it good enough?
pheww !! THANK God !! it was 384 W !!my answers were:
second last = 380 something something
last = 12.8
its the last one im worried aboutpheww !! THANK God !! it was 384 W !!
exactly 12.8 W !!its the last one im worried about
what was your answr for last part. 12.8 ?
Any1 ????Ok, help me here :
Q1) Mass, extension one.
Q2) Car's acceleration and stuff
Q3) House heating
Q4) angle of incidence and 32. something as angle of refraction one
Q5) wave motion and stuff
.
.
Q8) Wire and stuff
Q9) transformer wala
Q10) Gamme rays and Beta rays and stuff
What were question 6 and 7 about ?!?!?
BUT , aren't those resistors in parallel ?exactly 12.8 W !!
i wrote friction is a force opposing body in motion and it acts in opposite direction is it okWhat is friction? It is a force that opposes motion....caused by roughness of a surface...measured in newtons.? Is it good enough?
yes , it wasThere was an MCQ whose answer was 1010mm.
they are cheap as well as light.What's the use of optic fibres!
it was in series, even if it was not the the current was AC...so anyway the resistance should be taken on series Add itSeries, i guess!
noBUT , aren't those resistors in parallel ?
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.
