How'd your physics Papers go ?

werent v supposed to do clockwise torque=anticlockwise?

 

[Translucent231]

yes we were supposed to do that... but the question had a bit of a thing to notice... there was one force on right acting downwards (making clockwise ) there were 2 forces on left of pivot one was downwards ( ANTICLOCKWISE ) but the other which we had to calculate was UPWARDS (CLOCKWISE) .. i hope u get the point

What was the answer for that electrical energy qs in which power was 300W and time was 1 hour??

 

[asad.manutd9]

losing nearly 20 in theory and 7-8 in mcqs , worst paper ever for me , can i have any hope for an A Grade ??

Well, I changed Watts into Kilo watt and got 0.3 and multiplied it with 1 to get KW/H=0.3
You?

thats wat we were suppose to do and I got 5 N
6 x 3 = 2 x F + 4 x 2
F comes 5

You?

Yes, that's exactly what I did too.

 

[pakisatan123]

Yes, that's exactly what I did too.

no it was 1080000

 

[Dukeofwin]

no it was 1080000

No way!
Dont make us lose a mark!
Whats the procedure?

 

[17194]

manicooljay I'm pretty sure the answer to that was D.
<------------- electron flow
-------------> conventional current

 

[pakisatan123]

power into 60 x 60

 

[17194]

I got 1.08MJ too. I think both kWh and MJ are acceptable units.

 

[pakisatan123]

power into 60 x 60

because formula fr electrical energy is p xt and time in seconds

 

[pakisatan123]

I got 1.08MJ too. I think both kWh and MJ are acceptable units.

yeah see are ans are similar mine in joule but theres are totally different

 

[Dukeofwin]

power into 60 x 60

To be frank, i do remember converting hours into seconds!
Sorry shahryar 1 time to change parties!
Yup i infact did what pakisatan123! said!

 

[17194]

Actually we had to calculate how much energy was used. Both the kilowatt hour and the joule are units of energy. I don't think either answers are wrong.

do good in the atp. and hope the percentile doesnt go high.
i dont even know how my paper went. i did the whole paper but didnt get any feeling for it. :|

Actually you can count on the percentile to be pretty high, it was an easy paper and everyone seems to have done well.

 

[Minnie]

yeah.

yeah thats why im scared for it. i didnt get any feeling for the paper. thats
but still! We can hope for the best.
how are you studying for the atp? any tip?

 

[17194]

Actually im studying for chemistry instead. But the physics ATP is pretty easy. All you have to do is recall the lab work you've done. Anyways just do some past papers, I think that's the only real way to study for it.
