physics 22

[I don't care]

bro ask your teacher he will make your concept clear and yes inform me as well

Bro i asked my teacher he said you are supposed to use the area under the graph which is energy. that is what i'm trying to say here. Area under a force vs distance graph is energy we know the total energy of the trolley which is 1.3 J

i
i agree.it was that easy

I agree that it was not that difficult but in what world do you really think that the threshold would be 57/60. Man use your brain and step out of your bubble

The only thing that can make a person think so is very highly concentrated Ethanol

LOL..... for your kind information my power was 41w and unit I dont remember now if you have guts tell me your answers

By the way what was your power and unit for C ....

 

[I don't care]

it was 41 W and i don't remember the unit for C it's been so long i forgot. Good luck in paper 1

thankyou bro but are you online

HAHAHAHAHA, it was the same, but confirm it from your teacher, maybe our answers are wrong, see I have the guts, unlike you.

Ohhh, I have conformed it, its correct now show some more guts and tell me your unit for C so that I may conform it

so what do you think the gt could be

you too best of luck

It was something kg^-1. I am not sure what about the whole unit. Don't worry haris, you will do good. We all will do good, inshaAllah no hard feelings.

 

[xand12345]

And yes what was your power for wires and your unit for C ....

kgms^2

 

[boredome]

guys i forgot to convert from micro seconds in the second question how much do u think i will lose ... and what were the 3 points in the alpha and beta thingy comparison ?and the Gt might be around 39

 

[boredome]

guys r u sure the wave wasn't a straight line ? coz i remember a similar question in june 13

 

[Ujjwal Basnet]

It was still super easy. May june too.

oh really May/june was super easy then why are you appearing in oct/nov again..?

I know its abit late but doesn't the basic principle of physics state that work is force applied into distance moved IN THE DIRECTION of force so keeping this in mind work done by force F should be zero since trolley never moved in direction of force F. Now I don't know how many of u would agree but this is something to be noted. Hence leaving no other choice but to use eq of motion n I know acc wasn't constant but we had to do something like take average force and acc. But W=f*d cannot be used in any case

i think this is called negative work.
positive work can be done to increase ek
negative work can be done to decrease ek

Physics was never so complicated
