Physics: Post your doubts here!

[hellodjfos;s'ff]

Ok what I did was, I used my ruler as the spring board and put one pencil below the rule and the other one above the ruler. That's how I understood they had moment in the opposite direction. You can test i out right now, use your finger as the spring board(if you want).

And I kept the center of the springboard the pivot so that the weight of the springboard would be taken out/ruled out of the question.

Shit. I put A for the 1st one but C for the 2nd .. :'(

What about the displacement time graph for the man jumping from a rocket/ helicopter. His velocity time graph was given

It had a hill shape.

Heyy someone please help with qns 5,19,21 and 31

It had a hill shape.

There was one with a hill and i think that was no 5
But there were other two graph questions, one projectile one. And one another. I am talking about the other one..

Tell me a few details about the question?

 

[zap-cannon]

The velocity time graph was like a curve, which became constant after some time. Does it ring a bell ?

 

[Kanekii]

The projectile one had straight/constant velocity graph right? The parabolic stone one.
I screwed up my papeer.

I think it was A

 

[Kanekii]

What about displacement graph?
For the increasing straight line velocity and then decreasing was the displace time graph for it two opposite triangles?

All physics papers went good untill p12 what a great way to ruin summer vacations
Btw what have you guys planned for summer vacations?

 

[dwightedknight]

I'm going to cry all vacation.

Btw moment one with rods was both decreases. I can prove.

hey....what topics were tested heavily so that i can prepare for my p11?

 

[zap-cannon]

These are the graphs I put..

Yup I got these.

 

[zap-cannon]

The last graph... its A right ? I just dont remember what option i put but iam pretty certain i put this one.. but there was another one very similar though. So

Don't remember the option either

Remember all graphs of v, t, a, F there were like 4 questions regarding graphs
Electricity
Wave

Shit i screwed up first two graphs

 

[Kanekii]

What was the answer of the pressure question
Was it (p-p) A
Something

 

[Kanekii]

Y

Don't remember the option either

Yes it was A i remember.
