Physics p21 mayjune 2014 FULL PAPER DISCUSSION AND DOUBTS!!

[Waqas Nasir]

How was your paper guys??? Share your answers and doubts so that everyone can make sure what they have done in their paper!!

 

[Waqas Nasir]

What was amplitude in the wave question? according to me i it was 15-12 and then /2! was it correct

yeah i guess 1.5mm should be right

 

[Yunus haji]

hey guys what was the frequency of the wave. I got 1.8 but most of my friends gout around 0.5 or something like that!!

 

[saadkhan97]

yeah i guess 1.5mm should be right

yes it was 1.5mm

 

[saadkhan97]

yeah i guess 1.5mm should be right

what was the answer to the moments graph question ? anyone ?

 

[MYLORD]

yeah i guess 1.5mm should be right

YES !!!
Thats what i got !!!

who is also giving paper 4 and 5

what was the answer to the moments graph question ? anyone ?

idk the graph part :/

 

[IGCSE O/L student]

what was the answer to the moments graph question ? anyone ?

the graph is a straight line with a positive gradient
i only remember one point, (0,100)

 

[Farouk123456]

the graph is a straight line with a positive gradient
i only remember one point, (0,100)

And meets the other line at distance x = 2.5

 

[Ram Ramiro]

The paper was easy, only the moment of force questions... they were confusing, does anyone remember the answer for the force of Fb?

 

[mahnor]

What were the direction of acceleration and resultant force?

 

[Waqas Nasir]

hey guys what was the frequency of the wave. I got 1.8 but most of my friends gout around 0.5 or something like that!!

none of these is correct. The real real answer is 1.5mm

 

[Waqas Nasir]

I am

[Yunus haji]

That was the amplitude. Then it asked you find the wavelength and then the frequency.

 

[Ram Ramiro]

What were the direction of acceleration and resultant force?

Yeah, even I have the same doubt... I did both of them to the left though, and u?

 

[Ram Ramiro]

Guys, also that car that moves at an angle, do I do F*VSin(9) or V*FSin(9)? which one is the right one?

 

[Autumngirl]

The second one. The answer will be same in both cases though.
