ALL CIE PHYSICS DOUBTS HERE !!!

[astarmathsandphysics]

pretty bad to lose marks for using whatever you want, but if you use a pencil you can rub out a mistake.

Can anyone help me with question 13?

Thanks, SkyPilotage. I did see your post but 45 mins before the exam so had to rush

I was talking about the other subpart for q7. But its all cool. You're a life saver

What m i suppose to study for practicals

What m i suppose to study for practicals

you need to learn what to do while your practicals and be accurate
don't make mistake in the uncertainties
and
enjoy your practicals

Question 9 and 12

Pls Show the working

Thanks

Question 9

Use the formula :

Final velocity of second Ball - final velocity of first ball = initial velocity of FIRST ball - initial velocity of second ball.

Make sure to use the VELOCITIES and not the SPEEDS.

It has practical stuff on it

thanxx but a bit late

Can someone please tell me how we could find the frequency of a wave using a cathode ray oscilloscope???

And tell me how the the answer to Question 5 in http://www.xtremepapers.me/Edexcel/Advanced%20Level/Physics/2010%20Jan/Edexcel%20Physics%20Unit%202%206PH02%20January%202010%20QP.pdf  (January 2010) is 50 ?? 


Thanks xx

Thanks xx

The time period of the wave is 20ms (4 blocks)

20ms = 0.02s
Frequency = 1/0.02 = 100/2 = 50Hz

Guys...could you help me out with Qns 11, 19 and 36...It would be awesome if someone could give me a detailed explanation... cus im just not getting it
Oct/Nov 2002 By the way...

11. Gimme some time
19. KE (original) = 0.5mv^2
v^2 = 2as = 3920
therefore KE = 1960m

40% loss = 40/100 * 1960m loss = 784m loss
Thus, remaining = 1176m

1176m = 0.5mv^2
v = sqrt(2*1176) ~ 49

36) Total resistance = 1/(1/15 + 1/15) = 7.5ohms
Resistance between X and Y = 1/(1/10 + 1/5) = 10/3
VOltage = (10/3)/7.5 V = 2/3 V

Which formula did yu used
