For q15 if u have done A level M1 then it will be no problem however this is the solution:http://www.xtremepapers.com/papers/CIE/Cambridge International A and AS Level/Physics (9702)/9702_s11_qp_11.pdf
help in q13, q15, q25, q27, q37
Magnetic flux linkage means No of magnetic field lines (Symbol: Φ )waalaikumassalam wr wb
haha...nice one
ok and for ques 6..i wanna know what's the difference b/w flux and flux linkage..see ms...it says smthng like that...
and jazakAlllahhhhhhhhhhhhh for the help...
many duassss 4 u
Aoa,
Q4
Q6(a)...some more doubts in June 2006
· Q:2 b (ii) how to do?? :s
· Q:4 c can you show, plz?
· Q:6 a what I understand is the field should be circle..right? I don’t get this :s
· Q:6 c what values do I use? :s
· Q:7
Magnetic flux linkage means No of magnetic field lines (Symbol: Φ )
Magnetic flux density is no. of field lines per unit area (Symbol:B )
Φ = BA
B = Φ / A
And thanks 4 the prayers, i really need them
Yes, i admit a little mistake of mine!I just wanted to point out,
Magnetic Flux is the number of magnetic field lines which is Phi.
Magnetic Flux Linkage is the product of the magnetic flux and the number of turns of the coil. which is N x Phi.
"Magnetic flux density is no. of field lines per unit area (Symbol:B )" like you said.
Thank you
Can someone please explain to me how to do question 18 and 20?
I kinda understand 18 my reasoning is that the pressure already in the flask is already hdg so in the increase would also be hdg giving 2hdg (correct me if i am wrong)
Can someone please explain to me how to do question 15, 18 and 20?
I kinda understand 18 my reasoning is that the pressure already in the flask is already hdg so in the increase would also be hdg giving 2hdg (correct me if i am wrong)
Question 18:-
Your reasoning for question 18 is wrong :S The change in pressure is denstiy (rho) x gravity (g) x DIFFERENCE IN HEIGHT (delta h)
If it increase by "h" on one side, it should go down by "h" on the other side so the change in height is 2h. Therefore, the pressure is 2hdg. i.e D
Question 20:-
Tension in P:- is :"T"
Tension in Q: - 2l means it is easier to pull so there is less tension ---> 1/2T
A/2 means its is thinner so its also easier to pull ------> 1/2T/2 = 1/4T
Therefore:- T/1/4T = 4/1 i.e D!
Hope it helped Feel free to post more doubts
For question no. 15Can someone please explain to me how to do question 15, 18 and 20?
I kinda understand 18 my reasoning is that the pressure already in the flask is already hdg so in the increase would also be hdg giving 2hdg (correct me if i am wrong)
Question 10:-Q 10 and Q31 with proper explanation.
Question 31:-Q 10 and Q31 with proper explanation.
Woops Sorry, I didnt see Number 15 in there Thanks for solving thatFor question no. 15
Since the water will be equally divided in both the vessels after the tap is opened so vessel X will now have h/2 height of water and m/2 mass of water.
Due to which potential energy lost= (m/2)*(g)*(h/2).
So, final answer will be (mgh)/4. Hence no. B
