which ppr??What would be the graph?
We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

Q6 (b) (i) State and explain the polarity of the pole P of the magnet.
How do you figure this out? :s

Please help me with qn no. 6(b)(ii).. I'm totally confused!
Thans
Thanks..The phase diff is 180 as only when the two waves cancel each other out will a dark fringe be formed -----> http://www.s-cool.co.uk/a-level/phy...it/diffraction-interference-and-superposition
On it...Thanks..
And what about part 2, the ratio question?
can u answer q .5 b(ii) from physics coursebook exam style questions page no 118On it...
okay, so max (light fringe) amp = add the 2 amps (A + B) = 2+1.4 = 3.4 units
min amp(dark fringe) = A - B = 2-1.4 = 0.6 units
n since intensity is proportional to amplitude^2
thus, (3.4)^2 / (0.6)^2 = 32
Hope u gt it!!
which bk??can u answer q .5 b(ii) from physics coursebook exam style questions page no 118
cambridge internation as and a level coursebook from david graham jones richard and chadhawhich bk??
could u just confirm answers i got density as 666.7 and pressure at L as 4578which bk??
Oh yeah! ThanksOn it...

I just interfered!can u answer q .5 b(ii) from physics coursebook exam style questions page no 118
u just helped thanks man i just wanted answers thanks anywaysI just interfered!
For b(i) 800 × 0.5 × 9.81 = ρX × 0.6 × 9.81 [1]
ρX = 666 ≈ 670 kg m−3
= 666 kg/m^3
(iv) ρhg = 666 × 9.81 × 0.7 [1]
pressure = 4580Pa
Your answers are correct!
What would be the graph?
which ppr??
Can you please help me with this? https://www.xtremepapers.com/community/attachments/23499/
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
