well, obviously... bt i meant tht since the ques is not asking 4 a graph, why do u want it??No i want to know how to make the graph. Lol
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!

can you please help me in how to answer questions such as exam 9709/32/O/N10 the question 8 part b
its basically after making partial fractions...expanding it to ascending powers upto x^3 etc
how do you do these? plz help
can some one please help with this pleaseee

why is 9810 not -ve? i mean shouldn't it be -9810??I remember tht...kinda tough, hold on.
pressure = density * g * height
pressure in the hole = 17.5MPa = 17.5 * 10^6 Pa, which is a result of the pressures of both the liquids p1 n p2
So, P(hole) = P1 + P2
17.5 * 10^6 = (d1 * g * h1) + (d2 * g * h2) ------> d1 = density of water = 1000kgm^-3 h1 = 2000 - x m
d2 = density of oil = 830 kgm^-3 h2 = x m
17.5 * 10^6 = [10000 * 9.81 * (2000-x)] + [830 * 9.81 * x]
17.5 * 10^6 = 9810 x + 19620000 + 8142.3 x
x =1271 m
salamz plz help wid dis qs...frm m/j-10-43...qs 4(c)

thanks alot for your replyokay look, if you reduce the wavelength of the incident radiation, the energy of the photon increases (since energy of the photon is inversely proportional to the wavelength).
This will mean that each of the photons will now be carrying more energy. So, inorder to maintain a constant intensity, the rate of arrival of the photons on the metal surface must be reduced.
Therefore, the rate of emission of the photoelectrons will be reduced. (Photoelectric current is the rate of emission of photoelectrons).
Hope it helped.
