Physics: Post your doubts here!
for 13, Forward force - Frictional Force = Mass*Acceleration Forward Force = 2.0*9.81 Frictional Force = 6N Mass (net)= 8.0 + 2.0 Acceleration = F-f/mass a=19.62-6/10 a=1.36 or 1.4 i.e A is the answer. --- for 15, since tourqe is equal to force*distance, the distance moved by the spindle will be... -

As it says, 3000 revolutions/min (apply unitary method) 3000 = 60sec 1 = x x = 60/3000 x= 0.02s(one wave) in the 10cm wide display of c.r.o looking at the options, the second one showing 10ms means 0.01 and 0.01*2 = 0.02 means one wave and when we multiply 0.02*5 (as there could be 5 waves made... -
A little confusing.
Greetings! hey everyone hope you're all doing good :) i'm doing A2 and just wanted to know what is the best way to hop into a uni, entry test or giving SAT? e.g for NUST.- emkay

A level Computing: Post your doubts here
as for A's, Yes you can. as i gave it already but for A2 you need assistance on the project as the CIE doesn't accept private projects. or you could just get it verified by some reputed school. -

for minimum force to be applied the angle is always 90 degree. and for second part, Torque = Force*distance Force=Torque/distance F=130/0.45 F=290N -

PHYSICS P 12. HOW WAS IT??
what about the polycrystalline and crystalline question? was it C or D? -
Physics: Post your doubts here!
for Q4 a ii) Ek = p^2/2m 1/2mv^2 = (mv)^2/2m (since, p=mv) 1/2mv^2= mv^2/2 (m and m cancels out) 1/2mv^2 = 1/2mv^2. (Hence, Proven) for Q4 b i) find change in momentum first, delta p = m*delta v p= 0.035*(4.5+3.5) p=0.28. F=change in momentum/change in time F=0.28/0.14 F=2.0N. -

sin theta = 40/50 theta = 53 F= 8Cos53 (Since, there are two components of 4N i multiplied it with 2, 4*2=8) -
Physics: Post your doubts here!
the torque between the pulley Q and P in the upper wire is the torque at Q. as it is causing the driving force for Q. i.e T=F*d F= T/d F=3/100*10^-3 F=30*2 (since, the formula suggests force into perpendicular distance between the two forces) F=60 N. Torque on P, T=F*d T=30*150*10^-2 (Force... -

you party crasher! :P why did you multiply it with 100 and made me look like a total idiot? :D -

How should we judge a person!
how about we don't judge at all? be care-free, easy come easy go. love nobody and feel no pain x) -
Laptop or tablet???
LOL. best of luck with the choice-making decision.
