How did u guyz do in phys p1 ?

hmm what was D?
I chose B, gradient of curve decreasing... (dunno ifits correct)
and spring constant was 200 man we had to find the gradient of line...(was ur p11)

Yeah, I think i knew now why the force is parallel to the field. I have just misinterpreted the question.
D was the first ball stops and the second ball moves with v.
Well i tried the spring constant several times and i got it 500 N/m and i did get the gradient. I took the first point and last one on the graph.
What about that power question of the resistor, was it 3 Ohms or 2 Ohms and that question of the density and spacings of water ?

2 ohm and density and spacing one i dunno:P
and i am pretty sure the ccordinates were (40,12) (100,0) // 40,100 were in mm and gradient is 200.
aw i did the ball one wrong :(
sloe:
I got 200N/m by finding the gradient using the coordinates given by A.T.. Im curious, how did u guys get 500n/m? And I dont remember the ques. abt. the power and resistors (the 2 or 3 ohm one). Wasnt there a ques. abt. a 24W battery (we had to find the power dissipated in resistor R iirc. there were 2 other resistors, P&Q). I got 4W for that one.
XaM!!:
NOOOOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!!
i got atleast 5-6 worong... :'( :'(

minimum is 0.
5N left and 3,4 N force on the right acting at 90 degree to each other
R^2=3^2 + 4^2
R=5
5-5 = 0 :D
charge can be stationary or moving and force is parallel to field
Ans i remember:
2.45 reading for screw gauge
neuclear reaction, neutrons conserved
2 masses stick v=10
P*V=energy
Q1 unit of volt ans was D
kirchoff one,conservation ofcharge
efficiency one was D mgsin/F
K=200 spring constant
A=1.3 acceleration
A doubled D double X remains same
5.5kw power
v=w/q e=w/q
and guys does anyone know the answer for the 2 same masses 1 station other collides with velocity V?

yeh the first one stops and the other moves to the right at a speed of v :D thats a repeated question :D
