The answer is C
There is constant phase difference along the line RS (Since the waves are coherent) and therefore, there will be no interference.
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!

The answer is C
Paper 12.
Q5:
x= 1.28-0.83 = 0.44
Error in x = 0.02 + 0.01 = 0.03
Uncertainty= 0.03/0.44 * 100 = 6.88
Answer D.
Q14:
Length of Ramp= 1.5/sin30 = 3m
Work Done against Friction = 150*3 = 450 J
Work done against Gravity = 200*1.5 = 300
total= 450+300 = 750 J
yar any one tell me about question 12

(11) Here is the equation for this question: F - R = ma.
Thank you and thnkss for your tym but i didn't understand ""moles = 3.29 (2x (14+16+16) + 16) = 0.03046 Moles"" what is this Mr isn't it total Mr of the two gases No2 and O2 which is supposed to be ( 14+16+16)+(16+16)=78 ??? pls answer and thnkss again
We add the 2 because there are two parts of wire with tention?
(11) Here is the equation for this question: F - R = ma.
F = The force used to accelerate the body
R = Resistive force (Friction)
m = Total mass
a = acceleration
The accelerating force is provided by the 2kg mass. Hence, F = (2 x 9.81) = 19.62N
19.62 - 6 = 10a
a = 1.362 m/s
(34) The starter motor requires a charge of:
Q = It
= 200 x 2
= 400 C
The total charge that the battery can supply is 100000 C.
So how many times can all the charge be drained from the battery if 400C is required for each start?
=> 100000 / 400
=> 250
Hope that helped

I will get back to you tomorrow. I have Physics P1 and need to work for it. I would be happy to solve any Physics questions anyone has. Just tag me.
Somebody please helppppppppp these are my problems don't have any link plsI will get back to you tomorrow. I have Physics P1 and need to work for it. I would be happy to solve any Physics questions anyone has. Just tag me.
