A2 level ?I don't understand mark scheme for drawing the circuit. Can anyone help me with drawing that and i don't understand why the terminals of external circuit is attached to the earthing.

Q6b (ii)
Why is there a potential difference between face BCGF and face ADHE ?? i don't get it
Q11 b (ii)
Yup it's about relays and diodes.A2 level ?
So much to study in A2 level... I am in AsYup it's about relays and diodes.
Haha don't worry! A2 is difficult but if you set out a routine and study accordingly it will be a breeze! I have to give two full a levels (chemistry and physics) and two a2 levels ( bio and maths) this may june but just started preparing today! quite worried! How about visting my new chat thread to share your anxietiesSo much to study in A2 level... I am in As
14- the direction of force would be opposite to the direction of field. one way to think about it is that as F=eV/L and e is negative the force will be in opposite direction. or you can think that the electric field shows the path taken by a unit positive charge so electron, having opposite charge, would move in opposite direction.
18 part was a bit confusion, but it is cleared. Ty14- the direction of force would be opposite to the direction of field. one way to think about it is that as F=eV/L and e is negative the force will be in opposite direction. or you can think that the electric field shows the path taken by a unit positive charge so electron, having opposite charge, would move in opposite direction.
the direction of field at that exact point would be tangent to that point. so clearly A is the answer.
16- alpha particle has a positive charge and so does a nucleus. so the alpha particle and nucleus repel each other. the alpha particle closer to the nucleus would bend more and alpha particle away from nucleus would bend less but both will bend away from nucleus. so answer is B

Physics as level notes neeeded PLZZZZZZZZZZ anyone ????
Best notes
20- take readings of current at zero volt and take the ratio
ans is a A broAnzuman turin
26- the circumference = distance travelled by one point charge in one round. frequency means rotation per second. there are four of the point charges. so total charge pass in one second will be 4 X (2πr) X Q X F=8πrQf
got it . thanks for the help bro . please help with other questions when you are okforgive me i didn't sleep last night and i don't know what i am saying. i confused it with the question in which the distance was found for work done.
I don't know why i multiplied distance.
charge per point = Q, charge pass per round=4, round per second=f
A=charge/time=charge.frequency while charge being 4Q
giving us 4Qf as final answer.
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.
