yes pretty much high according to these thresholds

Oh wow!

 

[Rizwan Javed]

So generally u give in parts or all together, there is no much difference in GT?

Yes, not much difference here but sometimes there is a great difference, like if you see the gts for 2016 May/June Chem, the A* for those who gave all 5 papers together, the thresholds was in 170s (I don't remember the exact figure) but for those who gave in parts, the threshold was high like in 190s! But it happens very rarely though

How do we know seprate papers gt?

look at what?

The gts for individual papers are given in the table at the start of the file for that particular year.

In this, where can i know that A* for paper is 170 or sth?

in this year, The gt for an A* if you give all 5 papers was at 191, where as for those who give in parts, the gt for A* was at around 180sth (depends on in which session you gave the AS portion papers)

Suppose one gave it in November 15 and scored 76 in AS level.
So in A2 he gave in may 16. What will be A* at for that person? like how much should he/she score in A2 papers?

Fleming's left hand rule for the motor effect. Magnetic field, Current and Force are at right angles.
Is the current considered from positive to negative (conventional current) or from negative to positive?

The seCond finger represents Current. Keep the second finger in a way that ur nail point in the direction of current.
When the particle is electron(-ve charged particle), we take opposite directions and when there is positively charged particle we dont need to bother about changing direction, keep the finger in the dirrection shown in the question. In wire as well, oint the finger in the direction of current.

could anyone explain the seeback effect??????

Which chapter is it from? I never came accross this word in whole textbook of A levle physics

Hey there, in the (a)(i) If I write that Fc = MR(omega)^2 as omega is same Fc will be same?

The one who upload notes, ask for more help from him/her.

Here we can only hep for physics though.

Q5(b)

 

[RICK SHARMA]

The density of air on the Earth decreases almost linearly with height from 1.22 kg m –3 at sea level
to 0.74 kg m –3 at an altitude of 5000 m.
Atmospheric pressure at the Earth’s surface on a particular day is 100 000 Pa. The value of g
between the Earth’s surface and an altitude of 5000 m can be considered to have a constant
value of 9.7 m s –2 .
What will be the atmospheric pressure at an altitude of 5000 m?
OPTIONS:
36000 Pa
48000 Pa
54000 Pa
59000 Pa
How is this done....been scratching my head for an hour now...
