How was Physics P42

[dadufahad]

So how was it, i found it easy, Alhamdulilah it went well. GT may be A=62-64

43 was quite tough..lucky guys..

The electrons didn't emit in the quantum question last part?

And what happened when sampling frequency increases and longer notes instead of short notes?

what were the two faces at which force was experienced ?
and the part below last part of the magnetism part?

And how where we supposed to link the internal energy of ideal gases with reference to assumption of gases?

The electrons didn't emit in the quantum question last part? - Nop cuz photon energy < Work function

And what happened when sampling frequency increases and longer notes instead of short notes? Didnt put anythin

what were the two faces at which force was experienced ? Forgot wat i put
and the part below last part of the magnetism part?

And how where we supposed to link the internal energy of ideal gases with reference to assumption of gases? There exists no intermolecular forces of att. b/w molecules of an ideal gas. Ideal gases have no P.E. Thus it can be defined as mean translation K.E of all the molecules of an ideal gas.[/quote]

Increasing sampling frequency decreases the step-depth. Thus accuracy of reproduced signal is improved.
Using a larger number of bits decreases step-height. Again, accuracy improves.

Derive using gravational force = Cent. Force then x1/2

I did get change in kinetic energy as far I could remember was 1.0 x 10^8 J But then after retrying i got another value.

Hey do you remember your value of kinetic energy?

I dun :S but first time I calculated I got the 1.0 thing but I rechecked thrice it wasn't the same :S I hope i didn't made a mistake there :S

there was no Km, radius was in m.

It was in Km guys !!
just wait for the marking schemes you will get to know

i have a concern. Please help me out. If for example, your gradient is 127 118 and your absolute error is 30 946.......than how should i write my final answer with the error?????

I don't think errors can be taken to more than 3 s.f. So it would be 127000 +/- 31000.
Personally i would prefer to write it as (12.7 +/- 3.1) x (10^4)

dont you write errors to 1 s.f.?

 

[Taci12]

dont you write errors to 1 s.f.?

Camdrige accepts 2 s.f for the graph especially

one more thing.....how do you draw a hall probe?

A small blank square connected to voltmeter

A small blank square connected to voltmeter

Do you have to connect it to a power supply?
