[@aunshah3836]

At 8:00 how can there be an "upward force"? The weight is downwards and when the 2kg object is released the acceleration for the 3kg object would also be downwards. I'm confused!!

[@YfenegReall]

I think upwards force here means the force of 3 kg object being pulled up

The answer was 8800s on 1b revise your work miss

[@munasheechakatsva6555]

On the last question no. 11(a)(i) how did you conclude that the gold nuclei is positively charged?

[@rishabhtalwar573]

It is because nuclei consists of protons and neutrons. Neutrons have no charge and protons have a positive charge. So the overall charge of a nucleus is positive.

can you please explain 2b in more detail

Correction 52:01 it’s 0.83 not 1.2

[@HannahThakkar-gk5iz]

The correct answer is 1.2 ohms as you need to reciprocal the 5/6 to 6/5 it's a rule for to calc parallel resistance.

[@pennywise3418]

is answer 2.16*10^6 in Q1 correct? why u take 2.2.

[@mariyakhan6873]

She just rounded off the value... Don't worry you'll still get the marks if it lies between the range

[@arraby8590]

wouldn't we use flemings right hand rule in Q7 C?

[@tanujaphatak7509]

right hand rule is used for motors

[@alsanasim344]

​​@@tanujaphatak7509that's actually the wrong interpretation, if we are passing the current through a magnetic field(as in this paper) , that in itself is the motor effect, and we will use Flemming's left hand rule, however if we are applying a force to a conductor within a magnetic field and yielding out a current then this is the concept of an ac generator and thus we use right hand rule.

[@xdSloshy]

@@alsanasim344u can use both rules dumbasses
