i think hoepfully 80-85% and p2 to save it

did area under the graph, rectangle + πr²/4 got something like 3483m?

Yh I got like 3500 smth around that but I didn't use pi r squared

It wasn't awful but the whole last question was awful and the energy transfer ticking. What did u guys say for differences between a red giant and white dwarf

i said size and temp
then no clue so just talked about them

How did u guys do in the non-regional paper??

Why was the piece of iron attracted to the bar magnet? What lines where you meant to draw? I just said because its in a magnetic field so has been temporarily magnetised but i think that isnt it and i free styled all the lines with no idea

That’s completely wrong, acceleration is not constant

exactly i thought u have to work out area under graph bc acceleration changes the graph is curved not straight

is wave B TIR? for the 6mker

No because it moves from less dense to more dense and tir only happens in more dense to less dense

Yh same I also said like smth abt hydrogen running out vs helium fusion running out idrk but size and temp is right I think

I'm not sure a few of my friends did that but I did both was refraction bc I thought for tir it needed to be from a more dense to a less dense material and it was going from air to water so

Ok that's what I thought so it was both refraction right?

but TIR can occur in glass semicircular prism

Yh i got something around 20 for A and around 40 for B i cant remember (for angle of refraction)

I have no clue what that was lol I guessed but I'm p sure my friend said smth abt temporary magnet

I did area under the graph and got smth around 3500

Yeh I got 36 and 59 for incident then 26 I think and 40

i got basically the same thing thank god

oh so it isnt tir ☹️ how can 6 marks be done for the identicla thing then!

Yeah I was confused abt that asw but they probs give like makrs for stating simple things like the equation or smth and also marks for adding to the diagram
