Physics exam 2016 january ( 19/01/2016)

haha same.. i think i didn't do well in paper 1..

Nor do I.

I retain desire and optimism that if I can get 60 I will get an A*

oh yea, me too..

you know that q with light gates the average speed

did you convert the time he give you to s

and then divided the distance he gave you by it ?

Cant remember the question.

But I am fairly confident I got all the calculations right although there were not many of them :P

What about the last question.

What would you use instead of blocks, I put radiators?

wool because i think it will absorb the heat and keep it
is it right ?

what about the colour that have longest wave length is it red ?

and what is infrared can do burn skin right ?

and ultraviolet eye damage

maybe ah idk

I put red but I think it may be blue, since blue is dispersed more idk

Hmmn I said that infrared heat cells

UV heat cells which can mutuate DNA.

infrared is used in cameras and remote controls and **** so I am not sure if it burns skin?

i dont remember the q saied what infreared is used for

just one example for each and the q was about how it can harm you right ?

no they never asked what the use was just the dangers.

first 2 marks were easy.

transverse waves/same sp[eddd through vacuum

i wrote they all travel at the same speed 300 000 000

they all are waves
they all transfer energy

is it right ?

i put solar panels with matt black surfaces

Yes I put matt black radiatiors!

Not sure if it correct, originailaly thought matt black covers.

how did you do the directions on the diagram?

all upwards towardss the turbine and then an arrow down above the turbine, with the heat flow of convection

all upwards towardss the turbine and then an arrow down above the turbine, with the heat flow of convection

hhh
i only did the upward i dont think you have to draw a downward arrow
