I think # 10 is actually B by virtue of the fact that there is a loss in G.P.E and a gain in K.E ..... and He cannot have G.PE if he is already at the bottom of the hill
hello good day i was wondering if you could give us a chance to answer the question before giving the answer in future videos. i learn better that way and although this is my last exam there might be someone who learns better that way as well.
it is not B the reason for this is because it started off by saying the person is moving down the hill if they said the person was stationary before coming down the hill then it would be potential energy but because he was already moving kinetic energy is gain until he stop at the bottom of the hill and then it become potential energy since all objects have potential energy but it would be lower compare to when he was on the top of the hill
Sir #21 is actually D: Specific heat capacity

Isn’t 21 D?
That's right. Brain fade there lol
Thank you so much. This helps alot!!
You're welcome, good luck
Thank you
Thanks
In number 7, if the y axis is distance, wouldn't the answer then be A?
I'm confused now but maybe it's not given that 10m/s is the initial velocity.
another vid said it was A
Its an acceleration graph , the y axis is velocity
@@caseysmith374 how do you know that?
Thank you sir🙏🏾

yeah, it's actually like studying when you do that, as opposed to muscle memorying some questions,
truer words have never been spoken
Much appreciated!!! Wish me luck!
Best of luck!
Isn't 30 A since x ray wave length is smaller
Decreasing order means longest to shortest
Hello, how can I get access to the physics papers??
In question 10, since they are going down a hill wouldn't they have G.P.E causing the answer to be B?
He was already riding down the hill in the beginning of the question, so we have to begin with kinetic energy.
Got an exam is 30 mins lol
using the formula for number 28 gives 1.95kpa
Which year paper is this
2012
I believe 10 is B
it is not B the reason for this is because it started off by saying the person is moving down the hill if they said the person was stationary before coming down the hill then it would be potential energy but because he was already moving kinetic energy is gain until he stop at the bottom of the hill and then it become potential energy since all objects have potential energy but it would be lower compare to when he was on the top of the hill
@@justpojo there is a change from GPE to KE ... It MUST start with GPE.. As he continues diwn the hill the GPE chnages to KE
