It's 14 billion years haha, that one was defineltely wrong.

For question 15 Multiple Choice I put E, The reason for that is because doesn't the ball starts off at rest with so speed and then gradually it gets faster and the acceleration increases ?

Im guessing Im incorrect by the amount of people who chose something else but can someone explain why ?

For Q20 Multiple Choice, IM SO ANNOYED WITH THIS ONE, I THOUGHT IT SAID 14 BILLION

The ball does start from rest but it is already moving by the time it gets to P and then it starts accelerating more from P to Q. I thought it said 14 billion too :frown:

According to my friend it's 14 Million....

He said he sung the big bang theory theme tune in his head and apparently got 14 million... Can someone clarify by googling the big bang theory theme tune :P

Yeah same, i got a recurring decimal as well.

All i remember is, is that delta t was 25 degrees if i'm not wrong?

Edit: 25 degrees


Can't remember what delta T was but I did get a recurring decimal for part B and I got part A which was prove the specific heat capacity was 627000 or something similar

Yeah part a was to prove it and I got the recurring decimal in part b as well :smile:

Part b was the power output question I believe
i am so stupid ....

What did everyone put for 11 M.C ?

It's definitely 13.8 billion so approximately 14 billion. Can't believe I mucked that up, I have known that fact for years...

B.

I was confused between A and B
What has everyone estimated they got in M.C \?

Look at the bright side tho, it's only 1 mark. Still got another 109 :P

If @ScottishGuy and @Marina1264 answers are correct.. Then 19/20
What do you write for the opened question ?

1. About the teacher and waves in a pond

2. Aircrafts taking off

If the pictures are to be trusted then 19 or 20 /20
So if multiple choice is out of 20
Written paper is out of 90
Assignment is out of 20

So the whole paper is out of 130 so for an A I'm assuming you need approximately 90/130, yes?
