Hey guys,
What did you think about the paper?
High/low grade boundaries?

Cheers,
PJ

Quite an easy paper. Could have been much worse.

It was alright, I guess. Hope for low grade boundaries...
Some questions were quite tricky
(I'm just going to watch TV now to wash away my tears lol)

It was on okay paper. Yes there were some tricky questions but on a whole it could have been a lot worse. Still praying for low grade boundaries though!

do you guys remember what you got for:

- the height h for the projectile question
- whether the boy's uncertainty of the angle (4+ or - 1 degree) was correct (the trolley question)
- capacitor graph

- capacitor graph
-2 point something idk
-no because i got 4.4 degree so difference is about 9%
-charging curve from the bottom of the square and then discharge curve at the end of the square. There are calculations but I don't remember sorry

For the height of the projectile question I got something like 2.3m. Couldn't do the degree uncertainty question but got a time period of around 0.05s for the capacitor graph.

The height for the shotputter was 2.2m.
Derivation of P=W/T was done using W = FdeltaS and T=2pi/w. Delta S is 2pi x r.

Distance thrown was around 22.5m

Equations 2 and 4 were not possible in the particle decay questions.

Angle Theta was either 4.31 or 8.43.
On the square voltage graph the capacitor dropped to 37% of its original value which is 1.85V. And the time constant worked out to be 5ms.

The small pond pump was the pump which should use the electrostatic motor.

The kg value for Lambda was 1.97x1-27.

that definitely was not it son. Asked my teacher he said it was 4.5

For equation 4 shouldn't strangeness must be conserved? The one which Lambda turns into a neutron

Get in!!! You failing will make my grade look better. WRONG

Why was it equation 1 and 3- it thought equation 2 which was wrong??

you're gonna need low boundaries

It would be a yes for the second one... it's uncertainty was in degrees, so if it was between 3-5 degrees, it would be a yes
