I can't remember the exact question but I know it gave you the milliseconds and your answer had to be in seconds, but maybe I'll get follow through marks? every other year they gave the conversion from seconds to milliseconds to you
Did anybody actually know the labels for the alpha scattering experiment? I definitely didn't 😂 I said polonium (alpha source) gold (one to two atoms thick and I made up sentegration screen, I still don't know what the right answers were
TA physics for the one about molecules moving etc. After the density, did anyone else put: NA Glass Water In that order in the boxes? Also for the equation connecting the bike question did anyone put:T-F=ma?

Just looked up the diagram, it was alpha source, gold screen and microscope... At least i got 1/3 haha
GUYS YOU aren't going to believe this. As a TA student I forgot the word for a ****ing microscope hahahaha. I put magnescope LMAO i'm so retarded **** me
and yes
N/A Glass Water
For the equation question what was the answer?
T=a(mxg+F) I put, didn't have a clue. I think it was T=MA+F

For the equation question what was the answer?
T=a(mxg+F) I put, didn't have a clue. I think it was T=MA+F
Was that the equation on the second page? I wrote T-F=M x A (Newton's second law factoring in friction?)
Anyone know how to get the constant forward force? I had no idea so just wrote a random number down to get follow through marks in the next bit!!
I did part iii) first and used the formula from the first page (t-F=ma) which gave you mass as 60kg, then i went back and substituted this into the equation again for part ii) which gave you 36N
What did everyone get for the last few centripetal force questions for TA physics?
I don't know about reducing the speed, I said you'll have more time to turn the car. For the radius I said increase to decrease the centripetal force. Wasn't sure on those explanations but they were only 1 mark.
For TA physics what did people put for the moments question and why it was not balanced?? I said it was because it had to be 56cm away from the pivot to be balanced but the ruler was pivoted at 50cm making it impossible to be balanced at that distance?
