What was the answer for the alpha particle deflection?
Because i couldnt see the mentioning of large angle, im kindda confused

It was mentioned... Answer was volume of nucleous really small... Because others werent making sense...
What about the uncetainity qstn... What percentage u got there?

 

[afrolina]

My questions:
3. what was the ammeter related graph
4. was resultant vector thing D
6.uncertainty question..was it 6.67
then, change in gravitational potential energy-400?

gain in energy of fish pulled up-> was it only gpe?

waves question was phase difference 150 and length 1.1?

what was the resistance extension graph??

Well, i answered that as well, but did they say it delflected by large angle?. The uncertainty that i answered was 6.7 but i think the answer is 4

Yea he said large... Its a repeat question and I saw the ans in past ppr
Btw i dunno what it was but many said it was 4%

3)a 4)C 6)4 hen, change in gravitational potential energy-450 , gain in energy of fish pulled up- gpe+Ke , length 1.1 , resistance extension graph -A

FOR BALL thrown horizontally in moon , Horizontal force=0 and Vertical force=constant Action and reaction . THe push of table on book. (D) Width is 2w DO anyone know the right answers for this question

 

[Choi WW]

The wave, phase difference was 260 wasnt it?

 

[Choi WW]

Also, there was one question asking for how should the systematic errors of height and time to vary to find gravitational acceleration, right?

Did they ask for the value greater than gravitational acceleration or just exact?

The answer for that question was D, as a shorter measurement of time suggests a greater value of g

I think it was A

CRAP! I think i did large value of t =(

For the fish question, when they asked us to find the gain in energy of the fish, its actually only the gain in gpe. Cuz the velocity was constant so there would be no change in kinetic energy.
