PHYSICS P 12. HOW WAS IT??

[alcoholic 111]

What does every one think the GT for the total A level physics will be? 188 for an A?

I Think 160/260 will make A

 

[creative22]

My doubts.
Question 2 : What was the result force of the 2 vectors ?

Question 39 : Was it Atoms or neutrons per at the rate of 100 something ?

Question 38 : there were Four graphs It was sort of complicated !

there was a question in which we needed to tell the mean power from the graph ?

what was the tension in the Picture that was hanged ?

Question 20 : dont remember the question options were like 3.4 x 10^6 , 3,4 x 10^9

What was the graph of skier that jump ?

What was the order for the diffraction grating ?

what was the answer that 2.5MHz radio waves or microwaves?

What was the graph of systematic error?

What was the answer of the electricity question in which different switched were opened and closed

When piston was compresses was it 80 J or 8.0 x 10^6 J
I converted cm^2 into m^2 and cm in to m answer was 80 J

39 mine is wrong i think cuz i did A
38 i did 250 the C
tension was 97 i think in hanging
graph of skier was becoming zerro and then increasing C i guess
order i guess 9 cuz it was 4.8 = 4 +4 +1 = 9

what were ur answers?

 

[geek101]

The kinematics graph question the one we had to covert velocity/time graph into displacement/time graph was repeadted

and that runner in the race one, though it was phrased a bit differently i think

People I have a couple of questions i would like to ask.
The question in which we had to derive an expression for the efficiency, was it B PSN/MG ?
What was the graph of the ldr?
What was the value of the diffraction grating? The screen was 180 degrees so did we have to like multiply the number by 2 ?
And the question in which we compared ice and water at 0 degrees. was its answer option A ?
Also the graphs of two materials were given and we had to tell whether they were ductile or britle or something like that. What was its answer?

I dont think the tension was 97 as there were two strings so tension was divided in both making it 48

I dont think the tension was 97 as there were two strings so tension was divided in both making it 48

it asked about the string... and in the question it said that its supported by 'a' string... thats what i think..... this mean that one string was divided into two parts... we had to calculate total so it was 97 ..... thats what i think...
please correct me if am wrong

Youve got a point there.
But i remember doing a similar question in the past papers and the value was half of what i calculated so i just went with that.

so what was ur answer?

Oh and would you answer the other questions ive posted up there

 

[geek101]

so what was ur answer?

4000

what about other questions?
the floating object one?
the moments one?
etc

isnt dat supposed to be 2Tcos65=mg??

Which one i dont remember?

efficiency one was A
graph? i dont remember? the flashing light one? it was B i guess
ice and water? i think i did D ..... dont know whats correct though? why did you do A?
i wrote they have same tensile strength of option similar to that...

what were ur answers?

for the efficiency i got A too. and for the floating object one, i chose the viscous drag is zero, cuz it was stationary :/

Efficiency B, Graph C I guess and uhh I think your D for ice and water one is correct.. and I did the graphs as both substances brittle i guess.

 

[geek101]

Efficiency B, Graph C I guess and uhh I think your D for ice and water one is correct.. and I did the graphs as both substances brittle i guess.

for the graph i chose the ultimate tensile strength is the same, for brittle materials the graph it a straight slope and then sudden fracture, but one of the graphs was a curve...they were breaking at the same force though so i chose that

Yeah but the graph was Force extension right ? If yes so the extensions would be different making different values of stress ... but if stress vs strain graph then youre right

 

[Silent Hunter]

and the moment one? having a beam and loads on it?
and the average power?
and the ratio one? what was the ratio wich said smthng about twice the young modulus etc?
