PHYSICS P 12. HOW WAS IT??

[Equilibrium]

Oh and about the uhh graph in which resistace of x an y givin. that was C yeah ?
Power in X = 2 x power in Y... when in series ?

 

[Equilibrium]

average power 250
Beam one was D i guess I dont remember exactly but two foces were acting on left one at distance 2 and the other at 4
ratio one was 1/2

 

[Equilibrium]

Oh and any ideas on the GT ?
I say below 28 for sure. This was the hardest paper ive done and ive done almost all of em

what was the answer for volume of wire?
and the resultant vector one ?
and the ans for q40, was it Al and gamma?

 

[geek101]

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

i think they mentioned that the wires had the same dimensions, which makes the cross sectional area the same.
The graph i think was a force extension graph, and stress = force / cross sectional area so from the graph the force basically tells you about the stress on each wire (since the areas are the same)...??

power one was C i think....

Al

What volume of wire?
Vector one was the one going right and slightly down
and Q 40 D al and gamma

What volume of wire?
Vector one was the one going right and slightly down
and Q 40 D al and gamma

the one in which the diameter was given in mm
question 5
using meter rule, micrometr and vernier.c

B Micrometer and meter rule

 

[Alice123]

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?

the moment one was A i guess

 

[Silent Hunter]

what about the one having 0.5 sec drop time etc and asked about height of tube?>

 

[Alice123]

what about the one having 0.5 sec drop time etc and asked about height of tube?>

i dont remember da qs, prolly it was A

 

[Equilibrium]

i dont remember da qs, prolly it was A

Yeap A, 130 cm

 

[liu ling]

was the acceleration 1.1? from the v-t graph question
the wave, radio or micro?
frequency of the stationary wave in the tube?
ans for the question in which a hand was supporting a block with 2 newton meters attached
and also, ans for the piston and compression of gas question

 

[liu ling]

its

i dont remember da qs, prolly it was A

is it the same question as in s12/11 q8?

 

[Alice123]

its
is it the same question as in s12/11 q8?

nope

 

[Silent Hunter]

Yeap A, 130 cm

what is the reason for A ?

 

[.cookie.]

[Equilibrium]

what is the reason for A ?

They say time is around .5s so we use the formula s = .5a(t^2)
a is 9.81 and t is .5
