make it 60

Wave was stationary and longitudinal?

 

[Musab100]

did anyone get power=41w and pq =.18m

how u got PQ 0.18 ??
mine was 0.09

 

[Musab100]

ya mine too

 

[rabos1]

ya mine too

Weren't there five complete loops indicating transverse? Are you sure its stationary, since there was no ovrrlaping of two identical waves and no resultant wave was produced which remained stationary...

 

[Musab100]

P= Current square x Resistance of two wires.

i added all the resistance in series is it correct ??

ohh sorry i also wrote transverse and progressive !!
and its right !!

 

[Musab100]

what was the gt in may june 2013??

39

 

[rabos1]

ohh sorry i also wrote transverse and progressive !!
and its right !!

You're wrong.. everyone wrote longitudinal and stationary.. are you sure it was progressive and transverse? Can you explain?

 

[Musab100]

i got 120m

120 is right
my was 240m but i forgot to divide by 2 because it was the total distance that wave travelled from source to reflector and back to reflector.

 

[Musab100]

look A moved a distance of 80mm in stationary wave there is no movement of particles. secondly the motion of A was normal to the movement of wave !!!! so its transverse

Oh they mentioned wave travelling from source to reflector? Then why do you think its progressive and transverse, Pl explain?

Oh okay, thanks!! Do its stationary and transverse?

that was different question !1 question 2

 

[DumbIdiot]

the wave was progressive and transverse as (according to the diagram) it hadnt reached the other end yet meaning that there was no reflected wave. A stationary wave is formed when the reflected and incident wave superimpose.

transverse

Thankyouuu!! I wrote progressive and transverse too... Feel a little relaxed... I think, I should forget paper 2 and focus on other papers...haha I couldnt solve 2.. you're a genius if you managed to solve it.. my paper 2 was just average.. I hope I do well in paper 1..

Can the force on the wheel be air resistance?

 

[100]

can the two forces be weight and drag of air?

 

[rabos1]

can the two forces be weight and drag of air?

Forces were normal contact and weight..

what were the 3 points for the alpha beta particle question
1 was because of mass
2 cause of charge
what was the 3rd 1?
