how was physics p22?

[Muhammad Haris Ghani]

second part was 0.2 s/cm and distance between PQ i got it 0.089 m

I got exactly the same answer what was your speed for the wave my was 7.5 ms

 

[Muhammad Haris Ghani]

What u wrote in waves
Stationary or.progressive ??
Transverse or.longitudenal ??

progressive and transverse no doubt

 

[Muhammad Haris Ghani]

what your speed for the wave

 

[Musab100]

progressive and transverse no doubt

Some.people are saying it was.stationary
And what was yr.distance in cro question

 

[Muhammad Haris Ghani]

I also do think it's a stationary wave in the same way being a transverse one also>> Is it??

yes it was progressive and transverse

 

[Muhammad Haris Ghani]

And what was yr.distance in cro question

first tell me what was your speed for the wave

 

[Musab100]

first tell me what was your speed for the wave

I didnt remembered that part
What was given ??

 

[Muhammad Haris Ghani]

What about forces on wheel? I wrote weight and normal force and that it is not in qequilibrium cause of the torque is that right??

it was in equilibrium because both the opposite forces were cancelling each other what was you speed for the wave

 

[Muhammad Haris Ghani]

I didnt remembered that part
What was given ??

yar 1.5m wavelength 1 oscillation in 0.20sec and we were tolled to find the speed of the wave

 

[Muhammad Haris Ghani]

what was your answer for the question 2 my one was 0.05m and i think it is 90% correct and yours

 

[DumbIdiot]

what was your answer for the question 2 my one was 0.05m and i think it is 90% correct and yours

question was about the pulse right?

if so most got the distance = 120m

 

[Muhammad Haris Ghani]

question was about the pulse right?

if so most got the distance = 120m

no its too high what was your answer for the speed of the wave mine was 7.5ms

 

[naoomi]

for ques 2. the answer to the second part was 0.2cm/s . I could'nt do the first part. and for the wave I wrote progressive and transverse and shifted the wave to the right where they asked to sketch. Many say it was stationary though

yar it was progressive

speed 7.5 yea but the distance 120m is probably right.

speed was 3x10^8ms and time taken for wave to travel from initial point to reflector and then back to initial point was 0.8x10^-6 s . v=d/t ---> d=240m. distance of reflector from initial point = 240/2 --> 120m

 

[blah4023]

I'm gonna get an A* in the paper Wohooooooo!!

Kidding, hope I manage to get a C/D

Love, A* is not possible as it is. The highest grade in AS Level is A

And, I will hopefully get a B. Praying to the mighty God, cos if not, then I might as well be dead.

Ohh acha that my answer was 7.5 i am sure
What was yrs

 

[Musab100]

what was your answer for the question 2 my one was 0.05m and i think it is 90% correct and yours

Why its so less ??
My was 240

 

[Musab100]

speed 7.5 yea but the distance 120m is probably right.

speed was 3x10^8ms and time taken for wave to travel from initial point to reflector and then back to initial point was 0.8x10^-6 s . v=d/t ---> d=240m. distance of reflector from initial point = 240/2 --> 120m

This IDIOT is right i was also gettinh 240 hm but forgot to divide by 2 but m sure i will get marks
