how was physics p22?

[student013]

What were ur 2 listed forces acting on the wheel?

 

[Sherko]

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??

yes i wrote it the same!

 

[urvi kapoor]

I wrote progressive wave as they said point A moved 80mm

 

[student013]

was the wave transverse or longitudinal??

 

[student013]

I wrote progressive wave as they said point A moved 80mm

Point A acts like a vibrator, while point B is fixed!!

 

[walidbinkhalid]

what was the answer to the cro question?? the distance??

 

[kaka g]

Is paper discussion allowed prior to the 24hrs rules??????????? :O :O :O :O :O

 

[xand12345]

how much do you think willl be geade threshold for A

 

[Muhammad TAimoor]

It should be around 35, I hope

 

[urvi kapoor]

What was the amplitude

 

[Musab100]

What was the amplitude

I wrote 80mm

 

[Stud.Geek]

I m so worriedd! i messed up quite a few things!! what will be he gt!! i m so worried!

 

[Muhammad TAimoor]

What was the amplitude

Amplitude was 40 mm. A travelled a total distance of 80 mm and amplitude is the distance from mean position. Just divide 80 with 2 and thats the answer.

 

[Musab100]

Amplitude was 40 mm. A travelled a total distance of 80 mm and amplitude is the distance from mean position. Just divide 80 with 2 and thats the answer.

how u did that part in which it was to draw wave 0.05 sec later than shown ?

 

[Dark Blade]

Stationary or progressive?

 

[DumbIdiot]

Amplitude was 40 mm. A travelled a total distance of 80 mm and amplitude is the distance from mean position. Just divide 80 with 2 and thats the answer.

in 1 complete oscillation a moved from lowest to highest then back to lowest point which us equal to 4amplitude. Therefore the amplitude is 20mm.

Stationary or progressive?

the wave was progressive aa it hadnt reached the other end . A stationary wave is formed when the reflected and incident wave superimpose.

 

[RWTH]

I wrote distance 0.093. Because the previous question had estimated KE to be 1.3 whereas when we were solving it was 1.25. Any idea if I'll lose marks over it because I did use the same formula and the same answer as previous one given?

 

[kaka g]

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

Kidding, hope I manage to get a C/D

 

[Muhammad Haris Ghani]

I want to know the answer for question 2!
was it 240 m?

My was 0.05m

 

[Musab100]

My was 0.05m

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