It was soon difficult.

How did it go for people finding hardest ever math p22 paper piss easy?

Paper was kinda tough and ok at the same time.
Wasthe displacement time graph like this?

That was the speed time graph shape for one of the questions. The displacement time graph for question was a reflection of this graph you made

Paper was relatively easier to previous summer papers. There were many repeat questions...

Which questions were tough for you?

 

[Mts.99]

What was the shape of graph of semi conducting diode?

 

[hellodjfos;s'ff]

What was the answer for the elastic energy per unit volume? I know it's a repeat question but I forgot the answer for it

 

[hellodjfos;s'ff]

What was the shape of graph of semi conducting diode?

The answer was B. It was the shape of a filament lamp(when it's an IV graph).

How did I guess that

That energy per unit volume answer was D?

Yup I got D as well. Thank god because I didn't have much time to do that question.

 

[Psyvlone007]

I guess it was D of that .and diode was B .btw what was of that Q6 which involved that a rock omis thrown on moon?

If you're talking about the vertical and horizontal force one, it was C(zero horizontal force, constant vertical force).

 

[Psyvlone007]

yeah that was kinda easy But I fooled my self at that time and Did that Non Zero and Constant hotizontal force

What about the moments question. The rod p and q one
and what about the stationary wave problem. A node at P. what are the wavelengths of the first five stationary waves?

 

[Psyvlone007]

A for that stationary wave . And Both decrease if that. Rods moment. what was the ans of that greatest current across battery that involved diodes

 

[hellodjfos;s'ff]

What about the moments question. The rod p and q one
and what about the stationary wave problem. A node at P. what are the wavelengths of the first five stationary waves?

A for stationary wave(the option with first wavelength being 2L/1). B for the rods moment question since one rod has a clockwise moment while the other rod had an anticlockwise moment(weight of the man had a clockwise moment which was decreasing since he was getting closer to pivot).

 

[hellodjfos;s'ff]

I can't remember the option but it was the diagram with a parallel circuit in which the direction of the diodes was same.

Brother i think that Moments one was Both Decrease Because i had studied that Rods had Both A single direction of motion .

 

[zap-cannon]

Shit. I put A for the 1st one but C for the 2nd .. :'(

Brother i think that Moments one was Both Decrease Because i had studied that Rods had Both A single direction of motion .

What about the displacement time graph for the man jumping from a rocket/ helicopter. His velocity time graph was given

 

[hellodjfos;s'ff]

Brother i think that Moments one was Both Decrease Because i had studied that Rods had Both A single direction of motion .

Ok what I did was, I used my ruler as the spring board and put one pencil below the rule and the other one above the ruler. That's how I understood they had moment in the opposite direction. You can test i out right now, use your finger as the spring board(if you want).
