Physics: Post your doubts here!

Cool is it free?

I would have recommend you to play Paladins.Vry good game on both ps4 and pc but you don't have a ps4 .
I am going to buy Uncharted and God of war

I'm probably just going to sit in a corner and cry. I really need a C in maths and physics.

Dont cry

 

[A*****]

the last graph, shouldnt it have a curve at start? which was option C

Yes I did C too because from the start the velocity wasn't constant, it was increasing...it would have been A if the velocity was constant at the start

 

[zap-cannon]

It has to be A i guess. C was zero for some more time . Most of my smart friends in lahore have put A. Lets see though. C is also a common ans

 

[dwightedknight]

What was the last graph question?

 

[penny lim]

can pls help ques 34
ans is D but i don't know why

Hi
What is a mass of particle moving with a speed if light and why
Ftinite
Infinite
Zero
Unity?

It's complicated. First off, a particle cannot travel at the speed of light. But let's say that it's travelling very very close to speed of light. Particle will feel like it is travelling at very high speed. An observer will feel like the particle is stationary.

The option unity doesn't make sense because it's dimensionless.

So from an observer's perspective mass is zero right?

No it approaches infinity

Well I think that how the object appears depends on whether the observer is stationary or moving away from or towards the object
According to the theory of relativity, the object will appear contracted if the observer is stationary.

thanks

Tommorow is result xD

 

[Hisham Khan]

Because speed is same

Is anyone having any access to the grade thresholds for this session?
I hear they are out :/
