Physics: Post your doubts here!

[ZaqZainab]

Thanks a lot, but I was wondering that in the first question had mentioned 2 marker posts so shouldn't s=(100*2)m?

It says when it passes 1 post it has a speed of 10
so we take the initial speed as 10 and the 1st post as the starting point now how much are you traveling afert the first post? just 1 more post you getting it right don't consider teh distance between the 0 post and 1st cause that not even counted you don't even know the speed at 0 post so that's why 1st post

Ans is C.. The period of the wave is 60 ms.. Count the boxes.. the actual wave completes in 6 boxes.. Now u need to find the option in which the wave completes in 60 ms.. Its only in C. Wave completes in 3 boxes, each of 20 ms, hence the period is 60 ms
