Hello All,
I was just checking magnetic field lines as in attached figure.
I am curious to see some gaps between adjecent field lines in the figure.
Why it is not like a sheath( for example in lighting field) but as lines?
Thanx in advance

Dear Sirs,
I am wondering what is the difference between v=s/t & dv = ds/dt where v-velocity,s-displacement,t-time.
Consider Gallelio's equations->
v=u+at--(equation-1) &
s=ut+1/2at^2--(equation-2)
where u-initial velocity & a-acceleration
My doubt is on following point;
If we...
So friction helps in movement,right?If my block would have been in free space compared to resting on a table with 0.4cof-->pulling force reuired is 0.4 times less than that in free space.
Hi,
If I take coificient of friction as 0.4 for wood table.
But I am not getting acceleration figure.I just want to move it from rest
and use a force by pushing it with hand.
Hi,
Consider a block sits on a table and its weight is 25N.So its weight is acting downwards
and I want to move this block horizontally and I am applying a force of 30N.
How I can calculate whether with this Force body moves?
Cheers
Abraham
