OK well, this isn't a question as such, more a conceptual thing... The formula, B=(Weber)/(Area) gives the magnetic field strength, B in Tesla... . But when I rearrange in terms of magnetic flux, it's obviously (Tesla) X (Area). My question is, how is the flux (lines of force) defined by the...

thank you!

Hi everyone. I'm currently preparing for my upcoming mid year exam which examines: -motion in one and two dimensions -electronics and photonics -special relativity. I am in year 12, so I was hoping that you may be able to recommend some free exam papers/ any resources that could...

I agree. length can't be the same... I know the answer but will just give hints for now... Use pythag for lenghts.

think or know?

To be honest I don't think it's possible, seeing as though it's asking for the tension... This would require a quantity for mass which is not given. If anything the answer would be in terms of K2.

I'm sorry but what exactly does it mean with 'repect to a physically well defined frame?"

It has REALLY been bugging me lately. I'm studying Einstein's Special Rel and am finding it annoying to determine who observes the proper length and time in the following conditions: An electron accelerator is 4km long and can accelerate electrons up to speeds of .9999995c. So when asked...

Great. Thanks for this

Hi all.. I am getting a little confused between the principles of 1.Conservation of Kinetic Energy; and 2.Conservation of Momentum... What is the difference between the two (if any) and can we use the idea of elastic collisions in both examples? Cheers, ja_tech
