An electron, moving in a uniform magnetic field, moves in a circle path perpendicular to the field lines and takes time 2t for each circle. if the electron's speed is tripled, what would now be its new period in terms of t?

Iwas going to ask that quesytion  sorry dude i dont  know : (    : /

Honestly "global warming" may be a slight possiblity, however they called it "climate change" because its not real, in fact we had one of our coldest days here not too long ago, and the "issues" with this subject is a blindfold for actual problems.

When you go to ask a qustion there will be a picture of a paper clip looking thing and then it will pop up your files and you click on the imajes and then you up load it

It really doesn't matter for any of the questions that you've listed.
