Hi good people, I have some problem with determining impact force acting on rubber-like elastic material (conveyor belt). The problem is: The object of mass M is released from the height H on conveyor belt which is clamped at the both ends and subjected to an uniaxial tensile force T. I...

I was thinking.when we mass produce electricity,we send out high amounts of negative magnetic fields.whats the possibility that when offsetting the planets natural balance of negative electromagnetism.the planets positive side would be over powered by the increase of negativity.do you think this...

( I'm not making a poll of this. It no opinion.) But a simple question, where would you be weighting the most? A - On the equator B - On the North pole because you are closest to the centre of the Earth C - On the North pole because there is no centrigufal force of the spinning Earth...
