    How Does the Weight of a Pendulum Affect Its Motion?

    As the Earth doesn't care how massive an object is when one leaves two bodies with different masses they fall with the same g=9.81 meter/second.second. so is with a pendulum as they release from their maximum height ,they won't become affected by their masses. But if you connect some mass...

    Magnetic Field of a long wire bent into a shape

    what you need is a sum of two fields: first field due to the straight wire and this field is perpendicular out of the page towards your eye which is your second term (mu,zero).I/2.pi.R. the field due to loop which is your first term that is (mu ,zero).I/2R. This second field is again...
