What is Ey(R), the value of the y-component of the electric field at point R, located a distance 1.35 cm from the infinite sheet of charge?

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

Crowbar of 5 metre is used to lift an object of 800 metre if the effort arm is 200cm calculate the force applied

For which pair of objects would adding the same a
