In this swimming pool design, explain how to find the area of the pool’s surface.

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?

What determines the amount of inertia an object has

When the magnetic domains in a material can be aligned, but eventually drift out of alignment, the material is
