Two long, parallel wires are separated by 2.41 cm and carry currents of 2.89 A and 3.05 A , respectively. Find the magnitude of the magnetic force that acts on a 4.67 m length of either wire.

Porque crees que el agua no podia subir mas de 10 m de altura con ese tipo de bomba

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?

Which statement correctly describes the interaction between magnetic poles? north and south poles attract each other. north and south poles repel each other. two north poles will attract each other. two south poles will attract each other.
