Las placas descritas en el problema 25.27 se encuentran en el vacío se suelta en la placa negativa y cae libremente en la placa positiva

Acoil suspended freely, points in some direction when no current is passed through it . can you tell what will happen when a current is passed though it?

Why does gravity have a lesser than grater effect on higher altitudes?

The average atmospheric pressure on earth is approximated as a function of altitude by the relation patm = 101.325 (1 − 0.02256z)5.256, where patm is the atmospheric pressure in kpa, and z is the altitude in km with z = 0 at sea level. determine the approximate atmospheric pressures at atlanta (z = 306 m), denver (z = 1610 m), mexico city (z = 2309 m), and the top of mount everest (z = 8848 m).
