Maglev trains, like the one shown in the picture, to 600 miles per hour. Magnets on the
use magnet fields to travel up
bottom of the train and on the tops of the rails have
similar magnetic poles. Based on
properties of magnets, how do
ose magnets affect the train?

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j

How to tell if a molecule is polar or nonpolar with electronegativity
