2) The current through a wire is perpendicular to a 0.76-T magnetic field. If the current in the wire is 3.3-A and the length of the wire is 0.77-m
long, what is the magnitude of the force on the wire?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.
