An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

Wavelength, frequency, and energy are related. what happens to a wave as it’s wavelength gets shorter?

True or false graphs must include scales that increase by the same amount
