Suppose wire X and wire Y are made of different materials, and have different lengths and cross-sectional areas. What is the ratio of the resistance of wire X to the resistance of wire Y? The length of wire X is one fifth the length of wire Y.
The radius of wire X is one third the radius of wire Y.
The resistivity of the material of wire X is half the resistivity of the material of wire

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?
