When an electric current flows through the filament of an incandescent light bulb, it gets very hot and glows (or incandesces). Consider a particular bulb with a filament with 180 Q resistance which carries a current of 1.00 A. Assume the length of the filament is L = 8.50 cm long with a radius of r0.800 mm

(a) Calculate the Poynting vector (in kW/m2) at the surface of the flament, associated with the static electric field producing the current and the current's static magnetic field magnitude direction kW/m2 Select-
(b) Fnd electric field magnetic field magnitudes of the static electric feld (in kV/m) and static magnetic field (in μ T) at the surface of the tiament. v/m

Consider a small frictionless puck perched at the top of a fixed sphere of radius r. if the puck is given a tiny nudge so that it begins to slide down, through what vertical height will it descend before it leaves the surface of the sphere? [hint: use conservation of energy to find the puck's speed as a func e conservation of energy to find the puck's speed as a function of its height at what value of this normal force does the puck leave the sphere? ] here on the puck.
