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

Acentrifuge in a medical laboratory rotates at an angular speed of 3,700 rev/min. when switched off, it rotates through 54.0 revolutions before coming to rest. find the constant angular acceleration (in rad/s2) of the centrifuge. your response is within 10% of the correct value. this may be due to roundoff error, or you could have a mistake in your calculation. carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. rad/s2
