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

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day

that would be because of both gravity and friction. so     c
