Solution)
Given,
Emissivity, E=0.35
Radius, r=0.19 m
Temerature t=273+24=297 K
We know, Power, P= sigma*E*A*T^4
Substitute values,
P=(5.67*10^-8)*(0.35)*(4pi*0.19^2)*(297)^4= 70.01 J/s (Ans)

Review Con: Part A An incandescent light bulb uses a coiled filament of tungsten that is 580 mm long with a diameter of 46.0 um. At 20.0°C tungsten has a resistivity of 5.25 x 1012.m. Its temperature coefficient of resistivity is 0.0045 (Cº) , and this remains accurate even at high temperatures. The temperature of the filament increases linearly with current, from 20°C when no current flows to 2520°C at 1.00 A of current What is the resistance of the...
