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...

Will you please help me with part C and part D?
A Review Constants Periodic Table Only about 10% of the electromagnetic energy from an incandescent lightbulb is visible light. The bulb radiates most of its energy in the infrared part of the electromagnetic spectrum. Part A If you place a 100-W lightbulb 2.1 m away from you, what is the intensity of the infrared radiation at your location? Assume that bulb radiates only visible light and infrared radiation. Express...
