[b]1. A uniform sperical shell of mass Ms and radius R rotates about a vertical axis on frictionless bearings. A light cord passes around the equator of the shell over a pulley (a disk of mass Mp and radius r) and is attached to a small block of mass m that is otherwise free to fall under the...

So for my physics independent study project. I am studying the resistance vs. temperature in non-ohmic material. I passed different currents through the light bulb and took the surface temperature with a thermocouple. How can I find the temperature of filament using the surface temperature...
