Write a program that allows the user to convert a temperature given in degrees from either celsius to fahrenheit or fahrenheit to celsius. use the following formulas: degrees_c = 5(degrees_f− 32)/9 and degrees_f = (9(degrees_c)/5) + 32) prompt the user to enter a temperature and either a c or c for celsius or an f or f for fahrenheit. convert the temperature to fahrenheit if celsius is entered, or to celsius if fahrenheit is entered. display the result in a readable format. if anything other than c, c, f, or f is entered, print an error message and stop.

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody

To save energy, the air supply to a 2000 ft office has been shut off overnight and the room temperature has dropped to 40°f. in the morning, the thermostat is reset to 70°f and warm air at 120 f begins to flov in at 200ft'/min. the air is well mixed within the room, and an equal mass flow of air at room temperature (changing with time) is withdrawn through a return duct. the air pressure is nearly 1 atm everywhere. ignoring heat transfer with the surroundings and kinetic and potential energy effects, estimate how long it takes for the room temperature to reach 70°f. plot the room temperature as a function of time.
