In solid light sources such as the tungsten filament in an incandescent bulb, the electrons can have any value of energy due to thermal vibration and collisions between atoms. Based on this, what do you think the spectrum for the incandescent bulb will look like

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4×10 to the power of 23 kg, radius = 3.4×10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3×10 to the power of 8 km from the sun.)
