Planck radiation law
A law that defined blackbody radiation better than its predecessor, therefore resolving the ultraviolet catastrophe. It is depend on the supposition that electromagnetic radiation is quantized.
At thermodynamic temperature T, for a blackbody, the radiancy R onto a range of frequencies among nu & nu + dnu is provided by
R = 2 pi h nu3/[c3 [exp (h nu/k T) - 1]].
Assigned homework a. The objective of this problem is to get a sense of the tradeoff between cross-section and stiffness for beam structural member. Consider a beam that is 1 me

A 30-g car rolls from a hill 12 cm high and is traveling at 154 cm/s as it travels along a 275 cm horizontal track. What is the momentum of the car?
Resistance in Series: In such a combination the resistors give a single path to the passage of current and similar current passes by each of the resistors.
