Three resistors are made out of three different materials and have different (but uniform) cross-sections.
Resistor 1 has a circular cross-section of radius 1.61 mm.
Resistor 2 has a square cross-section with a side length of 4.77 mm.
Resistor 3 cross-section is a right triangle with two sides of length 6.47 mm.
All of the resistors are 0.613 cm in length.
Use the provided table of resistivities to calculate the resistance of each resistor.
Material 1 7.03 x 10⁻³ Ω.m
Material 2 0.585 Ω.m
Material 3 4.63 x 10⁻⁵ Ω.m

The law of entropy can also be called the law of increasing disorder, but this law seems to contradict the existence of living organisms that are able to organize chemicals into organic molecules. prepare for a class debate on the validity of the following arguments: a. living things are not subject to the laws of thermodynamics. b. the increase in the universe's entropy due to life processes is greater than the decrease in entropy within a living organism.
