Thicker cable loses less thermal energy.
Losses for underground armored cable can include resistance losses due to the resistance of the conductors, dielectric losses due to the insulating material, and skin effect losses at high frequencies. Additionally, there can be losses due to environmental factors like moisture or temperature variations impacting the cable's performance.
It is done to carry more current at rated power & to reduce the power loss as compared to cable since a bus-bar has more area compared to cable so resistance is less & hence losses are reduced.

copper cost more to mine then aluminum so aluminum will cost less then copper cable.
The length of the cable is determined by the distance from the center of the distribution panel to the center of the load.
A straight cable will be sharper, have less play in the system.
The keyboard cable is orange with less prongs and the mouse cable is green with more prongs.
less cable

There are losses in d.c. transmission lines, due to their resistance. But there are no reactive losses. So, d.c. transmission lines have less losses in comparison to an equivalent a.c. transmission line.
It is not true. Attenuation is higher in twisted pair cable. See related links: It is, because coaxial cable is concluded system and magnetic field of signal in coaxial cable is kept inside the cable so there is little energy losses because no energy is spent on inducing currents outside of cable.
