âºâº Definition: Second. A second of arc or arcsecond is a unit of angular measurement which comprises one-sixtieth of an arcminute, or 1/3600 of a degree of arc or 1/1296000 (approximately 7.710-7) of a circle.
The resistance of a liquid to flowing is its viscosity.   Viscosity is a property arising from friction between  neighboring particles in a fluid that are moving at dif â¦ ferent  velocities. In liquids, it could be considered the thickness.
The flow of charge through wires is often compared to the flow of water through pipes. The resistance to the flow of charge in an electric circuit is analogous to the frictional effects between water and the pipe surfaces as well as the resistance offered by obstacles that are present in its path.
