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.
Best Answer: Viscosity is the physical property used to determine a liquid's resistance to flow. Whether or not a liquid will flow quickly determines its viscosity. Think of spilling a glass of water on a flat surface. It disperses across the surface until there is no more water to disperse.
