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.
Science. Viscosity is a measurement of how resistant a fluid is to attempts to move through it. A fluid with a low viscosity is said to be thin, while a high viscosity fluid is said to be thick.. It is easier to move through a low viscosity fluid (like water) than a high viscosity fluid (like honey). Newtonian and Non-Newtonian Fluid Viscosity Most common fluids, called Newtonian fluids (yes, another thing named after that Newton), have a constant viscosity. 1  There is a greater resistance as you increase the force, but it's a constant proportional increase. In short, a Newtonian fluid keeps acting like a fluid, no matter how much force is put into it.
