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.
Resistance, measured in Ohms, tells us how hard it is for a current to flow through a circuit component. The size of the current flowing depends on the potential difference (voltage [voltage: The potential difference of a cell, electrical supply or electric component.It is measured in volts, 'V'.esistance, measured in Ohms, tells us how hard it is for a current to flow through a circuit component.
