Q1: In Newton's viscosity equation , the coefficient (μ) is known as coefficient of

ANS:E - all the above.

Viscosity is a fundamental property of fluids that describes their resistance to flow. It is a measure of the internal friction within a fluid as it moves. The higher the viscosity, the more resistant the fluid is to flow. Viscosity is an essential parameter in fluid dynamics and has significant implications in various fields, including engineering, physics, and biology. There are several terms related to viscosity:

1. Viscosity: Viscosity, often denoted by the symbol �μ (mu), is a measure of a fluid's resistance to deformation under shear stress. It is essentially a measure of the internal friction between adjacent layers of fluid as they move relative to each other. Viscosity can be influenced by factors such as temperature, pressure, and the composition of the fluid.
2. Absolute Viscosity: Absolute viscosity refers to the resistance of a fluid to shear stress and is typically denoted by the symbol �μ. It represents the ratio of shear stress to the velocity gradient in a fluid. Absolute viscosity is usually measured in units of Pascal-seconds (Pa·s) in the International System of Units (SI).
3. Dynamic Viscosity: Dynamic viscosity is another term for absolute viscosity. It reflects the fluid's internal resistance to flow and is determined by the fluid's molecular structure and the forces acting between its molecules. Dynamic viscosity is commonly used in fluid dynamics to quantify the frictional forces experienced by a fluid as it flows.
4. Simple Viscosity: There is no specific term as "simple viscosity" in the context of fluid dynamics or viscosity measurements. It's possible that "simple viscosity" could refer to the basic concept of viscosity itself, without delving into specific types or measurements. However, in technical discussions, terms like absolute viscosity or dynamic viscosity are more commonly used to describe viscosity properties.
