Which of the following is not an example of non economic activity?

Non economic activities are those those don't give more money but done for satisfaction

examples ;:Housewives doing day to day to work like cooking, laundry and so on

.A person doing a work for hobby like gardening, fishing, painting and so on

.Work done for charity like taking tuition classes of poor children, providing free services to earthquake victims, helping a blind man in crossing road and so on

.Work done for personal satisfaction like sleeping in afternoon in free time instead of working and earning money or playing video games on Sundays and so on.

Similar Class 11 Doubts

Attempt All sub parts from each question.Newtonian and non-Newtonian fluid: Viscosity is the physical property that characterizes the flow resistance of simple fluids. Newton’s law of viscosity defines the relationship between the shear stress and shear rate of a fluid subjected to a mechanical stress. The ratio of shear stress to shear rate is a constant, for a given temperature and pressure, and is defined as the viscosity or coefficient of viscosity. Newtonian fluids obey Newton’s law of viscosity. The viscosity is independent of the shear rate. Example: air, water, alcohol etc. Non-Newtonian fluids do not follow Newton’s law thus, their viscosity (ratio of shear stress to shear rat e) is not constant and is dependent on the shear rate. Example: honey, ketchup etc. Non-Newtonian fluids can be categorized into four types based on the way a fluid’s viscosity changes in response to variations in shear rate.• Pseudoplastic: Materials whose viscosity decreases as the shear rate increases. This type of flow behavior is sometimes called shear thinning. Example: Cake batter, agar-agar and fruit juice concentrates, nail polish etc.• Dilatant: M aterials whose viscosity increases as the shear rate increases. This type of behavior is sometimes called shear-thickening. Example: Suspension of corn starch in water and candy compounds etc..• Thixotropic: M aterials whose viscosity decreases when sheared at a constant rate over time. Example: Yogurt, gelatin gel, honey etc.• Rheopectic: M aterials whose viscosity increases when sheared at a constant rate over time. Example: Printer ink, gypsum paste etc.Q. A fluid, whose viscosity changes with the rate of deformation or shear stain is known as
