Which Quantity Is Constant? A constant-quantity is a constant value of some physical-quantity, like 3 meters or 55 miles per hour. Constant quantities are distinguished from function-quantities, which map some quantities to other quantities. Which physical quantity is constant? But the speed is a scalar quantity and it is independent of direction therefore, the speed
Is Density A Dimensionless Quantity? Relative density is a dimensionless quantity and it’s measurable, on which scale is hydrometer calibrated? If relative density is a dimensionless quantity and it’s measurable. Also it’s widely used in industry to determine the concentration of a substance in a solution. Which is the dimensionless quantity? In dimensional analysis, a
Is Force Dimensionless Quantity? The ratio of the internal forces to the external forces will depend upon its speed, and the viscosity of the fluid, and the size of the body. But the ratio of the internal to the viscous forces is dimensionless, so it must depend on some combination of the viscosity, speed V
What Are The Dimensions Of The Quantity? The dimension of a physical quantity can be expressed as a product of the basic physical dimensions such as length, mass and time, each raised to a rational power. The dimension of a physical quantity is more fundamental than some scale unit used to express the amount of
