How does shape affect diffusion? Diffusion is like going through a net or sieve. Smaller sizes and shapes pass through more easily than large ones. What is the relationship between cell size and diffusion? The surface-to-volume ratio of a sphere is 3/r; as the cell gets bigger, its surface-to-volume ratio decreases, making diffusion less efficient. […]
What are the reasons of non-sampling errors?
What are the reasons of non-sampling errors? Some of the major reasons that lead to the non-sampling errors are: Inadequate data specification or data being inconsistent with the objective of survey or census. Inadequate methods of data collection. Duplication of a subject in the survey. Lack of trained investigators. Lack of supervision of primary staff. […]

Is gold a ferromagnetic metal?
Is gold a ferromagnetic metal? Gold (Au) in its bulk form, like the metal in a wedding ring, is not considered a magnetic material. Technically, it is classified as “diamagnetic”, meaning that it can be repelled by a magnetic field, but cannot form a permanent magnet. Why Fe is ferromagnetic? The popular understanding of a […]

Respiration. Burial. Extraction. Combustion. Exchange. Is the carbon cycle important for humans and plants? The carbon cycle is […]
Which of the following will not affect the rate of evaporation?
Which of the following will not affect the rate of evaporation? Explanation: The rate of evaporation is depends on some factors like temperature, wind speed, surface area etc. But not on the mixed absolute heavy impurities. At what temperature does water start evaporating? 212° F How do you calculate the evaporation rate of water? I […]
What is unit of modulus of elasticity?
What is unit of modulus of elasticity? The units of modulus of elasticity are pressure units, as it is defined as stress (pressure units) divided by strain (dimensionless). Most commonly the units are Pascals (Pa) which is the SI unit, or pounds per square inch (psi) depending on the industry or geographical location. Is tensile […]
Where is productive efficiency?
Where is productive efficiency? In long-run equilibrium for perfectly competitive markets, productive efficiency occurs at the base of the average total cost curve — i.e. where marginal cost equals average total cost — for each good. What is meant by productive efficiency? Production efficiency is an economic term describing a level in which an economy […]
