What is the SI unit of Centre of curvature? Then the units for curvature and torsion are both m−1. Explanation #1 (quick-and-dirty, and at least makes sense for curvature): As you probably know, the curvature of a circle of radius r is 1/r. What is Centre of curvature in light? The point in the center […]
How are the SI units defined?
How are the SI units defined? The SI base units are the standard units of measurement defined by the International System of Units (SI) for the seven base quantities of what is now known as the International System of Quantities: they are notably a basic set from which all other SI units can be derived. […]
Is it OK to not understand something?
Is it OK to not understand something? Not understanding something can affect our confidence. It makes us feel insecure because we don’t understand what’s going on, or which steps we need to take. That is normal, but it’s good if you can try and come up with a plan before those thoughts get the chance […]

What transports osmosis?
What transports osmosis? Osmosis is the diffusion of water through a semipermeable membrane according to the concentration gradient of water across the membrane. Whereas diffusion transports material across membranes and within cells, osmosis transports only water across a membrane and the membrane limits the diffusion of solutes in the water. Is Osmosis a active process? […]

Types of natural selection: Different types of natural selection can impact the distribution of phenotypes within a population.In (a) stabilizing selection, an average phenotype is favored.In (b) directional selection, a change in the environment shifts the spectrum of phenotypes observed.In (c) diversifying selection. Is natural selection true? Natural […]
What are the 3 assumptions of science?
What are the 3 assumptions of science? Understanding science: scientific assumptions Nature is orderly, and the laws of nature describe that order. We can know nature. All phenomena have natural causes. Nothing is self evident. Knowledge is derived from acquisition of experience. Knowledge is superior to ignorance. Do scientists make assumptions? All scientific tests involve […]
Does the mass of the satellite have any impact on its orbit?
Does the mass of the satellite have any impact on its orbit? The mass of the satellite definitely affects where it stays in the orbit (leo, meo or geo). Gravitational force between two objects is directly proportional to the product of their masses and indirectly proportional to the square of the distance between them. Does […]
