Sudden Infant Death Syndrome (SIDS), according to a definition on the Mayo Clinic website, is the unexplained death, usually during sleep, of a seemingly healthy baby less than a year old.. The cause is still unknown, but it does not appear to be suffocation, according to the SIDS Network.
Albedo (/Ã¦lËbiËdoÊ/) is a measure for reflectance or optical brightness (Latin albedo, whiteness). It is dimensionless and measured on a scale from zero (corresponding to a black body that absorbs all incident radiation) to one (corresponding to a white body that reflects all incident radiation).
4 units are reflected by the surface. Therefore a total of 49 units are removed from the 100 units. The Earth receives the remaining 51 units. Of the 49 units, 30 are reflected back into space. The albedo is a measure of the reflectivity of the surface - 30 units in the example given above.
