RGB consists of24 bits how many bits are assigned to each color element?

In RGB color model, each color element (Red, Green, Blue) is assigned 8 bits, for a total of 24 bits. This allows for 256 possible shades of each color (2^8 = 256).


How is mendelevium obtained?

Mendelevium is usually produced in laboratories by bombarding heavy isotopes of einsteinium with alpha particles or neutrons. This process creates small amounts of mendelevium which can then be isolated and studied. Mendelevium is a highly radioactive element and only small quantities have ever been produced.


What is sodium palmate?

...First off, the spelling is wrong. It's "palmitic" acid, not "palmatic" acid. The formula is C15H31CO2CH3. I hope that helps. =]] ---- resources: http://www.biodiesel.org/pdf_files/fuelfactsheets/Weight&Formula.PDF


What is the ratio of parent to daughter isotopes after eight half lives?

100(.50)^.5 = 70.71%..50 represents the 50% remainder per half-life, taken to the power of .5 or the number of half-lives that pass, all multiplied by 100 to make the answer a percentage.


How could you seperate a mixture of sand and small pebbles?

In geology and civil engineering sand and gravel have specific meanings! Sand is material that varies in diameter from 1⁄16 mm upto 2 mm. Any material larger than this is either gravel (>2 to 4 mm), a pebble (>4 to 64 mm), a cobble (>64 to 256), or a boulder (>256 mm). As the difference between gravel and sand is the size of the grains then a sieve with a mesh equal to the maximum diameter of sand could be used to sieve the material. All the material passing through the sieve would be sand (or smaller material) and anything trapped on the sieve would be gravel or larger material.
