What is the purpose of WMAP?
What is the purpose of WMAP? The main goal of WMAP was to create extremely precise full-sky maps of the cosmic microwave background, improving upon the maps created by COBE. Since the differences in temperature are only on the order of 0.0002 degrees Celsius, precision was essential to obtaining useful information. What does Cobe stand […]
Why is the flowing water from the faucet repelled by charged balloon while the hair is attracted to it?
Why is the flowing water from the faucet repelled by charged balloon while the hair is attracted to it? When you bring the negatively charged balloon close to the stream of water, the hydrogen end is attracted towards the balloon and the oxygen end is repelled away from it. This pair of forces twists the […]
What is electroplating with example?
What is electroplating with example? Electroplating is the process of plating one metal onto another by hydrolysis, most commonly for decorative purposes or to prevent corrosion of a metal. There are also specific types of electroplating such as copper plating, silver plating, and chromium plating. The surface can be a metal or even plastic. What […]
What is an example of a prokaryote?
What is an example of a prokaryote? Examples of prokaryotes are bacteria, archaea, and cyanobacteria (blue-green algae). Is the term prokaryote useful?

What are 2 things that can affect strength of a muscle contraction?
What are 2 things that can affect strength of a muscle contraction? The peak force and power output of a muscle depends upon numerous factors to include: (1) muscle and fiber size and length: (2) architecture, such as the angle and physical properties of the fiber-tendon attachment, and the fiber to muscle length ratio: (3) […]
What do you notice about the size of the planets?
What do you notice about the size of the planets? The smaller, inner planets include Mercury, Venus, Earth, and Mars. The inner planets are rocky and have diameters of less than 13,000 kilometers.

What happens if white light is used in YDSE?
What happens if white light is used in YDSE? Therefore, if monochromatic light in Young’s interference experiment is replaced by white light, then the waves of each wavelength form their separate interference patterns The resultant effect of all these patterns is obtained on the screen. Therefore, the central fringe is white. What will happen when […]
Why was Austria Hungary so weak in ww1?
Why was Austria Hungary so weak in ww1? They didn’t have that bad of military failure. They were largely fighting a defensive war against Russia and later Italy. Austria Hungary had 1/3 of all Central Power losses. This is a massive over-simplification but in short it was due to the incompetence of Austro-Hungarian (AH) Military […]
When methane is completely combusted in oxygen?
When methane is completely combusted in oxygen? The atoms of one element are the same as atoms of another element. When methane is completely combusted in oxygen forming carbon dioxide and water, how does the mass of the reactant gases compare to the products? The masses of the reactants and products are equal. When methane […]
