How do you stop a fission chain reaction? In the operation of a nuclear reactor, fuel assemblies are put into place and then the control rods are slowly lifted until a chain reaction can just be sustained. As the reaction proceeds, the number of uranium-235 nuclei decreases and fission by-products which absorb neutrons build up. […]
What is balanced force give an example?
What is balanced force give an example? When two forces are the same strength but act in opposite direction, they are called balanced forces. Again, tug-of-war is a perfect example. If the people on each side of the rope are pulling with the same strength, but in the opposite direction, the forces are balanced. The […]

What frequency is gamma rays?
What frequency is gamma rays? Gamma rays have frequencies greater than about 10^19 cycles per second, or hertz (Hz), and wavelengths of less than 100 picometers (pm), or 4 x 10^9 inches. (A picometer is one-trillionth of a meter.) Is there a shorter wavelength than gamma rays? Electromagnetic energy travels as waves that vary in […]
Has anyone hit a homerun in every ballpark?
Has anyone hit a homerun in every ballpark? When this question was posed early in 2019, I had given the answer that Mark Reynolds and Curtis Granderson had homered in every MLB ballpark.

For larger objects (such […]
Why is the gravitational constant important?
Why is the gravitational constant important? The constant, G, determines the strength of Newton’s inverse square law in a particular system of physical units and is, not surprisingly, known as Newton’s constant of gravitation. It is considered to be a fundamental constant of nature. Gravity is also by far the weakest force. Who found the […]

What is SI unit of Hertz?
What is SI unit of Hertz? The symbol of the hertz in SI is Hz. The hertz is named for Heinrich Hertz (1857 – 1894), an early pioneer in electromagnetic research and the first person to demonstrate the transmission of electromagnetic waves through space. The hertz is a derived unit in the SI, equal to […]
