What is difference between fabrication and falsification? (1) Fabrication is making up data or results and recording or reporting them. (2) Falsification is manipulating research materials, equipment, or processes, or changing or omitting data or results such that the research is not accurately represented in the research record. What is the principle of falsification? The […]

How do you find the frequency in Hz? Frequency is how many complete waves go by per second. We denote frequency by Frequency is measured in Hertz = Hz = 1/seconds. For example, radio station KUGN broadcasts at a frequency of 590 KHz. What is the wavelength of the radio waves? How do you find […]

Will humans ever travel to other galaxies? The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible. How old is our galaxy? 13.51 billion years How long before our […]

Can DNA tell if you are half-siblings? DNA is unique to each individual unless he or she is an identical twin. However, DNA testing can help you identify siblings and half-siblings because you share more DNA with those people than with people not related to you. But simply sharing DNA with someone doesn’t necessarily mean […]

What is the use of Maxwell equation in thermodynamics? Maxwell relations are thermodynamic equations which establish the relations between various thermodynamic quantities (e.g., pressure, P, volume, V, Entropy, S, and temperature, T) in equilibrium thermodynamics via other fundamental quantities known as thermodynamical potentials—the most important being internal energy. What is B in Maxwell equation? The […]

Is Black an absence of color? Is black the absence of color? In science, black is the absence of light. And color is a phenomenon of light. But a black object or black images printed on white paper are made from pigment, not light. Is black or white absence of color? In physics, a color […]

What is the main function of Golgi complex? A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell. Named after its discoverer, Camillo Golgi, the Golgi body appears as a series of stacked membranes. […]

How does a fan create suction? Suction is created by the effects of centrifugal force acting upon the spinning air within the fan. As the fan rotates, the spinning air moves outward away from the hub, creating a partial vacuum which causes more air to flow into the fan. How can I increase the airflow […]

How do you know if it is waxing or waning? Look for the moon at sunset. If you can see it, it’s waxing. After full moon, when it’s in its waning phase, it isn’t visible at sunset. If you live in the Southern Hemisphere, the shape is reversed; the shadow part of the waxing moon […]

Can a planet break? Is it possible for a planet to break apart? Yeah. There are small planetary bodies in the solar system that are tight clouds of rocks, ice and other solid matter in a that orbit close enough that they have a gravity well. What is unique about Janus and Epimetheus? Epimetheus and […]
