What is the importance of isotopes in our daily life? Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes. What means 2he? […]
Is deceleration a physics word?
Is deceleration a physics word? Rick suggests: “Deceleration” is not actually a term in physics. It is only an English word used in common speech, meaning “a decrease in speed.” The problem with this word is that some students mistake it to mean the same as negative acceleration. Is deceleration a vector quantity? In a […]
What does a horizontal line indicate?
What does a horizontal line indicate? A horizontal line is commonly used in technical analysis to mark areas of support or resistance. A horizontal line runs parallel to the x-axis. In technical analysis, the horizontal line is typically drawn along a swing high, or a series of them, where each high in the series stopped […]
Is chromatin made of nucleosomes?
Is chromatin made of nucleosomes? Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. Under the microscope in its extended form, chromatin looks like beads on a string. The beads are called nucleosomes. Each nucleosome is composed of DNA wrapped around eight proteins called histones. What are […]
Why is a car crash inelastic?
Why is a car crash inelastic? Collisions are considered inelastic when kinetic energy is not conserved, but this could be from either a loss or gain or kinetic energy. For example, in an explosion-type collision, the kinetic energy increases. It is common for people to try to conserve energy in a collision. What happens in […]
What is the coating on the inside of a light bulb?
What is the coating on the inside of a light bulb? The white powder coating inside the glass tubing of a CFL contains a fluorescent coating. When electricity enters a CFL, mercury and argon fumes inside the bulb produce invisible ultraviolet (UV) light. This UV light reacts with the fluorescent coating to produce the white, […]

Which gases is not a greenhouse gas?
Which gases is not a greenhouse gas? Examples for greenhouse gases: Carbon dioxides, Methane, Chlorofluorocarbon, sulphur dioxide. Whereas oxygen, nitrogen and argon are not examples of greenhouse gases. Is nitrogen monoxide a greenhouse gas? The direct greenhouse gases are carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4). The indirect greenhouse gases are non-methane volatile […]
What two things started Earth?
What two things started Earth? When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust. Why […]
