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 […]
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 […]
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 […]
Is Shiva linga a male organ?
Is Shiva linga a male organ? According to Sivaya Subramuniyaswami, the lingam signifies three perfections of Shiva. According to Rohit Dasgupta, the lingam symbolizes Shiva in Hinduism, and it is also a phallic symbol. Since the 19th-century, states Dasgupta, the popular literature has represented the lingam as the male sex organ. Is Shiva male or […]

Why capacitors are of little use for storage of energy?
Why capacitors are of little use for storage of energy? Capacitors are not ideal for energy storage because they discharge very fast and then they are of no use until recharged. Explanation: They are designed to perform different tasks than a battery. They are not suitable to deliver slow discharge for a long time like […]
Does all the ice melt calorimetry?
Does all the ice melt calorimetry? Once all the ice has melted, the temperature of the liquid water rises, absorbing heat at a new constant rate. At 100oC the water begins to boil….Heat and Change in Physical State. Substance Mercury Melting Point (oC) –38.9 ΔHfus, (J/g) 11.8 Boiling Point (oC) 357 ΔHvap (J/g) 272 When […]
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, […]
What does it mean when a nucleus is stable?
What does it mean when a nucleus is stable? Definition. Nuclear stability means that the nucleus of an element is stable and thus it does not decay spontaneously emitting any kind of radioactivity. Those nuclei with the highest binding energy per nucleon are the most stable with respect to destructive nuclear reactions. What is the […]
Can an explosion trigger an earthquake?
Can an explosion trigger an earthquake? A nuclear explosion can cause an earthquake and even an aftershock sequence. However, earthquakes induced by explosions have been much smaller than the explosion, and the aftershock sequence produces fewer and smaller aftershocks than a similar size earthquake. Not all explosions have caused earthquakes. Can a nuke cause a […]
