Can nitrous oxide kill you? Nitrous oxide can be habit-forming, mainly because of its short-lived effect (generally from 1–5 minutes in recreational doses) and ease of access. Death can result if it is inhaled in such a way that not enough oxygen is breathed in. Is NOS the same as laughing gas? “Laughing Gas” is […]
What happens when two objects of equal mass collide?
What happens when two objects of equal mass collide? Two objects that have equal masses head toward each other at equal speeds and then stick together. The two objects come to rest after sticking together, conserving momentum but not kinetic energy after they collide. Some of the energy of motion gets converted to thermal energy, […]
What causes rear drum brakes to grab?
What causes rear drum brakes to grab? One of the most common causes of one or two wheel lockup on drum brake equipped vehicles is the service and/or parking brake adjustment. If the parking brake system is not de-adjusted properly before the brake shoes are adjusted it will cause the rear brakes to engage too […]
What is Spin formula?
What is Spin formula? Electron Spin or Spin Quantum Number is the fourth quantum number for electrons in atoms and molecules. Denoted as ms, the electron spin is constituted by either upward (ms=+1/2) or downward (ms=−1/2) arrows. What is meant by LS coupling? In atomic spectroscopy, Russell–Saunders coupling, also known as LS coupling, specifies a […]
What if 2 sperm enter an egg?
What if 2 sperm enter an egg? Each sperm cell contains half the father’s DNA. The researchers say it appears that after fertilization, the DNA from the egg and two sperm divided, then got divvied up to create three embryos. Two of the these had enough egg DNA and sperm DNA to make viable embryos. […]
How do maglev trains start and stop?
How do maglev trains start and stop? what is the braking system in maglev? In a maglev system, the train is not only held up by magnets (often using some superconducting electromagnets) but also pulled forward by these magnets. Air friction will gradually slow the train down if the changing electromagnets aren’t timed to pull […]
What color does the human eye see best?
What does an HR diagram show?
What does an HR diagram show? The Hertzsprung-Russell Diagram is a graphical tool that astronomers use to classify stars according to their luminosity, spectral type, color, temperature and evolutionary stage. Stars in the stable phase of hydrogen burning lie along the Main Sequence according to their mass. How was the HR diagram created? It originated […]
Is ADHD a sign of mental retardation?
Is ADHD a sign of mental retardation? Hyperactivity syndromes and disorders (ADHD and HKD) include the symptoms of overactivity, inattention, and impulsivity, which occur in many other mental disorders as well, including mental retardation (MR). It is not surprising that symptoms of ADHD occur significantly higher in children with learning disabilities. Are people with ADHD […]
What is the most important chemical regulator of respiration?
What is the most important chemical regulator of respiration? CO2 What are the major transport mechanism for carbon dioxide? Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate. The majority of carbon dioxide is transported as […]
