What is the importance of projectile motion? The projectile motion emphasizes one important aspect of constant acceleration that even constant acceleration, which is essentially unidirectional, is capable to produce two dimensional motion. The basic reason is that force and initial velocity of the object are not along the same direction. Is Pythagorean theorem only for […]
Can carbon dating be faked?
Can carbon dating be faked? Employed since the 1940s, radiocarbon dating — also referred to as carbon-14 dating — makes it possible to identify forgeries. However, radiocarbon dating has one major drawback: the sample may be falsified by the use of old materials, which is difficult to detect using this method. Why can’t we use […]
What are antacids give an example?
What are antacids give an example? Examples of antacids include: Aluminum hydroxide gel (Alternagel, Amphojel) Calcium carbonate (Alka-Seltzer, Tums) Magnesium hydroxide (Milk of Magnesia) Gaviscon, Gelusil, Maalox, Mylanta, Rolaids. Pepto-Bismol. How pH is maintained in buffer solution? A buffer is a special solution that stops massive changes in pH levels. Every buffer that is made […]
How does a fuse prevent short circuit?
How does a fuse prevent short circuit? A fuse or circuit breaker prevents this by ”blowing,” or breaking the circuit, when an overload occurs. Fuses screw into threaded sockets inside the fuse box. The fuses contain a thin strip of metal that melts if the current (or amperage) flowing through that circuit exceeds the amount […]
Why does the S block span 2 groups?
What is meant by enthalpy of reaction?
What is meant by enthalpy of reaction? The Heat of Reaction (also known and Enthalpy of Reaction) is the change in the enthalpy of a chemical reaction that occurs at a constant pressure. It is a thermodynamic unit of measurement useful for calculating the amount of energy per mole either released or produced in a […]
Where is potassium most commonly found?
Where is potassium most commonly found? Potassium is found extensively as potash (KOH). It is mined in Germany, USA, and elsewhere. Minerals such as sylvite (KCl), carnallite, and langbeinite, are found in ancient lake and sea beds….Abundances of potassium in various environments. Location ppb by weight ppb by atoms Stream 2300 59 Human 2000000 320000 […]
What is displacement reaction in simple words?
What is displacement reaction in simple words? Displacement reactions occur when a metal from the electrochemical series is mixed with the ions of a metal lower down in the electrochemical series. The atoms of the more reactive metal push their electrons on to ions of the less reactive metal. What is displacement reaction of Class […]
What do postganglionic neurons release?
What do postganglionic neurons release? Postganglionic fibers in the sympathetic division are adrenergic and use norepinephrine (also called noradrenalin) as a neurotransmitter. In the sympathetic nervous system, the postganglionic neurons of sweat glands release acetylcholine for the activation of muscarinic receptors. Which is longer Preganglionic or Postganglionic? In general, parasympathetic preganglionic neurons are longer than […]
Which part of UK has best weather?
Which part of UK has best weather? South West part Why is England so warm for its latitude? Temperature. The British Isles undergo very small temperature variations. This is due to its proximity to the Atlantic, which acts as a temperature buffer, warming the Isles in winter and cooling them in summer. Coastal areas tend […]
