Why does GM counter need quenching? Quenching. When a GEIGER-MULLER tube operates in Geiger region, the secondary electrons increase the current pulse by further ionization of gas molecules. Therefore, it is desirable to prohibit the production of spurious pulse following the main required plus due to a single particle entry. Can GM counter detect neutrons? […]

How do you know if a molecule is radical? My TA told us that the easiest way to tell if a molecule is a radical is if it has an odd-numbered amount of valence electrons. If it has an even number of valence electrons then it would not be a radical. How are radicals applied […]

How does natural selection affect humans? Probably more than you might think, a new study suggests. Natural selection is still influencing the evolution of a wide variety of human traits, from when people start having children to their body mass index, reports a study published Monday in the journal Proceedings of the National Academy of […]

What is high price elasticity? When the value of elasticity is greater than 1.0, it suggests that the demand for the good or service is affected by the price. A value that is less than 1.0 suggests that the demand is insensitive to price, or inelastic. Are luxury goods elastic? Compared to essential goods, luxury […]

What are the four laws of logic? The Law of Identity; 2. The Law of Contradiction; 3. The Law of Exclusion or of Excluded Middle; and, 4. The Law of Reason and Consequent, or of Sufficient Reason.” What is the use of logic in law? One use of logic in the law is motivated by […]

How does center of mass affect acceleration? By using the the center of mass as the height, moving it will affect the amount of time that the car is accelerated by gravity, which is comparable to the amount of potential energy the car had. In which situation Centre of mass has no acceleration? If the […]

What is the most important objective of lighting? Illuminating action on stage One of the most important functions of lighting design is illuminating the action on stage. Lighting is needed so that the audience can see clearly what is happening. Which light is used in 3 point lighting to get rid of shadows behind the […]

Which quantity has same unit? Answer: Momentum and impulse both has same unit Kg ms-1. What are the 3 units of work? The SI unit of work is joule (J). Joule is defined as the work done by a force of one newton causing a displacement of one meter. Sometimes, newton-metre (N-m) is also used […]

What happens when the earth moon and sun are not aligned? Partial Solar Eclipse- This happens when the sun, moon and Earth are not exactly lined up. The sun appears to have a dark shadow on only a small part of its surface. Annular Solar Eclipse- An annular eclipse happens when the moon is farthest […]
