Why does Proton move in electric field? The electric field is directed from a high electric potential to a low electric potential. The electric force acts on the positive charge in the direction of the electric field, therefore, the proton (positive charge) moves from high electric potential to low electric potential. Where does the electric […]

Why nitrogen-fixing bacteria are important? Nitrogen-fixing bacteria, microorganisms capable of transforming atmospheric nitrogen into fixed nitrogen (inorganic compounds usable by plants). More than 90 percent of all nitrogen fixation is effected by these organisms, which thus play an important role in the nitrogen cycle. Why can’t plants fix nitrogen?

What are the strongest and weakest bonds? This means Ionic bonds tend to dissociate in water. Thus, we will think of these bonds in the following order (strongest to weakest): Covalent, Ionic, Hydrogen, and van der Waals. Also note that in Chemistry, the weakest bonds are more commonly referred to as “dispersion forces.” What is […]

What is the relation between power and voltage? Electrical Energy in Circuits In other words, Energy = power x time and Power = voltage x current. Therefore electrical power is related to energy and the unit given for electrical energy is the watt-seconds or joules. Electrical power can also be defined as the rate of […]

What is ∈ called? The symbol ∈ indicates set membership and means “is an element of” so that the statement x∈A means that x is an element of the set A. In other words, x is one of the objects in the collection of (possibly many) objects in the set A. Which are the real […]

How long can I dive at 60 feet? The old guideline for safe ascent was 60 feet per minute, which has been revised down to to the current recommendation of 30fpm. The rate of ascent is more critical at shallower depths, so many might ascend faster at deeper depths and slow to 30fpm or less […]

What is the meaning of Coastal? Coastal things are near the ocean. If you like spending time at the beach, you might take a trip to a sunny, coastal vacation spot. The coast is the land that borders an ocean or sea, and the adjective coastal describes things that affect the coast or are located […]
