What happens if an atom is not electrically neutral? Atoms which are not electrically neutral are called ions. One can collect electric charge by transferring electrons. Materials with an excess of electrons are negatively charged. Those with a deficiency of electrons are positively charged. What if there is no electron? You would become plasma as […]

A) The next lower octane aviation gas. B) Unleaded automotive gas of the same octane rating….2.3.2.4.5.A.1. 2.3.2.4.5.A.1 PAR PRG PRH RPA RPG […]

What is beta decay process? Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other. In beta minus decay, a neutron decays into a proton, an electron, and an antineutrino: n Æ p + e – +. What is […]

How do you calculate watts? AC three phase amps to watts calculation formula P(W) = √3 × PF × I(A) × VL-L(V) So watts are equal to square root of 3 times power factor PF times amps times volts: watt = √3 × PF × amp × volt. or. W = √3 × PF × […]

How long is the fall equinox? 12 hours What happens on the autumnal equinox? Autumnal equinox, two moments in the year when the Sun is exactly above the Equator and day and night are of equal length; also, either of the two points in the sky where the ecliptic (the Sun’s annual pathway) and the […]

What is the difference between a primary consumer and a secondary consumer and tertiary? The main difference between primary secondary and tertiary consumers is that primary consumers are the herbivores that feed on plants, and secondary consumers can be either carnivores, which prey on other animals, or omnivores, which feed on both animals and plants, […]

Is diorite volcanic or plutonic? It is produced in volcanic arcs, and in mountain building where it can occur in large volumes as batholiths in the roots of mountains (e.g. Scotland, Norway). Because it is commonly speckled black and white, it is often referred to as “salt and pepper” rock. Diorite is the plutonic equivalent […]

What kind of microscope can see a Tardigrades? Monocular Compound Microscope Can Tardigrades live in the human body? Despite their reputation, tardigrades aren’t entirely indestructible. They cannot survive the trip through the human digestive tract since our stomach acid disintegrates the flesh of the tardigrade without much trouble, so eating one wouldn’t do any harm. […]

What is the most germicidal wavelength of UV light? 260 to 265 nm What happens if thymine dimers are not repaired? The more you expose your skin to UV light, the more likely you are to get the very unlucky combination of thymine dimers in a cell that are not repaired and lead to cancer […]

Which is the formula for determining mode? Thus, the mode can be found by substituting the above values in the formula: Mode = L + h (fm−f1)(fm−f1)+(fm−f2) ( f m − f 1 ) ( f m − f 1 ) + ( f m − f 2 ) . What is the formula for […]
