How do you explain ionic bonding? Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion. […]

Is a 100 year old person old and 1000 year old artifact ancient? Answer: the hundred year old person is not ancient since alot of people can move up to a hundred years while the thousand year old artifact is ancient since alot of artifacts break early or a while but some will manage to […]

What are the 3 laws of force? In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other […]

Why bandwidth of digital signal is infinite? A true square wave has a vertical line for its face. That is, an increase from Vmin to Vmax in zero seconds. Anything (except zero) divided by zero is infinity. In reality it takes time for the voltage to rise from Vmin to Vmax, and so there is […]

Why does normal wire fail at microwave? Conventional wires can not carry microwaves because of the energy they give off; instead, coaxial cables can carry microwaves up to 5 GHz in frequency because their self-shielding conductors prevent radiating energy. Is the transmission of data by microwave radio waves? Microwave is a line-of-sight wireless communication technology […]

Can you see in mirrored glass at night? When can you see through mirrored window films? During daylight hours you will be able to see through mirrored window film from the inside out. If it’s brighter inside (usually at night when lights are on in the home) then it will be possible to see through […]

Where are land breezes the strongest? Land breezes are strongest along the immediate coastline but weaken considerably further inland. Land-breeze circulations can occur at any time of year, but are most common during the fall and winter seasons when water temperatures are still fairly warm and nights are cool. What breeze blows from land to […]

How are atoms linked? Molecule is the general term used to describe any atoms that are connected by chemical bonds. There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds. What are three parts of an atom? Our […]

What is the symbol for phase difference? (symbol: ϕ) The difference in phase between two sinusoidally varying quantities of the same frequency. What is meant by phase diagram? Phase diagram is a graphical representation of the physical states of a substance under different conditions of temperature and pressure. A typical phase diagram has pressure on […]

What is inductive method of teaching? An inductive approach to teaching language starts with examples and asks learners to find rules. It can be compared with a deductive approach that starts by giving learners rules, then examples, then practice. Learners listen to a conversation that includes examples of the use of the third conditional. What […]
