A magnetic field is produced when there is a current in the primary coil of a transformer.^^^^basically magnectic fieldA changing current in the primary-winding of a transformer produces a changing magnetic flux in the core which results in a back-emf. in the primary winding through self induction, and a voltage in the secondary winding due to mutual induction.
Both waves travel along Earth's surface and decrease in amplitude with depth below the surface.
well it depends is you are talking about a primary pollutant or secondary usuall if its primary it could be dust or anything that is naturally on this earth and if its a secondary anything that is man made its radon if your talking about an element Answer:Potential common basement air pollutants include: * Pet dander (Dry pet spit)* Pet hair * Dust mite feces * CO (From furnaces and heaters) * Ozone (from electrical equipment)* Radon (from drywall and granite)* Phenol (From cleaners and adhesives)* Chlorine (From bleach and bathroom cleaners)* VOCs (From solvents, rugs, paints, glue and cleaners* Formaldehyde (From urea formaldehyde insulations)* Styrene monomer (from styrene insulation)* Toluene (From paoinsts, sovets, glue)* Tobacco Smoke * Asbestos (From old insulation)* Fecal Matter/Fecal coliform bacteria (Toilet flush spray)* Peanut Fragments/dust (Fom snacks) * Selenium (From ant traps)
The atoms of both elements have seven valence electrons and a strong tendency to abstract, from a less electronegative atom, an electron to complete their valence shells and thereby become an anion.

The penguin is a secondary consumer because it consumes first order consumers. Its most common prey is fish which are primary consumers.
primary xylem is primary in nature & is derived from procambium. But secondary xylem is secondary in nature and derived from fascicular cambium and interfascicular cambium. Primary xylem is differentiated into protoxylem and metaxylem, but secondary xylem has no such differentiation. In primary xylem vessels and tracheids are long and narrow, and vessels don't have tyloses, but in secondary xylem, vessels are blocked by tyloses, and vessels and tracheids are wider and shorter. Xylem fibres are more abundant in secondary xylem , and found in small numbers in primary xylem. Also unlike in primary xylem, secondary xylem has differentiated into sapwood & heartwood.
Newspapers encyclopedias, dictionaries and textbooks are all examples of secondary sources .Another answerA secondary source can be explained most coherently by starting with the definition of a primary source:A primary source is written or created by a person. For example, Thomas Paine was the author of COMMON SENSE just as James Madison was one of the authors of THE FEDERALIST PAPERS.Those are primary sources.Any commentary, reference to, biography of the author which quotes or other wise uses these primary sources is a secondary source.Think of the primary source being a straight-on view, while a secondary source relates to the primary source obliquely.
Some of the causes of primary amenorrhea can also cause secondary amenorrhea.The most common cause of seconardy amenorrhea is pregnancy.The cessation of menstruation also occurs permanently after menopause or a hysterectomy.
if you mean what is the most common type of industry it depends on how developed countries are: More developed countries the most common is tertiary then quaterniary then secondary then primary less developed countries the most common is primar then secondary then tertiary than quaternary
both are the storage devices both store the data in binary form both are the costlier
First off, a battery is what you get when you stick several cells together, so for the most common 1.5 volts the strictly correct answer is that they are cells, not batteries. The 9 volt rectangular thingies though, they are batteries. Primary vs secondary is about rechargeable or not. A primary is not rechargeable, so a Duracell would most likely be a Primary cell.
They all have delta primaries and star secondaries, possibly earthed. The number is the angle of the secondary voltage's lag behind the primary's, expressed as an hour on a clock-face. 11 --> Secondary leads primary by 30 degrees 1 --> Secondary lags primary by 30 degrees 5 --> Secondary lags primary by 150 degrees, making the red secondary voltage lag the yellow primary by 30 degrees (using UK Red/Yellow/Blue phases) Dyn11 and Dyn1 are much more common than DYn5
A primary security is issued directly by a corporation to an investor. For example, a share of common stock issued directly by a company to you, an investor, is a primary security. A secondary security is one that is issued by a financial intermediary. For example, when you are investing in a mutual fund, you're investing in a secondary security - the issuing corporation sells its stock to the mutual fund, and you buy a share of the fund, not a direct share of stock from the issuing corporation. Some other examples of primary securities: Common stocks, corporate bonds, US Government bonds Secondary: Mutual Funds, money market funds, commercial paper, Certificate of Deposits
