What is primary pollution?
Pollution is any foreign substance present in more concentration than safer limits. They are two types of pollutants 1. Primary pollutants 2. Secondary pollutants Primary pollutants are those which generated directly from Source . That type of pollution is generally termed as primary pollution. Ex : Carbondioxide , Sulphur dioxide etc in case of Air pollution Secondary pollutants are those which formed by the combination of more than two or more primary pollutants Ex : Ozone , Photo chemical smog in case of air pollution
Why does Secondary succession happen more frequently than primary succession?
Secondary succession happens more frequently than primary succession because the disruption to the environment is usually less severe in secondary succession, making it easier for organisms to recolonize the area. Additionally, the soil in secondary succession is usually already present, allowing for quicker establishment of plant life. This results in a faster and more common occurrence of secondary succession compared to primary succession.
Is acid rain a primary air pollution?
Acid rain is not a primary air pollution, in fact it should more correctly seen as a water or soil pollution problem. It is caused by sulfur oxides (SOx) and nitrogen oxides (NOx), which are primary pollutants, being washed out of the air by rain, snow or mists and he resultant acid solution being precipitated onto soil or into watercourses and water bodies.
How do pollutants affect the atmosphere?
Air pollutants (depending on the pollutant in question) absorb or reflect solar radiation or thermal radiation from the Earth. They also form "seeds" on which water droplets or ice crystals can form causing changes in cloud cover or precipitation. Pollutants can be poisonous to plant and animal life.
Difference between primary and secondary clay?
primary clay:- once formed from the parent rock deposited at origin, so less impurities,coarse particles,less humic acid , low plasticity& low shrinkage than 2ndry claysecondry clay:- 2ndry clay are transported and formed, so more impurities, fine particles, more humic,higher plasticity and shrinkage.

What are the functions of primary and secondary groups?
A primary group has fact to face interactions and is more intimate than secondary groups. Secondary groups are more formal.
Can you use secondary memory in place of primary memory?
No, Because secondary takes more time as compared to primary. primary takes less time as compared to secondary.
Which is more rapid primary or secondary immune response?
Secondary Immune Response is more rapid.
Are primary sources or secondary sources more valuable to modern historians?
secondary
What is the probability that your water will be polluted?
The probability is close to 100%. The more important question is the extent of pollution and how harmful those pollutants are. The answer to that depends on where in the world the question is about.The probability is close to 100%. The more important question is the extent of pollution and how harmful those pollutants are.

Formula for relation between primary winding and secondary winding?
The turns ratio of Primary / Secondary tells you have the voltage and current will be changed. The secondary current will be (primary turns/secondary turns) times the primary current, and the secondary voltage will be (secondary turns / primary turns) times the primary voltage.CommentThe above answer is a little misleading, because the secondary current is determined by the load, and not by the transformer's ratio. It would, therefore, be more accurate to say that the primary current would be equal to the secondary current times the (primary turns/secondary turns) -i.e. not the other way around!
Compare secondary and primary.?
primary is what some call younger or inexerienced level {beginner} and secondary is senior or professional or more experienced level
What is the difference of primary smoking and secondary smoking?
The difference between primary and secondary smoking is very simple. Primary smoking is actually smoking the cigarette yourself, whereas secondary or second hand smoking is inhaling fumes of other smokers around you, whilst you are not actually smoking the cigarette. That is why the smoking ban was introduced and more and more smokers are smoking in smoking shelters. Which, not only provides shelter for them when they are smoking outside, but it also protects non smokers from the harmful fumes.
Why is the number of turns in primary coil more than that of the secondary coil?
The number of turns or windings of a transformer can vary. There can be more in the primary, or more in the secondary, or there can be an equal number in a transformer that is simply used for isolation (an isoformer). More turns in the primary than secondary will create a step down transformer. More turns in the secondary are found in a step up transformer. The transformers on power poles have more turns in the primary to step the line voltage down for delivery to residential customers.
Is cherry primary or secondary source?
Its a primary source as it comes off a tree - cant get more primary than that
Compare primary and secondary division?
primary is what some call younger or inexerienced level {beginner} and secondary is senior or professional or more experienced level
