Briefly explain the construction and working of a magnetic compass?

Answer»

a compass?The simplest compass is a magnetized metal needle mounted in such a way that it can spin freely. (You can make one yourself by magnetizing an ordinary needle, placing it carefully on a slice of cork, and letting the cork float in a tray of water.) Left to its own devices, the needle turns until one end points north and the other south. You can usually figure out which end is which from the position of the Sun in the sky, remembering that the Sun rises in the east and sets in the west. So if you're looking down on the floating needle at about noon, with the eye on the left and the point on the right, and the Sun in front of you, you know the point is indicating north.Construction of magnetic compassA magnetic compass has a flat circular aluminium box , at the base of which are marked directions like north , south , east and west. A suspended magnetic needle is PLACED in the center which can ROTATE freely . The north pole is if different colour to identify the north pole.The magnetic compass is the most familiar compass type. It functions as a pointer to "magnetic north", the local magnetic meridian, because the magnetized needle at its heart aligns itself with the horizontal component of the Earth's magnetic field.How do compasses work?Magnetism is one of the first bits of SCIENCE we learn in school and just about the first thing we discover is that "like poles repel, unlike poles attract." In other words, if you hold two bar magnets so their north poles are almost touching, they'll push away from one another; if you turn one of the magnets around so one magnet's north pole is near the other magnet's south pole, the magnets will pull toward one another.That's all there is to a compass: the red pointer in a compass (or the magnetized needle on your home-made compass) is a magnet and it's being attracted by Earth's own magnetism (sometimes called the geomagnetic field—"geo" simply means Earth). As English scientist William Gilbert explained about 400 years ago, Earth behaves like a giant bar magnet with one pole up in the Arctic (near the north pole) and another pole down in ANTARCTICA (near the south pole). Now if the needle in your compass is pointing north, that means it's being attracted (pulled toward) something near Earth's north pole. Since unlike poles attract, the thing your compass is being attracted to must be a magnetic south pole. In other words, the thing we call Earth's magnetic north pole is actually the south pole of the magnet inside Earth. That's QUITE a confusing idea, but it'll make sense if you always remember that unlike poles attract.Earth's magnetic field is actually quite weak compared to the "macho" forces like gravity and friction that really dominate our lives. For a compass to be able to show up the relatively tiny effects of Earth's magnetism, we have to minimize the effects of these other forces. That's why compass needles are lightweight (so gravity has less effect on them) and mounted on frictionless bearings (so there's less frictional resistance for the magnetic force to overcome).

Answer»

on number is the charge left on the central atom when all the BONDING pairs of electrons are REMOVED, with the charge devolved to the most electronegative atom. For Ni(CO)4, we break the Ni−CO bond and we get Ni0+4×−:C≡O+. And thus nickel has a formal oxidation state of ZERO.

Short note on public places and sanitation

Answer»

ion in public placesWhere a large number of people are using one area, such as a bus station or school, especially when they are eating food from the same source, there is a greater risk of the spread of diseases such as cholera, hepatitis A, typhoid and other diarrhoea diseases.These places vary in the number of people using them, the amount of time that people spend there and the type of activity that occurs in the area, but all public places need to have adequate sanitation and HYGIENE facilities.Special attention should be paid to the adequacy of facilities, their availability to the public, and the conditions of their operation.There are several basic rules for sanitation in public places:• There should be sufficient toilet facilities for the maximum number of people using the area during the day.• This normally means one toilet compartment for every 20 users. The toilet facilities should be arranged in separate BLOCKS for men and women. The men's toilet block should have urinals and toilet compartments; the women's block, toilet compartments only. The total number of urinals plus compartments in the men's block should equal the total number of compartments in the women's block.• Toilet facilities should not be connected directly to KITCHENS. This is in order to reduce the number of FLIES entering the kitchen and to reduce odours reaching the kitchen. It is important that people using the toilet facilities cannot pass directly through the kitchen.• There must be a hand washing basin with clean water and soap close to, the toilet facilities. There should be separate, similar facilities near to kitchens or where food is handled.• There must be a clean and reliable water supply for hand washing, personal hygiene and flushing of toilet facilities. The water supply should meet quality standards and be regularly tested to ensure that any contamination is discovered quickly and that appropriate remedial action is taken.• Refuse must be disposed of properly and not allowed to build up, as it will attract flies and vermin.Responsibilities for cleaning sanitation facilities should be very clearly defined. Dirty facilities make it more likely that people will continue to use the facilities badly or not at all. Clean facilities set a good EXAMPLE to users.It is important to make sure that information about health is available in public places. Such information should be displayed in an eye-catching, simple and accurate way. Where appropriate, large posters with bright colours and well-chosen messages, put up in obvious places, are effective.Health and hygiene messages may be passed on to the public using such posters in public places. These messages should include the promotion of:-• Hand washing.• Use of refuse bins.• Care of toilet facilities.• Protection of water supplies.Local school children and college students can be involved in preparing educational posters and notices for public places.

what is chromatography how will you separate of black ink using chromatography write any two application

Answer»

ography is a method used to separate components of a MIXTURE. In the case of black ink, put a dot of ink about 3 cm from the end of a strip of CHROMATOGRAPHY paper. Place the first .5 cm of the end of the strip in a solvent such as an alcohol. As the liquid alcohol climbs up the paper strip, it drags along the components of the ink, the more soluble components (pigments) will travel FURTHEST on the strip, the least soluble pigments will trail BEHIND resulting in the SEPARATION of the pigments.

Please solve it in 60-70 words

Answer»

jects are electrically neutral. This means that they have an equal positive and negative charge, each canceling the other out. In order to charge an object you have to ALTER the balance of negative and positive one way or the other. There are three ways to do this.There are three ways to charge an object: friction, conduction and induction. Friction involves rubbing on material with another, resulting in ELECTRONS MOVING from one surface to another. Most people have experimented with this form of charging an object, either rubbing a BALLOON on a jumper to make it cling or by shuffling their feet over a carpeted surface to build up an electrical charge to shock someone. Friction is useful for charging insulators, which are materials that aren't good conductors. Conduction on the other hand is used to charge things that are good conductors, such a metal. A charged object is touched to the conductive material and some of the charge, whether it is positive or negative, will be transferred. The final way to charge an object is by induction and is, again, best for conductive materials. The uncharged conductive material is grounded on any neutrally-charged material and the charged object is held near it. The charge will flow between the two objects and the uncharged conductor will develop an opposite charge to the original charged object.
