Which rule do you use to find the direction of force |
| Answer» Fleming’s left hand rule gives us the force experienced by a straight current carrying conductor placed in a magnetic field perpendicular to it.The rule states that, stretch the forefinger, the central finger and the thumb of the left hand mutually perpendicular to each other. If the forefinger points in the direction of the magnetic field, the central finger in the direction of current, then the thumb points in the direction of force in the conductor. | |

Why freely suspended magnet come to rest in north-south direction |
|
Answer» when magnets are freely suspended and came to rest then there is no other force except magnetism is applied on that object .this magnetic force is due to earths rotation and this magnetic force is devided into two depending on poles and when a magnet came to rest than north pole attracts southern tip of magnet and south pole will attract northern tip of that following magnet Magnet which cause a freely suspended magnet to point always in a particular point:-North n south. The south pole of the earth\'s magnet is in the geographical north bcz it attracts the north - pole of the suspended magnet n vice versa.....:-) |

What are molecular movements needed for life? |
| Answer» Living organisms have well organised structures,they have tissues, tissues have cells, cells have other small components and so on. But due to environmental effects, this organised nature of living structures is likely to break down. If this ordered nature breaks down, then the organism will die. So living organisms must repair and maintain their structures. Since, all these structures are made up of molecules, so there should be molecular movement which is needed for life. | |

Describe double circulation |
| Answer» Double circulation: In human beings the blood goes through the heart twice during each cycle i.e., the blood passes through the human heart two times to supply once to the whole body. So, it is called double circulation of blood.The double circulation of blood includes(i) Systemic circulation and(ii) Pulmonary circulation(i) Systemic circulation: It supplies oxygenated blood from left auricle to left ventricle. Thereby pumped to various body parts. The deoxygenated blood is collected from the various body organs by the veins to pour into vena cavae and finally into right atrium (auricle). Right atrium transfers the blood into the right ventricle.(ii) Pulmonary circulation: The deoxygenated blood is pushed by the right ventricle into the lungs for oxygenation. The oxygenated blood is brought back to left atrium of the human heart. From left atrium the oxygenated blood is pushed into the left ventricle. The left ventricle pumps oxygenated blood into arota for systemic circulation. | |

Plz explain me series combination |
|
Answer» Resistance ie connected end to end series combination is a type of electric circute in which resistors are connected one by one . in this type of circute resistance is very much high and we cannot run a single applience this means that if turn ON switch than all aplience will start working at the same time if we turn OFFswitch then all applience will stop working . therefore we can not run a single resistance seperately .these all are some of the disadvantages of series combination |

Which is more accurate - Ammeter or Voltmeter? |
| Answer» Image result for which is more accurate ammeter or voltmeterVoltmeters draw some extra current, whereas ammeters reduce current flow. Null measurements balance voltages, so there is no current flowing through the measuring device and the circuit is unaltered. Null measurements are generally more accurate but more complex than standard voltmeters and ammeters. | |

What is the process of respiration in human being |
| Answer» Respiration is the set of events that results in the exchange of oxygen from the environment and carbon dioxide from the body\'s cells. The process of taking air into the lungs is inspiration, or inhalation, and the process of breathing it out is expiration, or exhalation.Air is inhaled through the mouth or through the nose. Cilia lining the nose and other parts of the upper respiratory tract move back and forth, pushing foreign matter that comes in with air (like dust) either toward the nostrils to be expelled or toward the pharynx. The pharynx passes the foreign matter along to the stomach to eventually be eliminated by the body. As air is inhaled, the mucous membranes of the nose and mouth warm and humidify the air before it enters the lungs. | |
