How is potential difference created |
|
Answer» Unequal balance on both terminal. Like water always flow from higher conc. to lower conc. And flows as much as until both side have same conc. So charge flow from 1terminal to another since until both terminals has same amount. Simply we can say that potential difference tb create hota h jb charges ka amount unequal hota h. And Charges ko ek dusri taraph jane se jo work hota h use hi elctro potential kahte h By creating difference between the two points |

Write the function of plant and animal harmone???? |
| Answer» Hormones are chemical substances produced within an animal or a plant which act as "chemical messengers" as means of communication among various parts of an organism. They help these parts function in a coordinated way. Hormones control such body activities as growth, development, and reproduction.(i) Plant hormones are simple organic substances and animal hormones are complex organic substances.(ii) Plant hormones are transported through xylem, phloem or by diffusion and animal hormones are transported in the blood.(iii) No specific organs are involved in the synthesis of the plant hormones, whereas animal hormones are always synthesized in endocrine glands. | |

Expalin fleming\'s right hand rule |
|
Answer» Fleming\'s right hand rule Strech your thumb,fore finger and middle finger of your right hand. Now your thumb represent motion or force fore finger represent magnetic current and middle finger represent current. Fleming\'s right-hand rule (for generators) shows the direction of induced current when a conductor moves in a magnetic field. It can be used to determine the direction of current in a generator\'s windings.When a conductor such as a wire attached to a circuit moves through a magnetic field, an electric current is induced in the wire due to Faraday\'s law of induction. The current in the wire can have two possible directions. Fleming\'s right-hand rule gives which direction the current flowsThe right hand is held with the thumb, first finger and second finger mutually perpendicular to each other (at right angles).· The thumb is pointed in the direction of motion of the conductor.· The first finger is pointed in the direction of the magnetic field. (north to south)· Then the second finger represents the direction of the induced or generated current (the direction of the induced current will be the direction of conventional current; from positive to negative) |

Explain briefly about the working of an electric motor with a schematic diagram. |
|
Answer» Itna bda ans iss app me kaise likhte ho \tWhen electric current is passed into the rectangular coil, this current produces a magnetic field around the coil.\tThe magnetic field of horse shoe-type magnet then interacts with the magnetic field of the coil and causes the coil to rotate continuously.\tIf ABCD is in horizontal position current from battery enters the coil through brush B1, and commutator half ring C:. The current flows in the direction ABCD\tand leaves via ring and brush B2\tThe direction of current is from A to B, the direction of current is from C to D. The force on side AB of the coil is in the downward direction. Whereas the force on the side CD of the coil is in the upward direction. ABCD rotate in anti-clockwise direction.\tWhile rotating when the coil reaches vertical position then the brushes\xa0B1 and B2 will touch the gap between the commutator rings and current to the coil is cut off. But the coil does not stop rotating because it has already gained momentum.\tThe coil CD comes on the left side and AB comes to the right side. Again they come in contact with brush B1 Current direction is reversed.\tThe reversing of current in the coil is repeated after every half rotation due to which the coil continue to rotate as long as current from the batter is passed through it. The rotating shaft of electric motor can drive a large number of machines which are connected to it.\t How work this electric motor |

Define left hand thum rule |
|
Answer» When we stretched fore finger,middle finger and thumb of left hand in such a way that they are matually perpendicular.Fore finger indicates the direction of magnetic field and middle finger indicates the direction of current and the thumb indicates the direction of motion or force in the conductor. Right hand thumb rule State that if we hold the conductor in the right hand such that the thumb point in the direction of electric current, than the direction in which the fingers curl gives the direction of magnetic field |

What is froth flotation method |
| Answer» This method is employed for the concentration of sulphide ores. The finely powdered ore is added to water in a tank containing pine oil. The mixture is agitated by blowing a blast of air. The ore particle preferentially wetted by oil come to the surface with froth while impurities which are wetted with water become heavier and settle at the bottom. The oil froth containing mineral particles which floats on froth containing mineral particles which floats on the surface of the water can be skimmed off easily.Ex : The concentration of copper pyrites, galena are done by this method. | |
