Advantages and limitations of wave energy |
| Answer» Renewable: The best thing about wave energy is that it will never run out. 2. Environment Friendly: Also unlike fossil fuels, creating power from waves creates no harmful byproducts such as gas, waste, and pollution.3. No Damage to Land : Unlike fossil fuels which cause massive damage to land as they can leave large holes while extracting energy from them , wave power does not cause any damage to earth.

Why does the colour of copper sulphate solition change when an iron nail is dipped in it? |
|
Answer» Because iron is more reactive than copper so iron displaces copper from copper sulphate and forms iron sulphate hence the colour of solutions change When an iron nail dipped in the copper sulphate solution than iron displaces copper from the copper sulphate because iron is more reactive than copper. Therefore the colour of the copper sulphate solution changes.The reaction involved isFe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s) |

What is difference between transfering electron and sharing of electrone |
|
Answer» We can say that transferring electron is ionic bond and sharing electron is said to be covalent bond In electron transfer, one atom actually takes an electron from another atom that is ionic bond, but in electron sharing, the one electron orbits both atoms, so they share the electron to make a strong bond together that is covalent bond like in water. |

Write definations of eco system |
| Answer» An ecosystem can be simply defined as a community of living beings in concurrence with nonliving components in which they will interact. It is a chain of interaction between organisms and its environment.An ecosystem can vary in size it can either be small as an oasis or vast as an ocean encompassing precisely limited spaces. They are usually controlled or influenced by external and internal factors as well. External factors such as climate can be considered as a prime material that forms soil and topography that controls the entire configuration of the ecosystem. | |

Where is embryosac found |
| Answer» Embryo sac is the structure which develops from the megaspore of the plant ovule. Embryo sac is also called as the female gametophyte. Embryo sac bears both embryo plant and the endosperm after fertilisation. There are seven haploid cells in the embryo sac. They include three antipodal cells, one central cell (formed by fusion of 2 polar nuclei), two synergid cells and one egg cell. | |

What is the working of electric motor and generator |
| Answer» Working of electric motor:\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\xa0\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 B1 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.Electric Generator\tThe axle is rotated such that it moves in the clockwise directions that is AB moves up and CD moves down.\tAccording to Fleming\'s Right Hand rule, the induced current is setup in the coil along B1-> AB -> BC -> CD -> B2. This means that the external current flows from B2 to B1.\tAfter half a rotation, arm CD starts moves up and AB moves down.\tAccording to Fleming\'s Right Hand rule, the induced current is setup in the coil along B2-> AB -> BC -> CD -> B1. This means that the external current flows from B1 to B2.\tThus after every half rotation of the coil, the current changes direction. This is called an AC current.\tAC current(Alternating current) : Changes its direction after equal intervals of time. It is easier to transmit this current over long distances due to lesser loses and hence this is the current that is supplied to our houses from the electricity department. | |

Distinguish between tropic and nastic movement????? |
|
Answer» Thanks dhiraj but this much is enough for me..... Thanks to all for giving such a useful answers Tropic movement is the directional movement while nastic movement is non directional movement. Tropic movements are directional movement whereas nastic movement is indirectional movement.in tropic movement the direction of response is determined by direction of stimulus .in nastic movement the direction of response is not determined by direction of stimulus. Do you understand ? If you understand this than it is good and if you not undrstand then tell me i will elaborate it with some examples. Movement of plant part in fixed direction is known as tropic movement but in nastic movement movement of plant is not fixed i.e. plant part move in radial direction . Tropismi. The direction of a stimulus determines the direction of the plant partsii. It is a directional movementNastici. Direction of movement of plant part is not determined by direction of stimulusii. It is not a directional movement |
