A particle starts from a point with a velocity of 6 metre per second hand moves with acceleration of 2 metre per second square so that after 6 seconds the particle will be at the starting point |
|
Answer» Acceleration = Change in velocity ÷ time In our case acceleration = 2 Our initial velocity = 6 We want to find the final velocity V Our time is 6 6 = (V - 6) / 6 36 = V - 6 42 = V V is thus 42 m/s |

Explain electromagnet im about 100 words |
|
Answer» An electromagnet is a TYPE of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of WIRE wound into a coil. A current through the wire creates a magnetic field which is CONCENTRATED in the hole in the center of the coil. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagneticmaterial such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet. |

A thick wire and a thin wire the same material are successively connected to the same circuit to find their respective resistance. which one will have lower resistance? give reason. |
|
Answer» R=p (l/a) where R is resistance ,p is resistivity ,l is length ,a is area As length is same so the thick wire will have more area hence LESS resistance as resistance is inversely proportional to area by above expression So your answer THIN wire will have more resistance DUE to less area |

Why do we use metals to make kettles ,boilers and boiler tubes? |
|
Answer» A boiler is a closed vessel in which fluid(GENERALLY water) is heated. The fluid does not necessarily boil. (In North America, the term "FURNACE" is normally used if the purpose is not to boil the fluid.[citation needed]) The heated or vaporized fluid exits the boiler for use in various processes or heating APPLICATIONS,[1][2]including water heating, central heating, boiler-based POWER generation, cooking, and sanitation. |

Explain the lateral shift and also write it's formula ? |
|
Answer» When a denser medium is kept between two parallel faces INSIDE a RARE medium and a ray falls UPON one of the two parallel faces reflects into the denser medium and COMES out of ANOTHER surface becoming parallel to the incident ray. In the successive reflection the deviation at first surface is reversed at second surface but the emergent ray deviates literally. The distance to what an emergent Ray devited from the direction of incident ray when suffers refraction at two parallel surfaces is called as lateral deviation/ displacement. The lateral displacement/deviation increase with the increase in • thickness • angle of incident • optical density |
