Why second law of motion is real law? |
|
Answer» We shall derive the 1st\xa0and the 3rd\xa0law of motion fron the 2nd\xa0law.Derivation of 1\xa0st\xa0law: According to Newton\'s 2\xa0nd\xa0law of motion,F = maWhere, F is the force applied, m is the mass of the body and a is the acceleration of the body.So, In absence of a force,F = 0⇒ ma = 0⇒ a = 0Since, m cannot be zero for a body.Zero acceleration means, body at rest will remain at rest and a body in uniform motion will continue its uniform motion. Which is Newton\'s 1st\xa0law of motion. Because it contains both first and third laws in it.. |

What is strong nuclear force |
|
Answer» The force whch hold together proton and nuetron in nucleus The Strong Nuclear Force is one of the four basic forces in nature. As its name implies, it is the strongest of the four. However, it also has the shortest range, meaning that particles must be extremely close before its effects are felt. Apparently, its main job is to hold together the subatomic particles of the nucleus. |

Explain the applications of Bernoulli\'s theorem |
| Answer» i) Lift of an aircraft wing: A section of an aircraft wing and the flow lines are shown in Fig. The orientation of the wing relative to the flow direction causes the flow lines to crowd together above the wing. This corresponds to increased velocity in this region and hence the pressure is reduced. But below the wing, the pressure is nearly equal to the atmospheric pressure. As a result of this, the upward force on the underside of the wing is greater than the downward force on the topside. Thus there is a net upward force or lift.(ii) Blowing of roofs: During a storm, the roofs of huts or tinned roofs are blown off without any damage to other parts of the hut. The blowing wind creates a low pressure P1 on top of the roof. The pressure P2 under the roof is however greater than P1. Due to this pressure difference, the roof is lifted and blown off with the wind.iii) Bunsen burner: In a Bunsen burner, the gas comes out of the nozzle with high velocity. Due to this the pressure in the stem of the burner decreases. So, air from the atmosphere rushes into the burner. | |

Prove that newtons second law of motion is real law of motion |
|
Answer» Derivation of 1 law of motion by using 2 law of motion--In the absence of external forceF=maF=0ma=0m is not equal to the 0a=0This proves the first law of motion Newton\'s second law of motion is the real law of motion because from this we can drive the first and third law of motion |

Physics ke liye ncert 11 level ke liye theek hai ki nhi for getting 90% |
|
Answer» U can score 85% with ncert textbook. For more u need to prepare from refernce books life sl arora,pradeep You can buy HC Verma or SL Arora if you want to study both competition and board N cert will just get you hardly 80% Ncert is best but you can\'t score 90 percent only with ncert you should buy another book to score 90 percent ☺ NCERT is not enough if u want to get 90% . You should use a reference book of pradeep or S L Arora for physics Ncert is not sufficient for class 11. You shous use a guide book of DC pandey Physics objective It contains Neet and jee\'s question ekdum sahi hai |

Define coefficient of limiting static friction |
|
Answer» the limiting coefficient of static friction may be different for different parts of the surface. In this case, there is no single choice of an average limiting coefficient of static friction. Rather, the limiting value of static friction that can be applied also depends on how the normal force is distributed across the different parts of the surface. If P denotes the pressure, then the limiting value of static friction is the integral over area element mu s Fast reply |

What is efficiency |
| Answer» Efficiency is a measure of how much work or energy is conserved in a process. In many processes, work or energy is lost, for example as waste heat or vibration. The efficiency is the energy output, divided by the energy input, and expressed as a percentage. A perfect process would have an efficiency of 100%. | |

Is there any end of the universe? |
|
Answer» ????? Yes,there is end : according to Einstein, black hole is increasing so their size also increase . Earth and galaxy will destroy but Einstein does not the equation of black hole because he died when he was working for this equation ,as a result he pridict only No. Universe is such a thing which don\'t have any end. Like our problems? No, bro.... Waise bhi aaj tak measure Kar k dekha nhi No No there is no end of universe |
