Explain the process of flying of a bird |
|
Answer» Answer: Basic mechanics of bird flight Lift force is produced by the action of air FLOW on the wing, which is an airfoil. The airfoil is shaped such that the air provides a net UPWARD force on the wing, while the movement of air is directed downward. The streamlining of bird's body and wings REDUCES these forces. *Hope this will HELP you. plz give me a THANK and follow me ✌. |

Ii m is equal to Q M Omega how it is coming |
|
Answer» Answer: The quantum harmonic oscillator is the quantum-mechanical analog of the classical harmonic oscillator. Because an arbitrary POTENTIAL can usually be APPROXIMATED as a harmonic potential at the vicinity of a stable equilibrium point, it is one of the most IMPORTANT model systems in quantum mechanics. Furthermore, it is one of the few quantum-mechanical systems for which an exact, analytical SOLUTION is KNOWN. |

8. In the arrangement shown, the mass m will ascend with anacceleration (Pulley and rope are (a)zero (b)g/5(c) g(d) 29 plz ans my this que fast |
|
Answer» Answer: hey LOOK let the T be the TENSION given in a question so T = 3 by 2 mg and we know that mg is pulling it down the the force ALSO needs to fight out with that of mg so T - mg = ma 3÷2 mg - mg = ma mg ÷ 2 = ma so from here we get a as g by 2 |

A machine of 2000 watt fill a tank in 10 minutes of mass 1000 kg at height 10m what is the efficiency of machine |
|
Answer» Answer velocity=2000 MASS=1000kg time=10min Explanation: in for according to newtons 3 law ACTION is always opposite to reaction. in this case velocity of WATT is 2000 means it's action. it's reaction means mass is 1000kg so we divide both first. by DIVIDING answer is 2 by 1 watt by multiplying 2x10 Is 20 the efficiency of MACHINE is 20watt |

What is meant by angular diameter of the moon. |
|
Answer» Angular diameter is the angle subtended at the EYES of the observer by the 2 end points of the diameter of the MOON at a particular INSTANT. It does not have any fixed value as when the distance between the moon and the EARTH is less than what it normally is, the angle subtended is larger than what it normally is! |

A body weighs 5.6kgwt on the surface of the Earth.How much will be it's weight on a planet whose mass is 1/7th mass of the Earth and radius twice that of Earth's radius. |
|
Answer» Answer: 0.2 N Explanation: MASS of Earth = M Mass of unknown planet = M' = M/7 Radius of earth = R Radius of unknown planet = R' = 2R Acceleration DUE to earth's gravity = g Acceleration due to unknown planet's gravity = g' Acceleration due to gravity at unknown planet is g' = GM'/R'² = G (M/7) / (2R)² = GM/(28 R²) = g/28 Mass of BODY = 5.6 / g Weight of body on unknown planet = MG' = 5.6/g × g/28 = 0.2 N |

A planet has mass 6.4×10*24kg and radius 3.4×10*6m.Calculate energy required to remove an object of mass 800kg from the surface of the planet to infinity. |
|
Answer» Answer: 126.1 MJ/kg Explanation: Mass of PLANET = 6.4×10^24 kg Radius = 3.4×10^6 m G = 6.7*10^(-11) Nm^2/kg^2 The gravitational potential at surface is: P = -(G*M)/r = - [6.7*10^(-11) × 6.4×10^24 ]/3.4×10^6 = - 12.61 × 10^7 = -1.261 × 10^8 J/kg P= -126.1 MJ/kg Now if 10MJ/kg work is DONE to LIFT a particle to some height from surface the potential will be -116.1 MJ/kg . So, the required work = 126.1 MJ/kg [raised to a height where gravitational potential reaches zero . From 0 to INFINITY it can not be measured ] |

Find the initial velocity of the particle in X direction vary with time given by? |
| Answer» | |
| 50. |
(a) Derive the formula : v = u + at, where the symbols have usual meanings. |
|
Answer» Consider a body of mass “m” having initial velocity “U”.Let after time “t” its FINAL velocity becomes “v” due to uniform acceleration “a”. Now we know that: Acceleration = CHANGE in velocity/Time taken => Acceleration = Final velocity-Initial velocity / time taken => a = v-u /t =>at = v-u or v = u + at This is the first equation of motion. |
