The spring made of a steel and not of copper . Give reason |
| Answer» A good spring will be that in which a large restoring force is developed on being deformed. This in turn depends on the elasticity of the material of the spring. Since Young’s modulus for steel is more than that of copper, therefore the springs made of steel and not of copper. | |

Derive centre of mass? |
|
Answer» Sorry i think there are too many mistakes ? fist time i was typing ? One particle system or two particle system... I don\'t know about one particle system and i can\'t type the derivation of tow particle system it\'s leanthy and time consuming... So you can go to the pradeep\'s book on page no. 5/3 ..... It will help you, i think so ?? Derivation????? The point at which the mass of whole body is assumed to be concentrated is known as Centre of mass . |

SI unit of Gravitional Constant |
| Answer» F = Gm₁m₂/r²consider two bodies of mass m1 and m2 separated by distance r then force is directly proportional to the product of massses and inversly proportional to the square of distance b/w them after removing the proportionality we get a contant universal gravitational constants.i. units we can rearrang the formula toG = Fr²/ m₁m₂si units of force = N (newton) , r= m (meters)mass = kg (kilograms)substituting in the above eqn we getunits of G = Nm²/kg² or Nm²kg⁻²also dimensional formula = [M⁻¹L³T⁻²] | |

What is centre of mass? And Derivation of centre of mass? |
| Answer» \tConsider a body consisting of large number of particles whose mass is equal to the total mass of all the particles. When such a body undergoes a translational motion the displacement is produced in each and every particle of the body with respect to their original position.\tIf this body is executing motion under the effect of some external forces acting on it then it has been found that there is a point in the system , where whole mass of the system is supposed to be concentrated. The nature the motion executed by the system remains unaltered when force acting on the system is directly applied to this point. Such a point of the system is called center of mass of the system.\tHence for any system Center of mass is the point where whole mass of the system can be supposed to be concentrated and motion of the system can be defined in terms of the center of mass. | |

Explain SHM??? |
|
Answer» It is an oscillatory motion in which acceleration of body is directly proportional to its displacement from its mean position but in opposite direction. A harmonic oscillation of constant amplitude and of single frequency under a restoring force whose magnitude is proportional to the displacement and always acts towards mean Position is called Simple Harmonic Motion (SHM). |

Anyone derive venturimeter for me |
|
Answer» Yar how you add the diagram ??? Venturimeter\tVenturimeter is a device to measure the flow of incompressible liquid.\tIt consists of a tube with a broad diameter having a larger cross-sectional area but there is a small constriction in the middle.It is attached to U-tube manometer. One end of the manometer is connected to the constriction and the other end is connected to the broader end of the Venturimeter.The U-tube is filled with fluid whose density is ρ.A1= cross-sectional area at the broader end, v1\xa0= velocity of the fluid.A2=cross-sectional area at constriction, v2= velocity of the fluid.\t\t\tBy the equation of continuity, wherever the area is more velocity is less and vice-versa.As A1\xa0is more this implies v1\xa0is less and vice-versa.\tPressure is inversely ∝ to Therefore at A1\xa0pressureP1\xa0is less as compared to pressure P2\xa0at A2.\tThis implies P1 |
