Prove that steel is more elastic than rubber |
| Answer» As we know youngs modulus is inversly proprtional to delta length.less deformation then high elasticity.hence elasticity of rubber<br>Elongation ot steel is less compared to rubber.so according to definition steel is more elastic than rubber<br>As elongation in rubber is more than steel .so it will take more time to regain its original confurigation than steel .As steel is a rigid body it inter molecular force of attraction between molecules of steel is more in that of rubber . Therefore, steel is more elastic than rubber<br>In steel strain is less than in rubber ball n elasticity is indirectly proportional to star in that\'s why less strain high elasticity | |

Derivation of stoke law |
| Answer» Stokes\' law defines the drag force that exists between a sphere moving through a fluid with constant velocity. Viscosity is the resistance of a fluid to flow, and with increasing viscosity, the sphere\'s velocity drops. When the radius of the sphere increases, the drag force increases too. | |

What is the difference between stress and tension |
| Answer» Tension defines a force that acts axially when an object is pulled on both sides. As it is a force, it has units of pounds or Newtons depending on the types of units you are using. Stress is a result of a force being applied to an object. When the object is loaded with a force, internal components of the object apply internal forces to one another. This effectively deforms the object. Stress, although a result of an applied force, is measured in units of pressure, which is pounds per square inch or Newtons per meter squared.Stress can actually result from tension forces since tension is an applied forces. | |

what is Boyle\'s Law? |
| Answer» Sorry, it\'s PV= P1V1=P2V2=K<br>Boyle\'s law states that, at constant temperature , the volume of a gas is inversely proportional to its pressure.V∝1/p or PV=K. Here, K is a constant. Its value depends upon the nature of the gas, mass of the gas and temperature.P =P1V1=P2V2=K<br>Boyle\'s Law simply describes the relationship between the pressure and volume of an enclosed gas when Temperature remains constant. That relationship, usually expressed as P1V1 = P2V2, just means that the product of pressure x volume remains unchanged as either or both are changed.<br>The volume of a given mass of a gas is inversely proportional to its pressure at constant temperature.V ∝ 1 / p or Vp = KK is a constant and its value depends on mass, temperature and nature of gas.∴ p1V1 = p2V2 | |

What is latent heat of vapourisation |
| Answer» The amount of heat energy required to change 1 kg of liquid to gas at its boiling point at a constant atmospheric temperature is called latent heat of vapourisation. Steam at 373 degree k contains more heat energy in the form of latent heat of vapourization. This causes more burns than boiling water at the same temperature<br>A good answer.... ?<br>The amount of heat required to change the state of unit mass of substance from liquid to vapour at its boiling point is called laten heat of vaporisation. | |

Water is more elastic than air. Why? |
| Answer» Because water bulk modulus is greater than air<br>Yeah correct..<br>We know that volumetric elasticity is a reciprocal of compressibility. Since air is more compressible than Water that is why water is more elastic then air.<br>Both water and air are fluid... But for the case of elasticity,, It\'s may that water has more intermolecular force of attraction blw particles than air ..... Soo... | |

Give stokes law by dimension method |
| Answer» Dimensional analysis proof of Stokes\' LawSuppose that the sphere has radius r and falls through a fluid of viscosity η. Let the terminal velocity be vWe can calculate the viscous drag F on the sphere by dimensional analysis. IfF = krxηyvz We have MLT-2 = Lx(ML-1T-1)y(LT- 1)zSolving this gives x = 1, y = 1 and z = 1. By other methods k can be shown to be 6π.Thus giving:F = 6πηrv | |

Why law of thermodynamics starts from zero? |
| Answer» Ohh ok<br>Yah... But I have bit confused in list manipulation and sorting... ?<br>But our scl is too late<br>Ohh ur school is quite fast<br>Boolean logic was completed by the starting of Oct....<br>Yah.. Python is going quite good.. According to our syllabus... By the mid of December.. Our python was will be finish...<br>It is called the zeroth law because it came to light after the first and second laws of thermodynamics had already been established and named, but was considered more fundamental and thus was given a lower number zero. | |
