Hookes law |
|
Answer» Within elastic limit the extension on the wire is directly proportional to the force applied. Within elastic limit , stress is directly proportional to strain in elastic body. F(ext)=-kxF\\x=kSince acc. to this law external force is inversely proportional to x.(diß). |

What is shear modulus |
| Answer» SHEAR MODULUS The shear modulus is the elastic modulus we use for the deformation which takes place when a force is applied parallel to one face of the object while the opposite face is held fixed by another equal force. When an object like a block of height L and cross section A experiences a force F parallel to one face, the sheared face will move a distance ∆x. The shear stress is defined as the magnitude of the force per unit cross-sectional area of the face being sheared (F/A). The shear strain is defined as ∆x/L. The shear modulus S is defined as the ratio of the stress to the strain. | |

Calculate the degrees of freedom for monoatomic, diatomic and triatomic gas |
| Answer» The total number of independent modes(ways) in which a system can possess energy is called Degree of freedom.Monoatomic GAS The Molecules pf monoatomic gas can move in any direction in space so it can have three independent motions and hence 3 degree of freedom (all translational).Diatomic GAS A molecule of diatomic gas has five degrees of freedom (3 tanslational and 2 rotational).Triatomic GAS (non-linear) A molecule of non linear gas can rotate about any of three co-ordinate axes.Hence it has six degrees of freedom (3 translational and 3 rotational). | |
