. The force acting on an object of mass m travelling of velocity v in a circule of radius r is giving by f = mv 2 /r. The measurements recorded as m = 3.5kg ± 0.1 kg v = 20m/s ± 1m/s & r = 12.5m ± 0.5m find the maximum possible (i) fractional error (ii) percentage error in the measurement of force.

What is shear modulus

Posted by Ruchi Pandey 7 years, 10 months ago

CBSE > Class 11 > Physics

1 answers

Prince Jaat 7 years, 10 months ago

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

Posted by Dishu Soni 7 years, 10 months ago

CBSE > Class 11 > Physics

1 answers

Prince Jaat 7 years, 10 months ago

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).
