What is the differentiation of dy/dx ,y=1/root x |
|
Answer» And ^ means raise to Put the value of y in dy/dxd(1/root x)/dx=d(1/x^1/2)/dx=d(x^-1/2)And then apply the formulaAnd answer is , - 1/2x raise to the power 3/2 The differentiation of dy/dx= -1/(root x) ^2 = - 1/x ...... Hope this helps |

Can anyone help me in understanding laws of motion\'s basics |
| Answer» Three Laws of Motion:-----(1.) First Law, when an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their states of motion unless a force acts to change the motion.(2.) Second Law, In an innertial refference frame, the vector sum of the forces (F) on an object is equal to the mass (m) of that object multiplied by the acceleration (a) of the object F=ma. ( It is assumed here that the mass (m) is constant. )(3.) Third Law, When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body. | |

What is Vander Wall equation |
|
Answer» The vander waals equation of state approaches the ideal gas law PV=nRT asthe values of these constant approach zero. The constant a provides a correction for the intermolecular force. Constant b is a correction for finite molecular size and its value is the volume of one mole of the atoms or molecules. OR The vander waals equation was proposed in the year 1873. It was first step towards taking into account interaction forces which are acting between real gases molecules. The equation of state of the perfect aes refers to a gas consisting of point like items which do not interact with one another. Instead of this vander waals proposed an equation -------- (v-b)[p+a/v^]=RT where a and b are called vander waals constant and which have different value for each gas. (p+a/v^2)(v-b)=RT ....... I M NOT SURE... ? |

What is the dimensional formula of Young\'s modulus ......??? |
|
Answer» Wlc Ishu ?? Thanks Aman.....? Youngs modulus = ML^-1T^-2 Thanks yaar.... Young\' Modulus = stress/strain = F/A×e/l =ma/A×e/lWhere, F is force, A is area of cross section, e is elongation, l is actual length, a is acceleration, m is mass.By their units,Y= [(Kg×m/s ki power 2)]/[(m)ki power 2×m/m)]Y=(kg×m)/(m ki power 2 × s ki power 2)Y=kg/m×s ki power 2Therefore, dimensional formula of young\'s modulus is [ML^S*].《where ^ = -1 and * = -2.》☺☺ |
