According to stokes law the backword viscous force acting on a small spherical body of radius r moving with uniform velocity v through fluid of viscosity eta n is given by.

Maunisha Mallan 7 years, 2 months ago

according to stoke's law, when a sperical body moves through a fluid,it experiences a viscous force.An expression for the viscous for force experienced by the spherical object was derived by stokes..therefore the expression is called stoke's law... where F=6^nrv...^=pi nd n=coefficient of viscosity

Lavanya ❤️? 7 years, 2 months ago

The magnitude of viscous force developed when a body is travelling through the viscous medium is said to depend on coefficient of viscosity, radius of the body and its terminal velocity given by F = 6 π a η v This equation is called Stokes' law.

Thanks Lavanya

Lavanya ❤️? 7 years, 2 months ago

As the vectors AB, BC, CD, DA form a quadrilateral, their resultant is zero. AB + BC + CD + DA = 0 Therefore the sum of vector is BC+CD+CA=BA. So BA+BC+CD+DA= BA+(BC+CD+DA) = BA +BA=2BA Therefore the value of n is 2

Ax= x component of A Ay = ycomponent of A Az = z component of A Therefore A= ( ax^2+ay^2+az^2)^1/2 It is for 3d For 2d only take x and y component Direction: Tan A = ax/ay

Work done in engine is a example of cyclic process

Akanksha Kumari? 7 years, 2 months ago

Work done in engine is also a example of circular motion and there is work done

Akanksha Kumari? 7 years, 2 months ago

I think here some kind of work is done And w=nR (ti-tf) Where N= no of moles R= gas constant Ti -tf= change in temperature

Moment of inertia is used in rotational motion just like mass is used in translational motion whereas law of inertia is tendency of a body to resist change in motion

Prakhar Jadaun ? 7 years, 2 months ago

In a easy way we can say that Moment of inertia is the rotational analogues of mass whereas law of inertia is a common name of Newton's 1st law....

Theorem of perpendicular axes-The moment of inertia of planer body about an axes perpendicular to the plane is equal to the sum of the moments of inertia(m.i) about two perpendicular axes concurrent with perpendicular axes and line in the plane of the body.(Izz'=Ixx'+ Iyy') about Z-axes.and now,Theorem of parallel axes -The m.i of a body about any axes is equal to the sum of the m.i of body about a parallel axis passing through it centre of mass and the product of its mass and square of the distance between two parallel axes.(Ic+mass of body*square of distance b/w axes).

For an adiabatic process of ideal gas equation we have PVγ = K (Constant) Where γ is the ratio of specific heat (ordinary or molar) at constant pressure and at constant voluume γ = Cp/Cv Suppose in an adiabatic process pressure and volume of a sample of gas changs from (P1, V1) to (P2, V2) then we have P1(V1)γ=P2(V2)γ=K Thus, P = K/Vγ Work done by gas in this process is W = ∫PdV where limits of integration goes from V1 to V2 Putting for P=K/Vγ, and integrating we get, W = (P1V1-P2V2)/(γ-1) In and adiabatic process if W>0 i.e., work is done by the gas then T2< T1 If work is done on the gas (W<0) then T2 > T1 i.e., temperature of gas rises

Elastic behaviour of solid is a force acting on a body instead of producing a change in its state of rest or of uniform motion, produces a change in the shape of the body. Such a force is called deforming force.

Aman Kumar 7 years, 2 months ago

A solid which can easily regain its original shape and size after applying some force on it.....This behaviour of solid is called elastic behaviour..
