1.A number or symbol multiplied with a variable or an unknown quantity in an algebraic term, as 4 in the term 4x,orxin the termx(a+b). 2.A numerical measure of a physical or chemical property that is constant for a system under specified conditions, such as the coefficient of friction...
Velocity=dXdt=X=−ωX0sin(ωt)Acceleration=d2Xdt2=X=−ω2X0cos(ωt) Inserting the above expression for acceleration, or d2X/dt2, into the equation for Fs yields the following: Mgcd2Xdt2+KX=0−Mgcω2X0cos(ωt)+KX=0−Mgcω2X+KX=−Mgcω2+K=0 Solving this expression for ω...
The implications of (4.1) for the fluid velocity field may be better displayed by using Reynolds transport theorem (3.35) with F = ρ and b = u to expand the time derivative in (4.1): (4.2)∫V(t)∂ρ(x,t)∂tdV+∫A(t)ρ(x,t)u(x,t)⋅ndA=0. This is a mass-balance ...
But due to their large thermal velocity slightly smaller than that of active neutrinos , they would behave as Warm Dark Matter and erase small-scale cosmological structures. Their mass can be bounded from below using Lyman-α forest data from quasar spectra and from above using X-ray ...
Once you have started the boulder rolling, it develops momentum, which is defined by its mass and velocity. 出自-2015年12月阅读原文 In terms of efficiency and cleanness, buses, trains and other form of public or mass transportation are superior to the private automobile. 出自-2015年12月听力原...

It has been argued that the magnetic Maxwell stress leads to an advective term in the angular momentum transport equation, which could aim to drive the system towards uniform specific angular momentum instead of uniform angular velocity [156]. The diffusivity, whether produced directly via Maxwell ...
Thus, the shear stress is proportional to the velocity gradient. The proportionality factor μ is called the dynamic viscosity coefficient (or just dynamic viscosity). The kinematic viscosity of a fluid is the ratio of the viscosity to the density: (2.35)ν=μρ A fluid for which the viscosit...
