Answer:
The general equation of movement in fluids is obtained from the application, at fluid volumes, of the principle of conservation of the amount of linear movement. This principle establishes that the variation over time of the amount of linear movement of a fluid volume is equal to that resulting from all forces (of volume and surface) acting on it. Expressed in This equation is called the Navier-Stokes equation.
The equation is shown in the attached file
Explanation:
The derivative of velocity with respect to time determines the change in the velocity of a particle of the fluid as it moves in space. It also includes convective acceleration, expressed by a nonlinear term that comes from convective inertia forces). With this equation, Stokes studied the motion of an infinite incompressible viscous fluid at rest at infinity, and in which a solid sphere of radius r makes a rectilinear and uniform translational motion of velocity v. It assumes that there are no external forces and that the movement of the fluid relative to a reference system on the sphere is stationary. Stokes' approach consists in neglecting the nonlinear term (associated with inertial forces due to convective acceleration).
Answer:
a)
Explanation:
As the visible light, infrared and radio waves are all electromagnetic waves with different frequency and wavelength, all of them propagate through the space at the same constant speed which is the speed of light in vacuum, as they meet the following equation:
c = λ*f
Mixtures are separated in a centrifuge
according to their densities
Greater speed and mass require
greater centripetal force
Traveling in a circular path with a smaller radius of curvature requires
a greater centripetal force
