The time rate of decrease of density of a moving fluid element (particle) of fixed mass as it passes through a given point in a flow field is−0.2 kg/m3 sec. the density of the fluid element at that point is 1.21 kg/m3. calculate the time rate of change of volume of this moving fluid element as it passes through the given point by two methods: (a) using just the physical geometry of the element, and (b) using directly the continuity equation in the form of equation +휌휌∇⋅푉푉�⃗=0.

How do the measurements of charge at the different locations on the sphere compare to each other? the charge measurements are different at all locations on the sphere. the charge measurements are virtually not the same at all locations on the sphere except for the charge at the very top and at the very bottom that are equal. the charge measurements are virtually the same at all locations on the sphere except for the charge at the very top. at the top, the conductive sphere has a small disk that is made of different material. the charge measurements are the same at all locations on the sphere. what happens to the charge on the conductive sphere when it is connected to a source of charge such as the electrostatic voltage source? nothing will happen because no charge goes around the surface of the sphere. the charge on the conductive sphere spreads out over the surface of the sphere; being greater in some specific locations on the sphere. the charge on the conductive sphere spreads out uniformly over the surface of the sphere. the charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.
