We obtain the equation of motion for GW on a 4D curved spacetime which has the form of a Fierz–Pauli one. In our model the mass of gravitons mg is induced by a static foliation on the noncompact space-like extra dimension and the source-term is originated in the interaction of the ...
What is an example of a force in physics? The most common examples of forces are gravitational and normal forces. Gravitational force is a non-contact force and is an attractive force between two objects with mass. For example, Earth exerts a gravitational force on the Moon. Normal force is...
step 3: Introduce these relations in the mass conservation law and average over film thickness. Wall boundary conditions are needed for steps 2 and 3. They influence the resulting Reynolds equation. Conditions of “no slip at the wall” are usually introduced in the model in step 2. To our...
If the volumetric flow rate was given, the mass flow can be found by multiplying the density of the fluid with the volumetric flow rate: Q * density. What is the formula for volume flow rate? The volume flow is the change in volume per change in time: dV/dt = (V_2 - V_1)/(t...

(6.3.5) forl=1gives the most optimal choice of the post-Newtonian center of mass for each body. This is because after differentiatio...
The Laplace equation is a mixed boundary problem which involves a boundary condition for the applied voltage on the electrode surface and a zero-flux condition in the direction normal to the electrode plane. From: Computer Aided Chemical Engineering, 2019 ...
