Calculate the range of a projectile - a motion in two dimensions. SI System An introduction to the SI metric system. Solar System Constants Properties and data for the Sun, the Earth and the Moon. Support Reactions - Equilibrium Static equilibrium is achieved when the resultant force and ...
In this study, we explore the structural and stability properties of anisotropic dark matter stars within the framework of gravity’s rainbow. By incorporating energy-dependent rainbow functions into the spacetime metric, we examine quantum gravitational effects on compact stars under extreme conditions....
Water weighs 1,000 kilograms per cubic meter, so taking the wood’s density (in metric units) and dividing by 1,000 yields its specific gravity in woodworking standards. Related Articles: Average Dried Weight Janka Hardness Top Ten Heaviest Woods Subscribe {} [+] 37 Comments brian 1 ...
In Sect. 6 we outline the links between the two methods (i.e., FT and anomaly based methods), through study of how the effective action transforms under a rescaling of the metric by a constant factor. A brief summary of results and related discussions are provided in Sect. 7. For the...
One interpretation of these values is that they give the probabilities for finding such metrics in the vacuum state. Another interpretation is that they give the contribution of that metric to the partition function for a grand canonical ensemble at a certain temperature, angular momentum, and ...
The phase angle could be very low in a set of candidate images if the sun is “at your back” in all of them, even though the incident angles are diverse. Adding solar azimuth and spacecraft azimuth to the metric helps to ensure a variety of illumination and viewing angles, but again ...
2. Self-Regular Holographic Screen A simple but intriguing model of singularity-free black hole has been "guessed" in [37], in the sense that the metric was assigned as an input for the Einstein equations. Sometimes this inverted procedure is called "engineering" because the actual source ...
Since we are interested in the cosmological evolution of the model, we derive the perturbation equations using the flat Friedmann–Robertson–Walker (FRW) metric in the Newtonian gauge \begin{eqnarray*} \mathrm{d}s^2 = (1+2\Psi) \mathrm{d}t^2 - a^2(t)(1-2\Phi)\gamma _{ij}\mat...
specific for the Robertson–Walker metric (1) in the scalar tensor representation. We note that these equations contain second order terms, describing a cosmological model where the matter-geometry interplay is mediated by the evolution of two additional scalar fields ϕ and ψ. As in the previo...
