5. A particle is acted upon by two forces F and G. The force F has magnitude 8N and actsin a direction with a bearing of 240°. The force G has magnitude 10N and acts due South.Given that R=F + G, find(i) the magnitude of R,(ii) the direction of R, giving your answer ...
We present an expression of radiation trapping forces acting on a multilayered spherical particle in a Gaussian beam by using the theory of electromagnetic momentum, and, as an example, numerical results are given to an axial two-layer absorbing spherical particle, along with a discussion about ...
We located the Hele–Shaw cell in a transparent decompression container to minimize the local pressure heterogeneity and controlled the ambient pressure (Fig.1). The Hele-Shaw cell made from two glass plates is separated by a small distanceDwith uniform spacers. We filled the cell with silicone ...
bubble diameter and shear stress are analyzed, along with the bubble coalescence and breakup mechanisms in relation to flow area for the 25.4mm and 50.8mm pipe diameters. The various forces acting on the bubbles are identified and related to the observed void profiles. The liquid velocity field,...
In the absence of external forces some single particle properties such as the diffusion and the mean square displacement have the same form in ABP31,39,40 and AOUP41. (ii) Both models undergo the so-called motility induced phase separation42,43,44,45. While such a topic has been well ...
when the distance is more than three times the cylinders' diameter, the higher Reynolds number has a smaller drag coefficient (as in the case of a sin... HC Vu,J Ahn,JH Hwang - 《Ksce Journal of Civil Engineering》 被引量: 9发表: 2016年 The in-line forces acting on an elastically...
The definition enforces gapless alignment between the input query and target sequences with the same length. The protein that provides the lowest S(Q, T) among all searching proteins is selected as the target protein, and the corresponding target peptide starts from number P(Q, T) in the ...
forces on each atom are below 10−2 eV/Å and the convergence of total energy is lower than 10−5 eV. The vacuum layer thickness is larger than 15 Å and the Brillouin zone was sampled by a set of 1 × 1 × 1 K-mesh. The transition dipole moment elements\(...
In addition, the surface tension acting at the edge of the foam causes the deforma- tion and the rearrangement of the bubbles. Thus the proposed experiment also enables us to investigate mechan- ical properties of the dry foam and the wet foam. Results Structural change of LG foam during a...
