Scientists say new research confirms results of an earlier study suggesting the crash of a spacecraft into an asteroid changed the shape of the targeted object. 科学家表示,新的研究证实了早期研究的结果,即航天器撞击小行星改变了目标物体的形状。 The latest research follows another recent study exam...
Determine if the shape is an irregular polygon. The perimeter of an irregular polygon is l1+l2+l3+...+ln, where each "l" variable is the length of a side and "ln" is the length of the last, or "nth," side. There are multiple ways to find the area of an irregular polygon. The...
The geometry and the electronic structure of the supramolecular complex was visualized by performing DFT calculations at the B3LYP/3-21G(*) level. In the optimized structure (Fig. 10), the two ZnP rings were aligned in a V-shape with an angle of 70°. No steric hindrance was observed. Th...
Describe the bonding in silicon in terms of hybrid orbitals. An electron is most delocalized in a(n) orbital. a. atomic b. bonding molecular c. anti-bonding molecular d. delocalization is equal between...
(a) Describe Rutherford's gold foil experiment. (b) How did the experiment prove that the plum-pudding model of the atom was wrong? Atomic Model: Theoretical models, along with associated theories proposed in order to explain the structure...
the Stokes drift current, wind-induced current, and current at breaking position. The wind approached from N to W, with values ranging from 2.4 to 3.8 m/s. The propagated significant wave height ranged from 14 to 21 cm, with an associated period of 3 s. Items with a positive buoyancy ...
