Answer:
Nuclear properties
Naturally occurring beryllium, save for slight contamination by the cosmogenic radioisotopes, is isotopically pure beryllium-9, which has a nuclear spin of 3/2.Beryllium is alloyed with copper or nickel to make springs, gyroscopes, electrical contacts, spot-welding electrodes and non-sparking tools, according to the Royal Society of Chemistry. Other beryllium alloys are used in high-speed aircrafts and missiles, as well as spacecraft and communication satellites.

Answer : Option C) The polar bonds are oriented in opposite direction.
Explanation : A molecule of carbon dioxide 
contains two polar covalent bonds. This molecule is non-polar because the polar bonds are oriented in the opposite direction.
In order to be a polar molecule, carbon dioxide must have both a slightly negative side and a slightly positive side in its molecule. The orientation of the lone pairs of electrons present on each oxygen atom cancels each other, making the molecule non polar.
The laws of superposition and original horizontality are best applied to sedimentary rocks.
Sedimentary rocks are types of rocks that are formed through deposition and subsequent cementation of such material at the Earth's surface and within bodies of water. The law of superposition and original horizontality applies because technically the layers of sediments from which sedimentary rocks are formed were originally deposited horizontally under the gravitational action. Furthermore, since sedimentary rock formation has an undisturbed sequence, then the basic law of geochronolgy (law of superposition) applies since oldest layer is at the bottom while the youngest layer is on top.
