Like any agricultural product, grain has its own quality characteristics that determine how suitable it is for human use. These parameters are approved by GOST and are evaluated in special laboratories. Grain analysis allows you to determine the quality, nutritional value, cost, safety and scope of a particular batch or variety. Last modified: 2023-12-17 05:12
The Earth's crust, to which mankind has access, reaches a depth of about 20 km. It consists of 95% igneous rocks, 4% metamorphic rocks and 1% sedimentary rocks. Indigenous, rocks that can be used by mankind and for their own purposes are called minerals. And the natural accumulations of these minerals in the earth's crust are mineral deposits, they can be loose and primary. Last modified: 2023-12-17 05:12

The discovery of the neutron was a harbinger of the atomic era of mankind, since in the hands of physicists there was a particle capable, due to the absence of a charge, to penetrate into any, even heavy, nuclei. In the course of experiments on the bombardment of uranium nuclei by neutrons, carried out by the Italian physicist E. Fermi, radioactive isotopes and transuranium elements, neptunium and plutonium, were obtained. Last modified: 2023-12-17 05:12
Karl Braun is a German physicist who lived in the second half of the 19th - first decades of the 20th century and became famous thanks to the invention of the cathode ray tube - kinescope. In some countries, this device is still named after the scientist. Karl Braun specialized in the practical use of electromagnetic waves. In 1909, the scientist was awarded the title of Nobel laureate in physics. Last modified: 2023-12-17 05:12
Stray currents are a kind of directional movement of charged particles that occurs in the earth when the latter is used as a conductor. The main danger of this phenomenon is the development of corrosion of those metal objects that are underground or at least partially in contact with it. Last modified: 2023-12-17 05:12
Probably even a child will tell you what precipitation is. Rain, snow, hail … That is, the moisture that falls from the sky to the ground. However, not everyone can clearly say where this water comes from. It is clear that from the clouds ( although this is also not a firm rule), but where do the clouds come from in the sky? In order to understand the cause and nature of the showers, rains and snowfalls passing over our heads, we need to get an idea of u200bu200bthe exchange of ash-dav-o on planet Earth.

In the 16th century, economic thought in Europe underwent significant changes: an active theoretical search for sources of capitalist we alth began. This turbulent era is rightly considered the period of the primitive accumulation of capital, the period in which the European states began their commercial and political expansion, and so on. At this time, the bourgeoisie is winning back positions not only in politics, but also in the economy. Last modified: 2023-12-17 05:12

In the process of a chemical reaction, what is theoretically planned is not always obtained, at least quantitatively. This is usually due to difficult reaction conditions - non-ideal temperature, insufficient contact with the catalyst, and simply chemical impurity of the reagents. In this case, chemists use the phrase "mass fraction of the yield". Last modified: 2023-12-17 05:12
Kinetic energy is, according to the definition, a value equal to half the mass of a moving body, multiplied by the square of the speed of this body.
