THE INVENTION OF THE AIRCRAFT
Russian inventor Alexander Fedorovich Mozhaisky was the first in the world to conquer the airspace.
From his youth, he dreamed of taking to the air.
In 1877 Mozhaisky made a model aircraft. He demonstrated this model in St. Petersburg. Mozhaisky hoped that he would be allocated ­funds for the construction of the aircraft. But the tsarist government did not support the inventor.
Then he built the plane at his own expense and lifted it into the air. This machine had wings, coraus , motor, tail and landing gear.
The remarkable invention of Mozhaisky received a worthy assessment of descendants.
PHYSICAL DEVICES
An ammeter is used to measure current and a voltmeter. The ammeter is connected to the circuit in series with the section of the circuit in which the current is measured . The voltmeter is connected in parallel to that section of the circuit, at the ends of which the potential difference is measured. To change the resistance of the circuit, you need to include a rheostat in the circuit. The rheostat consists of a wire that is wound around a porcelain cylinder.
The resistance of a conductor can be measured using ammeter and voltmeter. in series with the measured the conductor turns on the ammeter and in parallel to the conductor - the voltmeter.
What is chemistry?
Everything that surrounds us - animate and inanimate nature and everything that is created by human hands - consists of substances. Iron, aluminum, copper, water, sugar, oxygen, carbon dioxide, starch, proteins are all substances. Now more than three million substances are known, but their list is constantly updated. Substances may be somewhat similar to each other, but each has its own characteristics, its own properties. One of the tasks of chemistry is to describe substances. For example, we describe table salt as follows: a colorless substance (when crushed it is white), salty in taste, brittle, soluble in water, does not change when heated, etc. When describing substances, their properties that can be measured are also indicated, for example, melting and boiling points, density, etc.
Chemistry is the science of substances and their transformations into each other. The discovery of the laws of transformation of some substances into others makes it possible to foresee and explain such transformations, control them and apply them to produce the necessary products. The transformation of substances is always accompanied by physical phenomena: the release or absorption of heat, the emission of light, a change in their state.
The importance of chemistry in the life of society is also great; knowledge of it is becoming increasingly necessary for creative work in any field.
