WHAT IS AN ELECTRON?
What is an electron?
It is a very small, indivisible, fundamental particle – a major constituent of all matter.
All electrons appear to be identical and to have properties that do not change with time.
Two essential characteristics of the electron are its mass and its charge.
Qualitatively, an electron is a piece of matter that has weight and is affected by gravity.
Just as the mass of any object is defined, the mass of the electron can be defined by applying a force and measuring the resulting rate of change in the velocity of the electron, that is, the rapidity with which its velocity changes.
This rate of change is called acceleration, and the electron mass is then defined as the ratio of the applied force to the resulting acceleration.
The mass of the electron is found to be about 9.
11 10 - 28 grams.
Not only the electron but all matter appears to have positive mass, which is equivalent to saying that a force applied to any abject results in acceleration in the same direction as the force.
How does the other aspect, the charge of the electron, arise?
All electrons have an electric charge, and the amount of charge, like the mass, is identical for all electrons.
No one has ever succeeded in isolating an amount of charge smaller than that of the electron.
The sign of the charge of the electron is conventionally defined as negative ; the electron thus represents the fundamental unit of a negative charge.

If all the trees were one tree, What a great tree that would be!
And if all the axes were one axe, What a great axe that would be!
And if all the men were one man, What a great man that would be!
And if the great man took the great axe, And cut down the great tree, And let it fall into the great sea, What a splish - splash that would be!

Переведите пожалуйста текст буду очень благодарен : The transformer A transformer cannot be called a machine for it has no moving parts.
We know the transformer to be an apparatus designed for changing voltages and currents by means of magnetic induction.
A two - winding transformer is consist of two coils so arranged that the magnetic lines of force of one coil pass through the other.
Transformers is generally used only with alternating current.
The alternating current in one coil induces an e.
M. f.
In the other one because of the alternations in the value of the current in the first coil.
In order to strengthen the magnetic field passing through the coils of a transformer, a closed core of iron is generally used.
The iron provides a good path for the magnetic lines of force and nearly all the lines of force from one coil pass through the other.
An ideal transformer has no load losses.
It means that all the lines of force of one coil pass through the other, and vice versa.
However, the ordinary transformer is supposed to have no load losses.
The coil on which the current is impressed on the input side of the transformer is called the primary, while the one from which the induced current is obtained on the output side is called the secondary.
In case the secondary has more turns than the primary, the output voltage is larger than the input voltage and the transformer is called a step – up when transformer.
The secondary has fewer turns than the primary the transformer is called a step - down transformer.
If the same number of magnetic lines of force pass through two - coils, the ration of the e.
M. f.
Induced in the two coils is proportional to the ratio of the number of turns in the two coils.
In the transformer this means that the e.
M. f.
In the secondary is to e.
M. f.
In the primary as the number of turns in the secondary is to the number of turns the primary.

Напишите как читается :
Only when all the rivers
have run dry
And all the fish in the sea have died
Only when all the rainforests
have been burnt down
And there is no food for animals
Only when all the blue skies
have been filled with smoke
And the cities of the world have choked
Will the white man understand that
It’s too late to save the earth.

Что такое электрон ?
Это очень маленькая , неделимая частица - основная составляющая всей материи .
Все электроны оказываются идентичными и обладают свойствами , которые не изменяются со временем.
Две существенные характеристики электрона - его масса и заряд.
Качественно электрон - кусок материи, которая имеет вес и подвержена влиянию силы тяжести.
Так же, как определяется масса любого объекта, массу электрона можно определить, применяя силу и измеряя полученную скорость изменения скорости электрона, т.
Е. Скорость, с которой его скорость изменяется.
Эта скорость изменения называется ускорением, а затем масса электрона определяется как отношение приложенной силы к полученному ускорению.
Масса электрона составляет около 9, 11 или 10 - 28 грамм.
Полагают, что не только электрон, но и вся материя имеют положительную массу, что эквивалентно утверждению, что сила, приложенная к любому презрению, приводит к ускорению в том же направлении, что и сила.
Как возникает другой аспект, заряд электрона?
Все электроны имеют электрический заряд, и величина заряда, как и масса, одинакова для всех электронов.
Никто никогда не удавалось выделить количество заряда меньше, чем электрон.
Знак заряда электрона условно определяется как отрицательный ; Таким образом, электрон представляет собой основную единицу отрицательного заряда.
