Ladies and gentlemen, I am a little bit of a beginner, and I want to learn more about guitar

Correct upstairs! Between the third and second strings is a note of 5-7 in the third.

Go to my teacher's forum!

Correct upstairs! Between the 3rd and 2nd strings is the note of the 3rd G A, and your 5 7 is relative to the C key!!

In general, the transistor provides current through the DC voltage so that the current falls on the input resistance, so that the current can be amplified by the collector of the triode, so that the output current increases, in this way, the current falls on the resistance of the collector, so that the voltage of the output terminal increases, that is, the output current is controlled by the input current.

Amplify electrical signals.

It can be explained in this way: the triode generally provides current through the DC voltage so that the current falls on the input resistance, so that the current can be amplified by the collector of the triode, so that the output current increases, in this way, the current falls on the resistance of the collector, so that the voltage of the output terminal increases, that is, the output current is controlled by the input current. "This is copied, there are a lot of them on the Internet, you can go to the search office, there is what you want.

Find some simple rolls and follow the book, if you can't find it, just look for it in the book, and if you can't find it, ask the teacher, ask the classmates, ask the parents, ask the neighbors, and the brother.

That's the only way to go, and the so-called review materials are all kinds of questions.

It is most effective to use simplified Chinese titles as a guide to read books slowly.

It was Sen Chang who had already fought quickly.

Love to a certain extent, all problems, not a problem, just depending on how you see each person, (only personal opinion).

The water content of 40 tons of grapes in Xinjiang was 99%.

40 (1-99) tons without water.

After arriving in Nanjing, the water content was measured to be 98%.

The waterless part is unchanged.

So there are tons left after the grapes arrive in Nanjing. Find a pattern!

The numerator does not change The latter term is the denominator of the previous term +1

1.Let x-ton water evaporate, since the mass of other substances other than water remains unchanged, according to the title:

1-98%) 40-x)=40 (1-99%), resulting in: x 20

40-x＝40-20＝20

A: There are 20 tons of grapes left after they arrive in Nanjing

2.Find a pattern!

The first four numbers are equal to 3 in turn, so the next three numbers should be 6 3=

40x(98/99)=

1 The second is a third smaller than the first, the third is a quarter smaller than the second, and the next is a fifth ......

In Xinjiang, the water weight in grapes = 40 * 99% =

After arriving in Nanjing, the water weight in the grapes = 40 * 98% =

Lost water = so, tons of grapes left.

Solution: Because the dry weight of the grapes must be set to Nanjing, there are still x tons.

then 40*99 98 x

solution x

Solution: Because the dry weight of the grapes must be set to Nanjing, there are still x tons.

then 40*99 98 x

Solution of x 2Find a pattern!

The first four numbers are equal to 3 in turn, so the next three numbers should be 6 3=

Water lost = 40 * (99% -98%) =

So, there are tons of grapes left.
