That friend helped me think about 5, that friend helped me think about it

First of all, you have to be 100% sure that she doesn't love you! If she doesn't love you, then you leave, don't play any emotional games with her, in love, the one who loses is always the one who loves in his heart!

It's easy to leave her, but it's not so easy to forget, and the stupidest and most effective way to do that is to let time dilute everything! It definitely works! It's just a matter of time.

Give up, give up, give up, give up! When it is broken, it is broken! It's chaos if it's constant! Don't waste your youth and time! Why hang a tree!

You calculate m, and the problem is very simple. The back tells you 7o4=41, and then brings it to the known condition given to you in the front, calculates m, and then according to the following question, brings it in, and the answer comes out.

Write out that the ratio is that the ratio is (3:2) and (6:4) is composed of a ratio (3:2 = 6:4).

From the 16 factors, 4 factors are selected and they are composed in a ratio of (1:2 = 4:8).

I write my own essays well, and I don't write them without 500 points.

Tomorrow, then write the hottest environmental protection at the moment, tomorrow you get up, you find that the earth has been bad, scarred, are human over-exploitation and use of energy and the like, and then the earth is going to perish, you call on everyone to protect the environment and low-carbon, and finally find out that it is a dream.

Homemade energy-saving night lights.

1. Material:

1) 22 high-brightness white light-emitting diodes;

2) A discarded watch case and a whetstone;

3) One universal plug-in board and one switch;

4) Two battery boxes, one double-ended small plug-in;

5) 51, 1 8W resistor, short line, wire.

2. Tools:

1) One 25-watt soldering iron;

2) One pair of needle-nose pliers, one pair of off-the-nose pliers, and one pair of tweezers.

3. Creativity:

There are countless lights in the house, and the living room, bedroom, and dining room are all combination lights. It's good-looking, but there are too many light bulbs, too much electricity, and the two bad bulbs in three days, either this one is not lit, or that one is not bright, and it is not beautiful. If in the bedroom is not required strong brightness.

Now that there are high-brightness LEDs, two or three No. 5 batteries will do the trick, so why not try them.

4. Production process:

Six diodes are connected in parallel, with the positive and negative electrodes connected together, and placed inside the case. However, the diodes are too high and the watch case is too thin to fit, so the diodes were carefully observed and found that the upper part could be removed without affecting the quality. Sharpen off the parts one by one with a whetstone, connect them into a ring, and place them inside the case.

Lead the wire out, find a waste double-ended small plug-in, and connect it to the No. 5 battery box after it is drawn. But the brightness is only equivalent to a small flashlight.

Improvement method: use several more light-emitting diodes and add two batteries. I drew a circuit diagram first.

The 16 diodes are placed in four groups, plugged into the universal soldering board, connected in parallel with a short route, and then connected to the two battery boxes with a 51 resistor limit. Considering that the voltage of the two batteries is insufficient and the brightness is not enough, use three batteries, stack the two battery boxes up and down, and weld the diodes and circuits together according to the circuit diagram.

I turned off the bedroom lights and turned on my energy-saving lamp, which was so bright. That's a lot of power saving! And it's not easy to break. The cost is still very low, 8 cents per diode, a total of more than 20 yuan. The combination lamp at home costs more than 200 yuan.

Figure 2 shows that A is opposite to 4, 2 is opposite to B, and C is opposite to 1.

As can be seen from Figure 3, 1 and 6 are opposite, 3 and 4 are opposite, then it can be inferred that 2 and 5 must be relative, and analogous to the results of Figure 2 and Figure 3, we can see that A=3, B=5, and C=6

This is very simple, and you can do it after studying in junior high school.

It is equal to minus sixteen minus one plus eight and one eighth is equal to minus eight and seven eighths.
