    You should go to the local place where there are many electronic products and ask, office office software should be fine, wired network socket does not seem to be available. But the MP5 of the Android system takes a long time to boot up, and it automatically self-tests once when it is turned on! Generally not particularly need or don't buy Android!

    The concept of MP4 is nothing more than two concepts, one refers to the ** format after ***, from a technical level, MP4 uses MPEG-2 AAC technology, which is also referred to as A2B or AAC technology. It is characterized by a more perfect sound quality and a larger compression ratio (15:1-20:).

    1)。It adds features such as perfect reproduction of stereo sound, bitstream effect sound scanning, multi-** control, noise reduction, etc., so that the sound quality of the CD can still be perfectly reproduced after audio compression.

    The other refers to a portable device that supports MPEG-4, a **format**, let's first take a look at what is also called MPEG-4) is a kind of MPEG format, which is a compression method for live images. With this compression, it is possible to provide high image quality with smaller files and is one of the most popular file formats (especially on the web). The advantage of this format is that it not only covers the low frequency band, but also moves towards the high frequency band.

    MP4 has attracted a lot of attention since the day it was proposed, and the most popular compression methods for MP4 are DivX and XVID. After the MP4 technology processed by DIVX or XVID, the image and audio quality have not decreased much, but the volume has been reduced to a fraction of the original, and it is easy to use two ordinary CD-ROMs with a capacity of 650MB to save the generated files. A single disc can hold a hundred and a few minutes of a movie, and the picture quality at this time is significantly better than that of VCD.

    MP4,If you have to say,It's just a compression standard,It's like VCD is based on MP2,***It seems that only audio can be compressed,MP4 audio,** can be compressed,Usually some on the computer。

    It's called mp5 is not a white or a profiteer.,Support a few more format copycat manufacturers in order to attract customers to call mp5,In fact, large domestic manufacturers are not called mp5 only mp4,Foreign ones are called pmp。 Only patriots and Newman led the cottage is called mp5,Generally poor quality,Poor performance,Known only by fooling people,The building is mainly unbelieving.,I've seen mp9 in the cottage market.。

Before the line is broken, the three objects move together at V1 speed, according to the conservation of momentum, there is MV0=3MV1, so there is V1 (1 3)V0, when the line is broken, the spring has impulse at both ends, so it can be regarded as the total momentum is still unchanged, let C leave the spring, the speed of AB is V2, the direction is to the right, then there are 2MV2 + MV0 MV0, V2 0, that is, when C leaves the spring, A and B are stationary. Before the collision, the kinetic energy of the system e0=(1 2)m(v0) 2;The kinetic energy of the system before the line is broken is e1 (1 2)*3m*(v1) 2=(1 6)m(v0) 2;When c leaves the spring, the kinetic energy of the system is e2 (1 2)*2m*(v2) 2+(1 2)*m*(v0) 2 (1 2)*m*(v0) 2. We can see that before the line is broken after the collision, the total kinetic energy of the system is reduced to e1 = (1 6) m (v0) 2, and after the broken wire c leaves the spring, the kinetic energy e e2 = (1 2) m (v0) 2, and the system kinetic energy returns to the initial kinetic energy, indicating that after the spring ** is broken, the kinetic energy is added to the system, and the potential energy of the spring is e, then there is e e2 e1 (1 2) m(v0) 2 (1 6) m(v0) 2=(1 3) m(v0) 2. >>>More
