Computing power of nano

1. Music capacity is not measured by the number of songs. What about 100 MB of music? That 4GB nano can only hold 40 songs
it mainly depends on the size of your music file
the third generation nano is divided into 4GB and 8GB versions

2. 1. SIM card: the size of "standard card" is 25 mm × 15mm is the card used by most mobile phones, which is called big card
2. SIM card: there are two kinds of SIM cards, one is micro SIM, the other is nano SIM, which is smaller than micro sim
1) micro SIM card - Size 12 × 15mm is the size of the chip on the standard card. This kind of card is a small card
2) the nano SIM micro card is the smallest at present, with the size of only 12mm x 9mm. The smaller size is to make room for a certain part of the mobile phone and help the mobile phone develop to a lighter direction.

Micro SIM card and nano SIM card are different in size. Micro SIM card is a little bigger than nano SIM card, which is 3mm longer and 3mm wider. Now, mobile phones are getting thinner and thinner, and even mobile phone cards are getting thinner and thinner. Nano SIM card has a smaller size, which can reserve more space for the mobile phone, make the mobile phone battery bigger, and make the mobile phone motherboard have more space for routing

extended data:

SIM card is mainly used for GSM network, W-CDMA network and TD-SCDMA network, but compatible mole can also be used for idea telephone. Some people call the ruim card and UIM card of CDMA2000 and cdmaOne as SIM card. Although they have similar functions and comply with all the same mechanical and electrical standards and some software standards, the upper application is not necessarily compatible

5. I don't understand your question, but nano
SIM card is as thick as ordinary SIM card. The mobile phone with nano
SIM is no different from the ordinary mobile phone

6. Are you really what you did?
it is really an idea that you have made a modified compound (
) Is it really you who did the end of the empress?

7. (1) In order to be absorbed, no must react with NO2, so blno can be absorbed at least by blno2
and there is 0.2aln2o4 in Al, because the conversion of NO2 and N2O4 is a reversible reaction, so when NO2 is consumed, N2O4 will be transformed into NO2, so 0.2aln2o4 will become 0.4alno2
so (0.8 + 0.4) a ≥ B, a / b ≥ 5 / 6
(2) all the procts are NaNO2, which indicates that NO2 reacts with NaOH together with no, and no resial NO2 reacts with NaOH alone
so N2 = 2B (mol)
② if the proct has both NaNO3 and NaNO2, there is still NO2 left
so N2 = 1.5b + 0.6A (mol), N1 = 0.6a-0.5b (mol)
in reaction 1: n (NaOH) = n (NO2) = 1.2a-b (mol)
in reaction 2: n (NaOH) = 2n (no) = 2B (mol)
so the total amount of NaOH is 1.2A + B (mol)
so C (NaOH) = (1.2A + b) / 0.2 = 6A + 5B (mol / L)

8. 1.
nano
VI
VIM
is just an editor, and nano and VI / VIM are only differences in commands
2.
it is not a problem to edit with one of the three editors, and VI / VIM is recommended

9. The two bottles are made of different materials, so the aneno is heavier. Because it's glass, it's not suitable for small babies. Moreover, the pacifier is not easy to suck, and the milk will leak out. My baby doesn't like to use it very much. Nanobeb is a little better, and it's not heavy. If you put the milk in this bottle, the baby will drink milk, and it won't repel. It's very good.
