1. Young people think too much. Let's watch the bitcoin documentary
2. Eth, BTC are mainstream virtual currency, can invest! But because the price is expensive, we need strength!
3. F combination= ρ Liquid GV - Mg
4. v= r w= (2p r)/T =2p rn
a= V^2/r = rw^2
F= mV^2/r =m rw 2
T= 2p/w = (2p r)/V
f = (1)/T
a= V^2/r = rw^2
F= mV^2/r =m rw 2
T= 2p/w = (2p r)/V
f = (1)/T
5. AMD's AM2 processor only improves the memory support, not the fundamental improvement from the structure
however, the advantage of core is that it adopts a new processor architecture, which is a fundamental difference
for example: the same top-end processor: it only takes 17 seconds to perform super PI operation (1.04 million bits) with Intel e6800 and 32 seconds to use AMD fx-62. That's the gap!!

6. Tensile strength x = breaking force, but tensile strength depends on the material and its heat treatment and processing state
7. 1c3b, 2 has no correct option
8. Ampere force is constant force, q = I & # 178; RT
the law of conservation of energy for ampere force to be variable force
the law of conservation of energy for ampere force to be variable force
9. Note that the above is LNK
and the following is LGK
makes a transformation, ln10 = 2.303
LGK = LNK / ln10
ln is the natural logarithm with base e, e = 2.71828
LG is the logarithm with base 10

10. The second question: in a period of rotation 2 Wu, of which 8 / 9 Wu in the magnetic field. And in the magnetic field is equivalent to a uniform magnetic field, so when in the magnetic field, there is no difference with the level of uniform motion in the magnetic field, subject to constant ampere force. So we don't use the effective value, and this current can't be called the maximum value, as long as the current is within 8 / 9 of the current. Third question: this equation is the formula for calculating the effective value, that is, I & # 178; RT = I, there are 178; RT t is the period and t is the rotation time in the internal magnetic field. If you are just beginning to learn alternator, take a good look at the textbook. If you are in senior three, you may not understand it at that time, but it doesn't matter. Come on
