Okex is much cheaper

1. Different prices are caused by different markets. That's why there is a brick instry. You can refer to the difference between Chinese currency and fire currency to move bricks. In addition, as the No.1 platform for inputting mainstream currencies such as bitcoin and Ethereum, you can go to see if they meet your operation requirements.

2. The price of Leyte currency soared 10 points today. Is it OK.

3. Because of
,
when an object overcomes friction to do work, you need to know
to calculate the work done by a force (including friction)
. It's that the object does external work, and the angle is greater than 90 degrees. This is not the case.
the state of motion has nothing to do with overcoming friction. We can also say that the object is doing work against friction. There are different situations: 1. Putting pressure on the gas is just a change of opinion. Work done to overcome friction is friction multiplied by distance. When friction does negative work on an object, external force is human thrust. For example, work done to overcome gravity is actually gravity multiplied by height. Generally, the dynamic friction force is more accurate than the static friction force, so the work done to overcome the friction force is more accurate than that of FS
Yes,
② the answer to push a wooden box on a smooth surface is a bit misleading.
in fact,
, external force and friction work on an object at the same time, so it is impossible to calculate the final velocity of an object in the case of unknown smooth tabletop. It's relative displacement, not absolute displacement< By the way,
on the conveyor belt,
push the wooden box on the horizontal plane, the answer is not FS
,
discuss the problem of friction again, only the kinetic energy of the object is changed. Of course, there is a difference.
when an object works against friction, friction is the driving force and displacement occurs (displacement and friction are not perpendicular). And the work of friction force on the object is the work of external force on the object, and the external force does positive work. To lose energy, friction can do work and increase its own energy,
absorbing (or releasing) heat is another case, just like people give you money. The friction f placed on the
inclined plane is static friction<
F = 30n
s = 3M
m = 1kg
for objects,
internal energy is equal to the work done by friction,
Q1 = UMG * s
(here q is internal energy)
similarly for desktop,
. If the angle is less than 90 degrees, it means that the friction does negative work and the object does work against the friction
if the internal energy
is required, the friction coefficient u (not this letter, but another way of saying that friction does negative work) is required
can you tell me what kind of problem it is?. Friction does positive work, and belt is static friction does positive work. Friction does positive work. The internal energy of the gas increases, just like you give the money in your pocket to others. It is a kind of situation that an object overcomes friction to do work. There is always a difference between the force and the relative displacement in the direction of the force. That is, the object is subject to friction (which can be a component force), and the friction is resistance,

4. 1-75: copper ore (smelting experience, can dig 1-4 times) associated with poor quality stone, malachite
it's easy to dig in the birthplace, plus smelting experience, 50 + mining experience can be easily achieved

75-125: tin ore (smelting experience, can dig 1-4 times) 50 skill requirements, associated with tiger eye stone, shadow stone, rough stone
tin mine is also a very popular mineral. It is recommended by tribes to go to barren land / coniferous forest; The League recommends Chiji mountain

silver ore (smelting experience, can dig 1-4 times) 75 skill requirements, associated with tiger eye stone, rough stone
silver mine is the first rare mine we can encounter. Copper mine generates silver. That is to say, after a certain copper mine is collected, there is a certain chance to refresh silver mine next time. Of course, silver mine is also used as an independent refresh in advanced map. The tribe here recommends barren land / thousand needle stone forest; The League recommends Chiji mountain

125-175: iron ore (can be excavated 1-4 times) 125 skill requirements, accompanied by heavy stones and topaz
there are many places, but none of them is relatively distributed. However, I still suggest to go to the shining plain at the edge of the thousand needle Stone Forest - & gt; Tanalis, there's a lot of data going back and forth on this line

gold mine (smelting experience, 1-4 times of excavation) 155 skill requirements, accompanied by heavy stones and topaz
this is the second kind of rare ore that we can meet, and the last kind of ore with experience in smelting. Iron generates gold. Similarly, after the iron ore is collected, the next refresh will have a certain chance to refresh gold. Of course, the advanced map will refresh, but it is rare

175-245 mitag mine (can be excavated 1-4 times) 175 skill requirements, accompanied by solid stone, turquoise and ruby
two places are recommended for large-scale collection:
1. Barren land, as shown in Figure 1, will brush three secret silver in area a and two secret silver in area B. the refresh of these two places is very fast, and a circle of maps outside can't be finished, so areas a and B will refresh
2. If you think that there are too many people in the barren land, I recommend a small place, the altrank mountains, as shown in Figure 2. In the cave of area a, 2-3 secret silver will be refreshed each time, and in the refresh point outside, 3 mines will be brushed each time. This place has few people, and the map is small, and the refresh is relatively fast, which is suitable for a large number of collection

300-330, mainly to dig the magic iron ore

first of all, dig many magic iron ores distributed on Hellfire Peninsula clockwise

If Hellfire Peninsula is full of miners, go to ZANZA swamp

330-355, mainly for Moxian iron mine and Jiangang iron mine<

going to nagland grassland and digging hard steel ore can not only improve skills, but also sell ore at a good price

at the same time of digging hard steel ore, magic iron ore can also be collected together, even in the later stage, the consumption of magic iron ingot is still considerable

355-375, mainly for Moxian iron mine and Jiangang iron mine

yingyue gorge is the best choice for mining Jiangang mine

if the level is not enough, you can also choose to practice mining skills in the tiroka forest

don't forget to continue to search for magic iron ore while digging hard steel ore in yingyue canyon

if you are in a PvP server, it is quite safe to go to the taroka forest to dig magic iron ore and improve mining skills<

5. It's hard to say that bitcoin is the first digital currency based on blockchain in the world, which is invested by investors all over the world. For the time being, bitcoin is the largest investor. Other currencies have less influence than bitcoin, and their audience is not wide enough.

7. When users conct transactions (legal currency transactions, currency transactions, contract transactions, etc.), they can only trade the currency in each transaction account. If they want to sell the currency in the wallet, they need to transfer the currency in the wallet to the corresponding transaction account, and then they can carry out various transactions.
