1. It must be. The trading volume of okex is the largest in the world, and the number of users is also the largest in the world. The number one of double materials is okex.
2. 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,

3. That is the driving force of the national interests of the United States and the foundation of American hegemony. The forces that have touched the foundation of the US dollar are the targets that all parties in the us want to eradicate
first, the biggest threat to the US dollar is the euro, so there are always wars or crises around Europe. Europeans themselves know the role of the United States and have been suppressing the euro area, making it impossible for the euro to reap like the US dollar
Second, the Japanese yen is completely spoiled by the United States. The United States can adjust the exchange rate of the Japanese yen to whatever it wants. Moreover, as long as the Japanese prime minister who is not pro american has always stepped down for about a year, senior officials who are not pro american often die strangely
now and in the future, the United States will use its military and its strength in politics, economy, science and technology to suppress those who challenge the hegemony of the US dollar. A string of numbers can be exchanged for countless resources, which is the US dollar hegemony.

4. bitcoin is indeed more than ordinary people used to understand money. Let's say that if blockchain is the Internet, bitcoin is like e-mail. Bitcoin is an application of blockchain technology, and the future development prospect of blockchain is very broad, not limited to digital currency. Just as the Internet is booming, its application scope is not just e-mail. But now people are still familiar with bitcoin. If you want to know more about it, you can learn about it in okex, which is the world's leading exchange platform.
5. To put it simply, you open short or long eth / USD on 58coin exchange, then buy and sell eth in the spot leverage market to hedge. However, this can only be fully hedged when the BTC / USD price remains unchanged. Once the BTC price changes (it changes all the time), then the hedging will not be established
for example: suppose that your actual profit in a transaction is 1 BTC. At that time, BTC's dollar price was $8000. Suppose that within a week after the transaction, BTC's dollar price depreciates from $8000 to $7000, then the profit in dollar terms will also decrease from $8000 to $7000. On the other hand, if the dollar price of BTC rises from $8000 to $9000, then your profit will also rise from $8000 to $9000
therefore, once you make a profit, you need to convert the BTC into US dollars and lock the profit into a fixed amount of US dollars (in this case, US $8000).

6. Of course, the unique contract transaction on okex is not available in fire coin and coin. It's very easy to use. I use okex.

Apple needs a Hong Kong ID, and the download method is the same. I remember that there is a Hong Kong ID in the official microblog of okex. You can find it
9. There are many ways to buy bitcoin in the okex app. You can buy bitcoin in the legal currency transaction. Okex supports fast transaction, which can arrive in one minute. You can also buy bitcoin in the currency transaction. The advantage is that you can add a variety of digital currencies at the same time, and trade at real-time price, depending on your personal needs.
10. Domestic stop moving abroad, the transaction is still continuing, EBIT can still be used
