Okex notes
Publish: 2021-04-30 20:52:10
1. No, other exchanges can trade Leyte, but okex is better for contract trading.
2. The price of Leyte currency soared 10 points today. Is it OK.
3. Yes, Leyte currency, ether currency is the mainstream currency. Of course, okex has it.
4. 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,

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.
6. Certainly not. Now virtual currency is basically a kind of fraud, if the old horse in, it is not such a kind of operation.

8. 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.
9. Blockchain is very hot. Every day, a lot of money enters the blockchain, but also flows out. It is dynamic.
10. Don't believe in this kind of Laite currency. It's illegal to use this kind of virtual currency in China.
