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. 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.

5. The security performance of okex digital currency trading platform has always been very satisfactory
6. It's very reliable. I've been trading on okex, and the experience is very good. I didn't encounter any unpleasant problems. Once, I made a mistake in transferring currency. I called the customer service. The customer service attitude was very good, and the currency was found soon. I hope my answer can help you
7. Yes, there are delivery contracts and perpetual contracts.
8. It's definitely worth investing. Bitcoin and lightcoin are the investment procts that go through Niuxiong.
9. Okex is a global digital asset trading platform, which was established in May 2017 and headquartered in Malta. It mainly provides global users with spot and derivative trading services for digital assets such as bitcoin, Leyte and ethereal
