Can small program recharge virtual currency
secondly, confirm your question, you mean whether you can convert the game currency back to RMB, because if it exists in the form of RMB, it is called withdrawal, and it is impossible to withdraw if it is a virtual currency
back to your question, the reason why the app can't withdraw cash is that if the virtual currency inside can be reversed into RMB, it will impact the real monetary system, which is risky
I remember many online games in which the game currency purchased by RMB is used for gambling, For example, if the game currency (happy beans) can be reverse converted into RMB, what's the difference between this and changing chips in casinos, so in my impression, one of the keys for law enforcement agencies to determine whether it is gambling is whether the game currency can be reverse converted into RMB
hope to adopt, thank you!
you can buy
you recharge to Alipay, he buys you the selected application
thank you for recharging the network privileges that are difficult and need many
Oh, I said the recharge should be based on the actual situation.
see how the application of your application is
if it's just information display, you can try to select information query and quotation / price comparison.
this is consistent with the principle of measuring acceleration with dot timer
the problem is not difficult, because the glass plate starts to move from a static state, and the time interval through OA, AB and BC is equal, that is, it is half a vibration period, and OA: OB: OC = 1:2:4. Moreover, after careful analysis of the figure, it is not difficult to get the result of the glass plate moving uniformly and linearly Note: OA: OB: OC = 1:2:4 is only the inevitable result of uniform acceleration linear motion, so it can not be concluded that the glass plate makes uniform acceleration linear motion. So we have to analyze the figure carefully, and finally judge that the glass plate is moving in a straight line with uniform acceleration.)
the lengths of OA, OB and OC have been known, and the time has also been known, so the acceleration can be calculated. Then Newton's second law, force F can be obtained. Do it yourself< It seems that you haven't done "the physical experiment of measuring object acceleration with clock"!
Simple harmonic motion equation:
{rrrrrrr}
extended data:
the circular frequency of simple harmonic motion is determined by the mechanical properties of the system. For example, the circular frequency formula of spring oscillator is as follows, where K and M represent the stiffness and mass of spring oscillator respectively. For a given spring oscillator, the circular frequency is only related to its own stiffness and mass, It is determined by its own nature<
simple harmonic vibration is the simplest and most basic vibration. Any complex vibration can be regarded as the synthesis of several simple harmonic motions. The basic laws of vibration and wave are the basis of acoustics, seismology, electrotechnics, electronics and optics
rad / s and the radius of the circle be r
then, if the center of the circle is taken as the equilibrium position, the displacement of the object at t time is
s = rsin (at)
velocity v = S & # 39= Arcos (at)
acceleration a = V & # 39=- A ^ 2rsin (at) = - A ^ 2 * s
therefore, there is a relationship between the acceleration and displacement of the object a = KX
that is, the object makes a simple harmonic motion
