Go to the after sales service center to repair Huawei mobile pho

1. Hello! The price of Huawei's official customer service center to replace the screen and back cover of glory 9x is about 300 yuan to 400 yuan. The specific price is subject to the official customer service. Some sharing. thank you.

2. ANCC e-cigarette has been started for two weeks. It has smoked five cigarette bombs. It's good to use. No oil leakage has been found for the time being. You can try it out
! Ono hasn't started yet, and doesn't make a comparison for the time being, except that everyone's experience is different. You can also learn more about other brands of e-cigarettes and compare them.

3. The current version of gold coins are generally used to bid for some out of print / rare / card mounted toy pets in the black market
of course, some gold coins will be needed in the upgrade process to learn riding skills, build fortresses, buy heirloom equipment used by trumpets and so on

4. Are you talking about lucky gold coins? Lucky gold coin is used in lucky draw, 100 lucky gold coins can be drawn once. The activity is on the official website of dazzle dance.

5. It depends on the force.

6. Do you mean lucky money?

lucky money can go to the designated website for lucky draw, 100 at a time

7. The work is equal to the proct of the force and the displacement in the direction of the force
when the magnitude and direction of the force change at any time, we need to introce the differential feeling: in the infinitesimal time, the proct of the magnitude of the force and the infinitesimal displacement in the direction of the force is the micro work done by the internal force to the object in this infinitesimal time
"the work done by gravity ring a period of elliptical motion of satellite" needs to be calculated by integral method in mathematical analysis, which is not easy to explain
when a satellite moves in an ellipse, the work done by gravity is zero
if the satellite moves in a circle, then gravity does not work on the satellite.
