As all community members know I am just a beginner of physics. Mistakes often happens from everyone .Why can't everyone give me a second chance to blot out my mistakes and this is how I can improve my knowledge in physics .So I request community members to withdraw my ban.
You are currently blocked from posting further questions by the automatic question rate limiting, whose different forms I also discuss in this answer. There is nothing any user or moderator on this site can do to ameliorate this ban, it is a fully automatic consequence of your bad question record:
Of your 10 questions, none has a positive score, only one does not have a negative score, only one is not closed, and five are deleted. The question rate limiting is the system telling you to take seriously the feedback you are getting.
On the page that tells you you cannot post further questions you should see a link to this help page, which gives generic tips for how to improve your questions.
