Hi, welcome to the wiki. I recognised the text you submitted to your user page as a copy-paste from Wikipedia's Delta-v page. Technically, your upload was a copyright violation, and not permitted. Rather than just removing the content, I have added a suitable notice to put it in compliance with the CC BY-SA license. Please familiarise yourself with Wikipedia's licensing terms at WP:REUSE.
In general, most free content cannot be just reused without taking steps to comply with license terms; it may be free, but is still fully protected by copyright law, owned by the original creator(s), and can only be distributed under the terms of the license(s) attached to it. It is your legal responsibility to ensure that you have a license to submit any content that you did not create yourself, and to comply with the terms of that license.
The notice I have added solves the copyright violation, and you are not in any trouble. It is just important that you understand that there was a problem. Thanks.
