What is the meaning of: touching the private parts of a child, vomiting, or carrying the deceased?

Touching the private parts of a child or others means skin-to-skin contact without a barrier. Vomiting is the expulsion of what is in the stomach through the mouth. Carrying a deceased person is lifting and bearing them. Various rulings are associated with these matters, such as the annulment of ablution by touching the front or back private parts, whether vomiting invalidates ablution or breaks the fast, and whether it is recommended to perform ghusl (definition) (ritual bath) after carrying a deceased person. The specific issue should be identified so that it can be answered.
