Page no 5.30,Question no 5 and 10

Dear Student!
Your question makes no sense without the name of the book, the subject and the class in which you are studying. Also, only giving question numbers may not help you fetch answers, because we may not have the book to look into the question. So, you need to mention full question with options, if any, to get the answers. Kindly reframe the question and ask again.
Hope you understand.
Good luck!
