questions to wudhu and children

Salam Mufti sahab. I have three questions. Q1. Is it okay to watch children animation cartoons with no vulgarity content or is it haram for any reason. Q2) I heard through someone that if you are in wuzu and you are a female and you go out and your shawl falls from your head showing your hair to “namehram” then your wuzu breaks. Q3) If after doing wuzu u listen to music your wuzu will break? Thank you
