A Lady Pulling out her Hair
Question :

Is there any kaffarah for a lady to pull out her hair in grief and mourning?

Answer :

It is prohibited for the woman to do so. The kaffarah for doing so is either giving ten needy people 900 grams of food each - staple food items such as dates, flour and rice - or clothing them; if neither of these are possible, then she should fast for three consecutive days.

Tearing One's Clothes
Question :

Is it prohibited to tear one’s clothes? And is there any kaffarah if one does it?

Answer :

It is prohibited for the man to tear his clothes in mourning over his child or wife, and the kaffarah for doing so is giving ten needy people 900 grams of food each - staple food items such as dates, flour and rice - or clothing them; if neither of these are possible, then he should fast for three consecutive days.
Tearing the clothes for other than that is not prohibited, like a man tearing his clothes in mourning for his brother, or a woman tearing her clothes in mourning her husband, son, or brother.

Kaffarah
Question : If a woman was pregnant for 10-15 days and she had an abortion, then will she be required to pay kaffarah, and how much?
Answer : It is obligatory to pay the kaffarah for committing abortion. It is the same as the kaffarah of deliberately taking the life of an adult, which is freeing a slave, feeding sixty needy believers, and fasting for two consecutive months.
