Answer 1

Answer:

**How do oral contraceptive help in avoiding pregnancies?

-The birth control pill works by stopping sperm from joining with an egg (which is called fertilization). ... No ovulation means there's no egg hanging around for sperm to fertilize, so pregnancy can't happen. The pill's hormones also thicken the mucus on the cervix.

**What is sex selective abortion ? How does it affect a healthy society.

-Sex-selective abortion is the practice of terminating a pregnancy based upon the predicted sex of the infant. The selective abortion of female fetuses is most common where male children are valued over female children, especially in parts of East Asia and South Asia (particularly in countries such as People's Republic of China, India and Pakistan), North America, as well as in the Caucasus, and Western Balkans.

it disbalance the gender gap & hence   a great lose  to society

**State Joule's law of heating.

When current flows through an electric circuit, the collision between the electrons and atoms of wire causes heat to be generated. How much heat is generated during current flowing through a wire and on what conditions and parameters do the heat generation depend? James Prescott Joule an English physicist, coined a formula which explains this phenomenon accurately. This is known as Joule’s law.
