Two conditions in which abortion is not allowed.

Abortion law permits, prohibits, restricts, or otherwise regulates the availability of abortion. Abortion has been a controversial subject in many societies throughout history on religious, moral, ethical, practical, and political grounds. It has been banned frequently and otherwise limited by law. However, abortions continue to be common in many areas, even where they are illegal. According to the World Health Organization (WHO), abortion rates are similar in countries where the procedure is legal and in countries where it is not,[1] due to unavailability of modern contraceptives in areas where abortion is illegal.[2]

Also according to the WHO, the number of abortions worldwide is declining due to increased access to contraception.[1] Almost two-thirds of the world's women currently reside in countries where abortion may be obtained on request for a broad range of social, economic, or personal reasons. Abortion laws vary widely by country. A few countries have banned abortions entirely.

Btw, I got this info from google and gathered it to make this, so if this is wrong then sorry.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
