The Tropic of Cancer passes through eight states in India whereas the Standard Meridian passes through five states in India.
The Tropic of Cancer is the northernmost circle in the latitude of the earth. The Standard Meridian is the longtitude that helps describe the time in a country.
- The Tropic of Cancer is among the most prominent latitude circles that divide the earth in various levels.
- The Tropic of Cancer passes through India.
- The line specifically passes through eight Indian states.
- These states are: West Bengal, Tripura, Mizoram, Jharkhand, Madhya Pradesh, Chhattisgarh, Gujarat, and Rajasthan.
- The Standard Meridian is a longitudinal line that runs across the Indian subcontinent.
- This line describes the time in a country.
- In India it passes through five states.
- The states are: Uttar Pradesh, Chhattisgarh, Madhya Pradesh, Andhra Pradesh, and Orissa.
Therefore, the Tropic of Cancer passes through eight states in India whereas the Standard Meridian passes through five states in India.

The population density of Europe, as a whole, is 143 people per square mile. This makes Europe the second most densely populated continent in the world, with the first place being occupied bu Asia, so we can say that Europe is a densely populated continent as a whole.
It has to be taken in notice that Europe is a continent that has an aging population, the fertility rate is very low, and the life expectancy is high. Interestingly enough, even though there's only three countries in the whole continent that have a positive fertility rate, the population of the continent is still growing, slowly, by 0.3% annually, but it is growing. The growth is mainly because of the migrants, mainly from the Middle East and Africa, and apart from increasing the number of the population with their entry, they also tend to have a high fertility rate.
Set this up as
10 = 40 (1/2)t/28
and solve for t in years.
10/40 = (1/2)t/28
log(0.25) = (t/28) log(0.5)
t = 28 log(0.25) / log(0.5) years = 56 years
Test the answer:
56 years = 2(28 years) = 2 half-lives, so the remaining amount should be 1/2 of 1/2 of the initial amount, i.e. 1/4 of the initial amount, and 10 mg = 1/4 of 40 mg.
