Answer:
East to West or longitudianl extent is very great.
Explanation:
The world is divided into 24 time zones. Each of the time zones is set at 15 degrees difference, and they go from east to west. In practice, this means that when someone is taking a longer trip from east to west or the other way around, needs to adjust the clock because of passing through different time zones.
In this case, we have Delhi in India and Norway as a whole (though presumably, the person will land in the southern part of Norway). The difference in time zones between the part of India where Delhi is located and Norway varies as Norway's territory falls into three time zones, so it can be a 3, 4, or 5 hours difference. Now considering that Norway's biggest cities and most of the population are located in the southern third of the country, the chances are that the person in question will have to adjust the clock to 5 hours difference.

Sorry if my answer was incorrect.
These spring<span> tides occur because the Sun and Moon's gravity tug on Earth together. Weaker, or neap, tides happen when the Sun, the Moon, and Earth form an L-shape. Good Luck! So the answer in short is spring tide.</span>
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.
