Answer:
D) 13.62 kg/L
Explanation:
This problem can be solved by a simple rule of three.
The problem states that Mercury has a dansy of 30 lbs/L, and asks what is the density in kg/L. We have to convert from lbs to kg.
Each lb has 0.454 kg? How many kg are there in 30 lbs?
So:
1 lb - 0.454kg
30 lb - x kg
This means that mercury's density in kg/L is 13.62, letter D. Letter A is also 13.62, however it is not in the unit asked.

The hurricanes have negative, often devastating effects on the Caribbean and Central America.
Explanation:
Both, the Caribbean an Central America, are located in areas where there is high hurricane activity. These two regions are not well developed, but instead they are developing, and there is large scale poverty, which unfortunately doesn't go well in a combination with the hurricanes. Every year, several hurricanes of varying sizes hit these regions, and the effects are devastating more often than not.
Because the people are poor in general, as well as the countries themselves, the infrastructure is of very bad quality. The systems for warning are either non-existent or not very efficient. When stronger hurricanes hit these two regions suffer badly as most of the infrastructure gets destroyed. The bad organization results in lot of people ending up without any help or with little to no medical assistance. Hundreds of thousands of people every year end up homeless, badly injured, or dead, and part of the reason for that is that the warning systems often don't work properly and don't notify the people on time to take cover in safer grounds.
Some of the countries that often have huge problems because of hurricanes are:
- Haiti
- Dominican Republic
- Belize
- Cuba
