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.
Answer:
The Quebec-City-Windsor Corridor
Explanation:
The population density of Canada is 4 people/km².
The most densely-populated urban areas are Vancouver and Montreal (4800/km²).
The most densely populated region of Canada (80/km²) is the Quebec-City-Windsor Corridor. It contains almost half the population of Canada.
There are two main reasons for this.
(a) Climate
The region is entirely below the 47th parallel, so the summers are warm, the winters are not harsh, and the area is suitable for agriculture.
(b) Location
The corridor is close to the border with the United States and carries the bulk of Canada's trade with them. It makes sense for people to live as close to the US border as possible.
