The scale factor is defined by the following expression:
(1)
Where:
- Scale factor.
- Scale distance, in centimetres.
- Real distance, in centimetres.
1) If we know that
,
,
and
, then the actual distances in metres are:












2) If we know that
,
,
and
, then the actual distance in kilometres is:












This is due to the presence of the sea and the accompanying winds. Both of these factors help coastal communities retain more heat during the winters and are also able to cool off easier in the summers, thus having cooler summers and milder winters.

Hi !
Here is your answer !
One of the first things the IPCC concluded is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, buildings, factories, and power plants. The gas responsible for the most warming is carbon dioxide, or CO2.

Canada ranks 38th by population, comprising about 0.5% of the world's total,[2] with over 37 million Canadians as of 2019.[3] Despite being the fourth-largest country by land area (second-largest by total area), the vast majority of the country is sparsely inhabited, with most of its population south of the 55th parallel north and more than half of Canadians live in just two provinces: Ontario and Quebec. Though Canada's population density is low, many regions in the south such as the Quebec City–Windsor Corridor, have population densities higher than several European countries. Canada's largest population centres are Toronto, Montreal, Vancouver, Calgary, Edmonton and Ottawa with those six being the only ones with more than one million people. The large size of Canada's north which is not arable, and thus cannot support large human populations, significantly lowers the country's carrying capacity. Therefore, the population density of the habitable land in Canada can be modest to high depending on the region.
The historical growth of Canada's population is complex and has been influenced in many different ways, such as indigenous populations, expansion of territory, and human migration. Being a new world country, immigration has been, and remains, the most important factor in Canada's population growth.[4] The 2016 Canadian census counted a total population of 35,151,728, an increase of around 5.0 percent over the 2011 figure.[5][6] Between 1990 and 2008, the population increased by 5.6 million, equivalent to 20.4 percent overall growth.[7]
