Answer:

Birth Rate vs Death Rate

Explanation:

The world has witnessed several wars, diseases, plagues, natural calamities etc which fluctuates the population growth. Humans became more enduring with the increase in survival rate.

Birth rate has significantly increased due to urbanization, modernization, health facilities etc which led to a population boom all over the world. The death rate is relatively lower than birth rate. From 18th Century or last 300 years, the population growth rate doubled from 0.5% to 1%. At the beginning of 21st Century almost 75 million people are added to world population every year.

However, there are other reasons as well that contributed extensively to the population expansion. Third World countries or any developing nation has great illiteracy, poverty and education which results in the growth of population.

The statistics prove that the current 7 billion people shall reach 9 billion mark in 2050.

Some of the major effects of Population growth: Natural Resource Depletion, Environment Degradation, Wars and Unemployment.

There is no single reason for population growth as each and every event has contributed to its expansion.

Which area on the map has the HIGHEST population density in Canada? A) A B) B C) C D) D

Ulleksa [173]

The area in Canada that has the highest population density is the Great Lakes area, located in the south-southeastern part of the country. This region has the largest cities in Canada, and it offers several conditions that makes it the most attractive and suitable for living.

As a country, Canada is very sparsely populated. The country is the second largest in the world, but it has twice smaller population than the United Kingdom for example. The main reason behind this is that the climate is very harsh in most of the country, so very few places offer good or partially good living conditions.

In general, it is the border area with the United States, in the southern part of the country, that has the majority of the population of this country, while the rest is mostly void of population.

The Great Lakes region has by far the biggest population density. The reason for this is that the climate is milder in this region. It is a very well connected region, especially with the major cities in the north and northeastern part of the United States. Multiple economic activities are possible, and the travel and transportation are very easy. This naturally attracted the people to concentrate around this area.

suppose your surface body temperature averages 90^0 F. How much radiant energy in micrometer would be emitted from your body. De

tester [92]

Answer:

$\lambda=9.75\mu m$

Explanation:

Given that,

The temperature of the surface = 90°F = 305.372 K

We need to find the wavelength of maximum energy emission of your body. According to the Wien's law,

$\lambda T=2.98\times 10^{-3}\\\\\lambda=\dfrac{2.98\times 10^{-3}}{T}$

Put all the values,

$\lambda=\dfrac{2.98\times 10^{-3}}{305.372 }\\\\\lambda=9.75\mu m$

So, the required wavelength is equal to $9.75\mu m$ .

Relationships with family, friends, and community far outweigh money or things

ss7ja [257]

Eh, personal opinion. I don't quite get what you're asking here...However I believe that there's some people might believe that money or things are far more valuable than family. This could be because they have a bad relationship with their family,friends, or community.
