Answer:
The electromagnetic radiation per-unit- area increase by 42.65 times.
Explanation:
The radiation per-unit- area (P) is directly proportional to the fourth power of the temperature. Thus,
P ∝ T⁴
For, when the temperature is raised from T₀ to T₁ , the radiation per-unit- area is related to as:
T₀ = 900 K
T₁ = 2300 K
So,
<u>P₁ = 42.65 P₀</u>
<u>The electromagnetic radiation per-unit- area increase by 42.65 times.</u>
Answer:
Transitional Stage
Explanation:
Declining death rates due to increased food production and improved medical care while birth rates remain high is characteristic of the TRANSITIONAL stage of the demographic transition.
The human population continues to increase at this point because of rising birth rates and declining death rates. The death rates are declining as there are changes in the economy and social conditions as the country transforms into an developed society.
The theory of demographic change is a theoretical explanation of rising mortality, fertility, and rates of growth as populations shift from one demographic system to another.
Answer:
Because London is a big place, and you need to be rich to live in certain districts. Plus you could be talking to someone who lives not that far away, so maybe you will have something in common with that Londoner. If in reply to their question you answer Knightsbridge, South Kensington, Chelsea, Belgravia, Mayfair, St. John's Wood, Primrose Hill, St. James, Holland Park, Regents Park, or Notting Hill; you are telling people you are rich. You need to be rich to live in districts like those, just like the New Yorker who lives in Upper East Side. If your answer to their question is Tottenham, Wood Green, East Ham, Stratford, Dagenham, Barking, Canning Town, Hounslow, or Woolwich; you are telling people you are poor. Very few rich New Yorkers opt to live in the South Bronx. Likewise people will take it to mean you are a regular everyday person struggling to make ends meet, if you live in one of London's poorest districts.
Similarly if you answer Barnes, Kew, Camden Town, Clapham, Hampstead, Highgate, Bayswater, Hammersmith, or Swiss Cottage you are likely to be in a very good job if not a millionaire. If you own a house in any of those districts you are going to be worth close to or more than £1m once the mortgage has been paid off.
