Answer:
We know that sin(x) = cos(90°-x). In that sense, we know that:
sin(25°) = cos(90°-25°) = cos(65°)
If you put both values in a calculator, we get that:
sin(25°) = 0.4226
cos(65°) = 0.4226
Therefore: Sin 25° = Cos 65°
Answer:
Many oil rich nations in the middle east must import fresh water this is due to the reason that all the natural resources are not present in a particular region. Each region as different degree of natural resources . Hence places with oil mines have spares water resources and hence need to import water instead of oil.
The sequence is in the following order;
- The sun radiated sunlight (visible) photons
- Photons from the sun strike the earth and become infrared photons
- Earth radiates infrared photons into the atmosphere
- CO2 in the atmosphere absorb infrared photons
- CO2 in the atmosphere emit infrared photons back towards earth
Description The Fermi paradox, named after Italian-American physicist Enrico Fermi, is the apparent contradiction between the lack of evidence for extraterrestrial civilizations and various high estimates for their probability. Michael H. Hart formalized the basic points of the argument in a 1975 paper.
