Answer:
1.637687 x 10¹³ m²
Explanation:
Land area of Russia has been given in the question as
A = land area of Russia = 16,376,870 km²
we know that
1 km = 1000 m
hence
A = land area of Russia = 16,376,870 (1000 m)² = 16,376,870,000,000 m²
A = 16,376,870,000,000 m²
To represent the area in exponent form, we shift the decimal place from right to left until we have one decimal place.
So we get
A = 1.637687 x 10¹³ m²
Answer:
Explanation:
Given
saturated air temperature by 
Dew point temperature is given by 
Dew point is defined as the temperature after which air no longer to uphold the water vapor fuse with it and some water vapor may condense to a liquid.
air continues to rise for 1400 m
i.e. change in temperature would be 
Final temperature 
Temperature can be described as an indirect measure of heat energy
So therefore your answer should be letter C
Nuclear energy was not developed. It has existed for as long as time has existed, that is, since the big bang.
The thing that was developed was humans' ability to USE nuclear energy, to do what we want it to do, when we want it to do it.
The reason this was first developed was to bomb the holy beans out of Japan, in order to win World War II.
Today (2020), nine of the world's nations are known to have 14,285 nuclear bombs in storage, for the same general purpose. Seven of these nations are storing 1,170 of these bombs (about 8 percent), and the USA and Russia have all the rest ... 13,035 nuclear bombs.
All nine of these nations promise that they have no plan to use their bombs, they don't want to use them, it would be wrong and terrible to use them, and they will never be the first to use them, but they need to modernize their bombs so that theirs are better than anybody else's bombs, and they need to keep their bombs for as long as anybody else has any, and then maybe a little longer, just in case.
In the years after the ability to bomb the holy beans out of other people was developed, and enough equipment was built to do it 14 thousand times, the ability to use nuclear energy for other purposes was also developed. It's used now to generate electrical energy, and to do several jobs in Medical science.
