C. For the second one
Answer:
Neither country wanted to engage in a nuclear war that would lead to worldwide destruction.
Explanation:
The US and USSR became arch enemies soon after World War II ended, and that continued to be the case until the USSR seized to exist. The two countries became opponents and developed very bad and tense relations because they had different ideas as to how the world should shape up, but also because both of them wanted to be the only dominant power in the world.
Both countries were heavily armed and the weaponry was constantly icnreasing, with newer and better weapons constantly been created to gain an advantage. Nuclear weapons were abundant at both as well, but they never got used in an open war between them. The reason was simple, if a direct war between them occurred, there would have been worldwide destruction and everyone will lose, so that was kept as the last option in case of an attack by the other. Not to be mistaken though, these two were constantly in war with each other, not just diplomatic, but also military one, just that they used other countries as battlefields where they supported a particular side.
Answer:
log(4)
Explanation: when you subtract logarithms with the same base, you divide them when writing them as one log. 12/3=4 so the answer is log(4)
The Sun is lowest in the sky with less radiation in the Northern Hemisphere during the winter solstice.
Explanation:
The Earth is not static, but instead it is involved in several different motions. One of those motions is the Earth's tilt. Basically, the Earth is tilted with one of its hemispheres (northern or southern) toward the Sun in half of the year, and then in the other half of the year it is tilted with the other hemisphere toward the Sun.
When one of the hemispheres, lets say the Northern Hemisphere, is tilted away from the sky, and that reaches the maximum, it receives the least solar radiation, and the Sun is the lowest on the sky. That occurs on 21 or 22 December, and it is known as the winter solstice. This date represents the start of the winter for the Northern Hemisphere, thus its coldest period of the year.
The four stages on Earth caused by the tilting are:
- spring equinox
- summer solstice
- autumn equinox
- winter solstice
