Answer:
The F u k u s h i m a nuclear accident gave ''wind in the back'' to the opponents of the production of nuclear energy because of the dangers from it.
Explanation:
Nuclear energy is produced via nuclear reactors. They are very expensive to be constructed and maintained, but the expenses are balanced very quickly because the nuclear reactors produce much more energy than any other type of facility for this purpose. It is also the cleanest and most environmentally friendly from any major type of production of energy.
Unfortunately, the production of nuclear energy doesn't come without risks. Even though very rare, accidents do happen, and when they do they cause much more damage than any other facilities for the production of energy. A more recent example is the accident in F u k u s h i m a, Japan, which resulted in a large-scale movement of people out of the area, abandoning of everything in the surroundings, and the area will not be suitable for usage for a very, very long time because of the very high levels of radiation. The opponents of nuclear energy production used this accident to make a point, especially cause it was one that happened in one of the most advanced countries, and what kind of consequences it had there, let alone if it happened in other parts of the world.
Answer:
Below
Explanation:
The fault is always younger than the rocks it cuts across because in order to have cut across those rocks they have to have existed there already, making them older
Answer:
Half-life is defined as the time required by an unstable element to reduce half of its original value. All unstable elements have a decay rate and this half-life differs from element to element. These unstable elements are known as radioactive elements. It continuously decays until it becomes a stable one. These elements when decays release radiations which are harmful to lives.
This half-life plays an important role in the determination of the age of a rock or fossils. It is used in various types of radiometric dating methods.
For example, the half-life of Carbon-14 is approximately 5700 years and the half-life of Uranium-238 is 4.5 billion years.
Answer:
(A) The Coriolis force is the force that acts on an object due to the rotation of the earth. The basic rule of this force is that it causes the deflection of wind when it blows from one place to another. The magnitude of this Coriolis force directly depends upon the latitude at which the object is located. This force is maximum at the poles and minimum at the equator.
(B)- Correct answer is Option (2) i.e this force can indicate the wind direction in the northern and southern hemisphere,
When the air in a particular area becomes warm due to heating, then it becomes less dense and rises up. This area forms a low pressure zone. This low pressure zone is filled with the air from the high pressure zone. The wind that blows from the region of high pressure to the region of low pressure does not move in a straight line. Due to the Coriolis force, this wind gets deviate and reaches the low pressure zone.
<u>Thus, this force indicates the direction from which a wind blows in both the southern and the northern hemisphere. In the southern direction it moves in anticlockwise direction, whereas in the northern hemisphere it moves in clockwise direction.</u>
