Answer:
[tex]\frac{1}{8}[/tex] of its original size would be left
Explanation:
The half life of the isotope is the time required for it to decay to half of its original size.
Half life of the isotope = 200 years
So that, after 600 years the material that would be left would be;
let the original size of the material be represented by x.
200 years = [tex]\frac{1}{2}[/tex] x would remain
400 years = [tex]\frac{1}{4}[/tex] x would remain
600 years = [tex]\frac{1}{8}[/tex] x would remain
Thus after 600 years, [tex]\frac{1}{8}[/tex] of its original size would be left.

The correct answer is C. Currents
Explanation
The image in the question is a map showing the North Atlantic and the Caribbean Sea. In the middle of these is a red arrow that marks the Gulf Stream.

It moves in a current towards the north of the Atlantic where it is losing temperature due to the difference in the incidence of the solar rays. Therefore, the correct answer is C. Currents.

(a) gold and minerals
(b) the money in the Bank
(c) the people
(d) all
Answer:
a) gold and minerals
Explanation:
A national resource is a resource controlled by the government, whether it is at the state or national level. For example, wildlife, railways, gold and minerals. Therefore, correct option is A.

1 - Individual Resources : Individual resources are those owned by private individuals. For examples : house, car, book, etc.
2 - Community Resources : Resources that belong to all community members. Owned by all members of the community. For example : public parks, play ground, etc.
3 - National resources : Those resources that are under the control of a state or union government are considered national resources. For example : all mineral resources, like water, land, forest and wild life.
4 - International Resources : There are international institutions that control all areas that are not under national control. As an example, areas beyond the exclusive economic zone are considered part of the open ocean and can only be utilized by international institutions if they are given permission by them.
Thus, gold and minerals are national resources. Because, they are under the control of a state or union government & are considered as national resources.
