Answer:
Climate change
Explanation:
A group of change in climate system that is persistent for up to 30 years is called Climate change
B.) Forestry and Mining because it is a great source for metals and minerals such as copper, gold, iron, nicklel, uranium, zinc, and silver.
Answer:
Yemen's principal natural resources are oil and natural gas as well as agriculturally productive land in the west. Other natural resources include fish and seafood, rock salt, marble, and major unexplored deposits of coal, gold, lead, nickel, and copper. The most common crops are cereals such as millet, corn (maize), wheat, barley, and sorghum; myriad vegetables from a burgeoning truck farm industry have appeared on the market in recent years.
<h2>Answer:</h2>
The Work 
done by a Force 
refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path.
It should be noted that it is a scalar magnitude, and its unit in the International System of Units is the Joule. Therefore, 1 Joule is the work done by a force of 1 Newton when moving an object, in the direction of the force, along 1 meter:
Now, when the applied force is constant and the direction of the force and the direction of the movement are parallel, the equation to calculate it is:
(1)
When they are not parallel, both directions form an angle, let's call it 
. In that case the expression to calculate the Work is:
(2)
For example, in order to pull the bicycle out of the garage, you have to apply a force along the distance 
to overcome the resistance of the weight of the bicycle.
In this case both (the force and the distance in the path) are parallel, so the work performed is the product of the force by the distance traveled , as shown in equation (1).
Hence:
>>>>This is the work
