I believe this is True.
Hope this helps!
Answer:
Borders are imaginary lines that divide a nation, state, province or city from others. These dividing lines can be taken from geographic features, such as rivers, seas, lakes, mountains, etc .; or in geometric form, using lines as meridians and parallels; or for ethnic reasons, dividing populations based on languages, ethnic origin, etc.
Examples of each of these types of border are:
-Natural border between Argentina and Chile along the Andes Mountains, taking as the dividing line the highest point of the same.
-Geometric border between America and Canada on the west coast, taking the line of parallel 49 as division.
-Ethnic border between Pakistan and India, dividing both nations according to concepts of Islamic or Hindu religious affiliation.

Potential Energy
The potential energy gained is 43750 J
Explanation:
Potential energy is the energy by virtue of an object's position relative to the ground ie, the height of the other object.
For example, an object has more potential energy when it is on top of a two-story building than it does resting on the ground. That's because the object's relative position to the Earth gives it more energy.
Potential Energy is defined as
Potential energy = Mass * height
Given Mass M = 1250 N
Given height h = 35 m
So the potential energy = 1250 * 35 = 43750 J
Thus the potential energy is 43750 J
Simplifying 4m + 9 + 5m + -12 = 42 Reorder the terms: 9 + -12 + 4m + 5m = 42 Combine like terms: 9 + -12 = -3 -3 + 4m + 5m = 42 Combine like terms: 4m + 5m = 9m -3 + 9m = 42 Solving -3 + 9m = 42 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + 9m = 42 + 3 Combine like terms: -3 + 3 = 0 0 + 9m = 42 + 3 9m = 42 + 3 Combine like terms: 42 + 3 = 45 9m = 45 Divide each side by '9'. m = 5
