Answer:
In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the macroscopic energy associated with a system. The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant.

Answer:
6.6
Step-by-step explanation:
The equation that used to determine the dimension is 2(2x+10) = 300 and the dimensions of the rectangular yard is 80 foot and 70 foot
Total length of the fence = 300 foot
Consider the width of the rectangular yard = x
The length of the rectangular yard = x + 10
The perimeter of the rectangle = 2(l + w)
Where l is the length and w is the width
Substitute the values in the equation
300 = 2(x+10 + x)
300 = 2(2x + 10)
4x + 20 = 300
4x = 300 - 20
4x = 280
x = 280/4
x = 70 foot
The length = x + 10
= 70 + 10
= 80 foot
Therefore, the equation is 2(2x+10) = 300 and dimensions are 80 foot and 70 foot
