Explanation:
D) 75 J
Energy is neither related nor destroyed- it's simply converted to different forms. Forces are vectors with both mass and acceleration; they are interactions that have the ability to change an object's motion. As objects move, their potential energy (apprx 100 J) is converted to kinetic energy. However, friction a resistive force, which is formed from the conversion of an object's kinetic energy into heat energy, as two surfaces move along each other.
With the reduction of friction, the energy output should increase, as less energy is lost as heat. Thus, the output should be 75 J.

Answer:
19 cm
Explanation:
The total distance traveled by the toy cay would be 19 cm.
<em>The total distance traveled should not be mistaken for total displacement. </em><u><em>W</em></u><u>hile displacement measures the distance and direction from the starting position of the toy car relative to its final position, the total distance traveled is calculated by adding all the movements of the toy car together.</u> Hence;
Total distance traveled = 9 + 4 + 6 = 19 cm
Answer:
B this is because it is specifically a man made lake with only catfish.
Answer:
In an open system matter and energy can be transferred ·
In a closed system only energy can be exchanged ·
In an isolated system neither matter nor energy can be exchanged · The cell has to be an open system because it needs to exchange matter and energy and the only way to do so is through an open system ·
As an open system the cell allows nutrients to enter the cell and waste products to exit the cell ·
The cell does this through the use of a semi-permeable membrane

I think weather Bc I’ve read that that happens from wind
