When cleaning up a local beach, students found many different particles that were in the water that affected the shoreline, like litter and gasoline. which of the following describe how these items would need to separated from the water? why? a. both gasoline and litter would need to be chemically separated from the water, because both form new bonds with the water. b. litter would need to be physically separated with water and gasoline would need to be chemically separated from water, because both form a mixture with the water. c. both gasoline and litter would need to be chemically separated from the water, because neither bonds with the water. d. both gasoline and litter would need to be physically separated from the water, because neither bonds with the water. (p.s. do teachers know about this? like fr)

Ответ:
The correct answer is D,
Ответ:
In regards to basic motion, the total energy is simply the sum of potential energy and kinetic energy. Potential energy is dependent with position.
Going up:
Potential energy increases, Kinetic energy decreases, Total energy is constant
Going down:
Potential energy decreases, Kinetic energy increases, Total energy is constant
Explanation:
