Answer:erosion
Explanation:
Erosion refers to the process by which land is worn away by natural forces or human activities
Answer: A device records the time it takes sound waves to travel from the surface to the ocean floor and back again. Sound waves travel through water at a known speed. Once scientists know the travel time of the wave, they can calculate the distance to the ocean floor.
Explanation:
Answer:
Explanation:
Given the magnitude of the forces, 7N and 2N, the minimum combining force acting on the forces are when the force's is acting in opposite direction.
Magnitude of the force in opposite direction is 7N - 5N = 2N
The maximum combining force occurs when they act in the same direction. Magnitude of the force in the same direction is 5N+7N = 12N
Hence the range of magnitude requires is 2N≤F≤12N
Total energy will remain the same
