<span>The water is clearer, has higher oxygen levels, and freshwater fish such as trout and heterotrophs can be found. In the middle of the river, the width increases, so do the species of aquatic green plants and algae. Toward the mouth of the river, the water becomes murky from all the sediments that it has picked up upstream.<span>

With that information, you can determine the object's speed.
Just divide the distance covered by the time to cover the distance.
If you also know the direction the object moved, then you can
determine its velocity. If you don't, then you can't.
Solar energy, wind energy, hydro energy
SONAR stands for "sound navigation and ranging,” and it is used to map and explore the ocean floor.
When you throw the ball in the air it is considered kinetic energy. Once the ball reaches its max height, it stops moving and all kinetic energy turns into potential energy. So when the ball is at its highest point.
