Answer:
Swimmer A
Explanation:
The time required for a swimmer to cross a river is equal to the width of the river which is divided by the magnitude of the component of the velocity which is parallel to the width of the river.
In the given context, all the three swimmers A, B and C swims in a different angle relative to the direction of the flow of river. The swimmer A swims straight at a direction perpendicular to the direction of current of the river across the width of the river, so A will have the largest velocity component which is parallel to the width of the river. So the time taken by swimmer A will be the least to cross the river.
The answer is: Renewable energy resource.
The explanation for this completion exercise is shown below:
By definition, the Renewable energy is that the energy that is obtained from renewable resources. Renewable energy sources has taken on importance in recent years and plays an important role in the sustainable development of the planet.
Therefore, Agricultural waste used as fuel is an example of a Renewable energy resource, because you can obtain low emissions but high efficiency.
they are the lithosphere (land), hydrosphere (water), biosphere (living things), and atmosphere (air).
Explanation:
Displacement is the straight line distance from the starting position to the final position.
Person X walks halfway around circle. So her displacement is 100 m.
Person Y walks 3/4 of the way around. So his displacement is 50√2 m ≈ 70.7 m.
Person Z walks completely around the circle, so their displacement is 0 m.
Therefore:
Z < Y < X
