How is water introduced into rivers and streams?

As the water flows down, it may pick up more water from other small streams, springs or or from rain or snow melt. ... Small rivers and streams may join together to become larger rivers. Eventually all this water from rivers and streams will run into the ocean or an inland body of water like a lake.

A) Independent

B) Dependent

C) Mass

Explanation:

The speed applied to the physics cart is manipulated. This doesn't depend on another variable. Thus, speed is the (independent) variable.

The cart accelerates due to the speed applied to the cart. Acceleration depends on the speed applied. Thus, acceleration is therefore the (dependent) variable.

A “constant” is a parameter that remains the same regardless of the variables.

One parameter of the cart that is held constant is the (mass).
