why does velocity of a stream increase in the downstream direction despite the gradient decreasing in the downstream direction? group of answer choices there is much less obstruction to the flow in the headwaters region, and the channel is much smaller, allowing the water to move faster. there is less obstruction to flow in the headwaters region relative to the smaller, more turbulent channels of the lower gradient region. there is more obstruction to flow in the headwaters region relative to the larger, more placid-flowing channels of the lower gradient region. there is more obstruction to flow in the low-gradient areas of the channel relative to the slower-moving headwaters region of the flow.

Respuesta :

The Correct answer is D. There is more obstruction to flow in the low-gradient areas of the channel relative to the slower-moving headwaters region of the flow.

The pace is the directional speed of an object in movement as an illustration of its fee of change in role as located from a selected frame of reference and as measured by way of a specific trend of time (e.g. 60 km/h northbound). velocity is an essential concept in kinematics, the branch of classical mechanics that describes the motion of our bodies.

The pace is a bodily vector amount; both importance and direction are had to define it. The scalar absolute fee (magnitude) of velocity is called velocity, being a coherent derived unit whose quantity is measured in the SI (metric device) as meters in line with 2d (m/s or m⋅s−1). To have a consistent velocity, an object has to have a steady velocity in a constant route. constant path constrains the item to move in an immediate direction as a result, a steady pace way motion in a direct line at a consistent pace.
