Which could describe the motion of an object? Select 3 correct answers. distance = 10 meters and displacement = 1 meter distance

Anit [1.1K]

Answer:

The three correct statements which could describe the motion of an object are:

distance = 10 meters and displacement = 1 meter

distance = 10 meters and displacement = 0

distance = 10 meters and displacement = 10 meters

Explanation:

Motion is the change of position of an object along any path. As such, the path can be rectilinear or along a curve whose direction is variable.

Two important characteristics used to describe a motion are the length of the path traveled and the final distance from the starting point.

The length of the path traveled is what distance describes. The final distance from the starting point to the final point is what displacement describes.

The maginitude of the displacement is the difference between the final position and the starting position.

When the path traveled is rectilinear, the distance and the magnitude of the displacement are the same.

When the path is not rectilinear, the distance (the length of the path) is always greater than the magnitude of the displacement.

Thus, as for the correct statements, you have:

distance = 10 meters and displacement = 1 meter

This means that the object traveled along a 10 meters path, but since it was not rectilinear, the difference between the final position and the starting position is just 1 meter.

distance = 10 meters and displacement = 0

This means that the object traveled 10 meters but it ended back in the very same place from which it departed (a complete turn around a table, for example).

distance = 10 meters and displacement = 10 meters

This means that the travel was in the trip was alogn a straight line, and the object traveled 10 meters and ended 10 meters away from the starting place.

As for the two incorrect statements:

distance = 0 and displacement = 10 meters

distance = 1 meter and displacement = 10 meters

It is not possible that the object ended up 10 meters away from where it was (the displacement), by traveling just 1 meter less than that.

Answer:

Biodiesel has a higher oxygen content (usually 10 to 12 percent) than petroleum diesel. ... Biodiesel is more chemically active as a solvent than petroleum diesel. As a result, it can be more aggressive to some materials that are normally considered safe for diesel fuel. Biodiesel is much less toxic than petroleum diesel.

Part f - question 6 of the us adopted and maintained a policy of minimal control of co2 emissions, what level would we expect it

nasty-shy [4]

It seems that you have missed the necessary details for us to answer this question, so I had to look for it. Anyway, here is the answer. If the US adopted and maintained a policy of minimal control of co2 emissions, the level that we would expect its emissions to be in 2020 is that WE CAN'T TELL FROM THIS DATA. Hope this helps.
