Remember, that while sped is constant, acceleration is not. Acceleration is when velicity changes. So the graph which shows the slop <span>of a velocity vs time describes acceleration.
</span>If we have the straight line on the graph it means that the slope is always the same whereas the <span>non-linear graphs has a variable slope that changes depending on your point in the graph.
</span>To conclude - if your graph is not a straight line it has variable acc at many points.<span>

How do the processes of weathering, erosion, and deposition affect the ecoregions of Texas? Give a specific example of how each
NISA [10]

Answer:

Weathering, erosion, and deposition from the terrestrial surface topography and soil characteristics. These processes, for example, have formed a variety of landforms in Texas like beaches, plateaus, mountains, and canyons as well as soil types like fertile soil, clay-rich soil, and sandy soil. The combination of topography, soil, and climatic conditions in an area defines the types of habitats that the area can support this is crucial to ecoregion classification. Ten separate ecoregions occur in Texas including 1) East Texas Pineywoods, 2) Gulf Coast Prairies and Marshes, 3) Oak Woods and Prairies, 4) Blackland Prairie, 5) cross timbers and prairies (6) Rolling Plains, (7) High Plains, (8) TransPecos, (9) South Texas Plains, (Brush Country), and (10) Edwards Plateau. Such ecoregions are named for the major types of habitats topographical features (e.g. Edwards Plateau) present in their areas. The weathering, erosion, and deposition of each of these ecoregions have an important influence.

You nose out another runner to win the 100.000m dash. If your total time for the race was 11.8 seconds and you aced out the othe
daser333 [38]
You completed 100.000 m in 11.800 second

you aced out the other runner by 0.001 seconds

time taken by other runner to finish = 11.800 + 0.001 = 11.801s

speed of other runner = 100/11.801 m/s

distance covered by him in 11.8 s = 100/11.801 × 11.8 = 99.992 m

you won by = 100 - 99.992 = 0.008 meter

lapo4ka [179]

Answer:

      K =  \frac{h'}{8 m  \ \Delta x^2}K

Explanation:

The Heisenberg uncertainty principle is

          Δx Δp ≥ h' / 2

          h’ =\frac{h}{2\pi }

The kinetic energy of a particle is

          K = ½ m v²

           p = mv

           v = \frac{p}{m}

substitute

           K = \frac{1}{2}  \frac{p^2}{m}

from the uncertainty principle,

           Δp = \frac{h'}{2 \ \Delta x}

we substitute

          K = \frac{1}{2m} ( \frac{h'}{2 \ \Delta x})^2

          K =  \frac{h'}{8 m  \ \Delta x^2}
