Explanation:
Both graphs show plotted points forming a curved line. Curved lines have changing slope; they may start with a very small slope and begin curving sharply (either upwards or downwards) towards a large slope. In either case, the curved line of changing slope is a sign of accelerated motion (i.e., changing velocity).

Hi there!
Recall Newton's Second Law:
∑F = Net force (N)
m = mass (kg)
a = acceleration (m/s²)
Rearrange the equation to solve for mass.
Working equation:
Plug in the given values:
<span>Contour lines on a topographic map show elevation of the ground. Contour lines on a map that are constructed by connecting points of equal elevation .
</span><span>
</span><span>some general characteristics of contour lines:
</span><span>1) They do not cross each other, split or divide.
</span><span>2) Steep slopes are reprented by contour lines spaced closely. Gentle slopes are reprented by contour lines spaced far apart
</span><span>3) Contour lines trend up valleys and form a "V" or a "U" where they cross a stream.</span>
