<h3><u>Answer;</u></h3>
acceleration= 2 m/s²
<h3><u>Explanation;</u></h3>
From the second Newton's Law of motion the resultant force is directly proportional to the rate of change in momentum.
That is;
F = ma
Thus; F = 100 N, m = 50 kg
a = F/m
= 100/50
= 2 m/s²
Answer:
<em>Hypotheses may vary. Most students will probably state that ecosystems at
</em>
<em>high altitudes will support little vegetation. </em>
Explanation:
Ecosystem distribution is different at different places. Regions at high elevations might usually have low varieties of plants and animals but it cannot be true for every ecosystem located as higher altitudes.
Some communities might be well adapted to live in the cold and hence progress rapidly.
Answer:
Scientists have been concerned that human activities could cause more plants and animals to become extinct than any point in the past. Along with human-made changes in climate (see above), some of these extinctions could be caused by overhunting, overfishing, invasive species, or habitat loss
