Answer:
we got time and velocity over time.
so the distance is again the area underneath the graph
for a triangle with known base and height it's
4*10 / 2
distance traveled is 20
deceleration occurs when velocity decreases. that happens from t=2 till t=4
in 2 time-units we loose 10 units of velocity, so we decelerate by 5 units per 1 time
a (from t=2 to t=4) = -5v/t
So first of all, you might run out of food, which means that there wont be enough to sustain too many animals/people.
Or, you could simply run out of the space to have any more offspring.
One final one is the introduction of a new predator, which would eat the population, making the growth unpredictable.
Hope this helped!!!! :D
<h3><u>Answer;</u></h3>
A compound which is a pure substance
<h3><u>Explanation;</u></h3>
- <em><u>A pure substance is a substance with a definite and constant composition and distinct chemical properties. Pure substance can either be a compound or an element.</u></em>
- <em><u>Compound is a substance made of two or more elements that can be broken down by chemical means. therefore, Chemical reaction is the only way to separate a compound into its elements</u></em>
- Element on the other hand is a pure substance that is composed of only one type of atom. Unlike compounds pure substances can not be broken down by chemical means.
