Answer:

2.5 m/s

Explanation:

The speed of the animal is given by the ratio between the distance travelled by the animal and the time elapsed:

v=\frac{d}{t}

where d is the distance travelled and t the time elapsed. Note that this quantity is also equal to the slope of the curve.

In the time interval 0-20 s, we have

d = 50 m - 0 m = 50 m

t = 20 s - 0 s = 20 s

So, the speed is

v=\frac{50 m}{20 s}=2.5 m/s

When electrons are "lost" from an atom, the free movement of these electrons constitutes an electric current.

A dead organism is the same as a nonliving thing in science. <br> Fact: <br> Evidence:
nikitadnepr [17]

No that is false

But nonliving thing in science is like a piece of plastic cant breath eat die non living
