An automobile moving at 20m/s slows to a stop in 6.5
seconds. find the acceration of the car.

-3.1 m/s²

Explanation:

Given data

We can determine the acceleration of the automobile using the following kinematic expression.

a = Δv / t

a = vf - v₀ / t

a = (0 m/s - 20 m/s) / 6.5 s

a = -3.1 m/s²

water pollution kills aquatic life. aquatic life includes algae and other plant life that use photosynthesis. photosynthesis takes   c02 out of the air.  

c02is a greenhouse gas.

answer: they produce more slow than unicellular organisms.
