Answer:
Her speed is 9.8 meter per second
Explanation:
Newton's second law states that acceleration (a) is related with force (F) by:
(1)
Here the only force acting on the firefighter is the weight F=mg so (1) is:
Solving for a:
Now with the acceleration we can use the Galileo's kinematic equation:
(2)
With Vf the final velocity, Vo the initial velocity and Δx the displacement, because the firefighter stars from rest Vo=0 so (2) is:
Solving for Vf
D
Abiotic components are the non-living components in an ecosystem, like water, minerals, sunlight and air.
Biotic components are the living components that make up an ecosystem, like plants and animals. So bacteria is not an example of an abiotic component.
