Answer:
17. 7.61×10³ N
18. 9.51 m/s²
19. maybe you want 29.375 N
Explanation:
17. Use the given formula for force. Fill in the masses and radius. The distance from the earth is in addition to the radius of the earth.
__
18. Make use of the relation ...
F = ma
a = F/m = (7.61×10³ N)/(800 kg)
a ≈ 9.51 m/s²
__
19. The acceleration of the runner is ...
a = ∆v/∆t = (9 m/s - 4 m/s)/(8 s) = (5/8) m/s²
The force she is applying to the ground to accelerate herself is ...
F = ma = (47 kg)(5/8 m/s²) = 29.375 N
The amount of force applied to the tape depends on its mass and the effect the tape has on the runner's acceleration. There is insufficient information in the problem statement to permit an answer to the question.

Explanation:
A population is a total number of organisms of a particular species, sharing a particular characteristic of interest, most often that of living in a given area.
The characterictics of population of organisms in a given habitat include:
1) Inhabiting the same general area - closely related species of birds, insects etc live in the same environmental conditions and physical area
2) belonging to the same species - organisms of the same species usually live together mainly for breeding purposes.
