b) by the end of the fifth day, group b will be more than one cm taller than group a. eliminate
Explanation:
The correct prediction based on the data shown is that by the end of the fifth day, group B plants will be more than 1cm taller than group A plants.
let us examine the table closely;
Day Group A (Water Only) Plant Height (cm) Group B (Water and Fertilizer)
1 2.0 2.0
2 2.2 2.3
3 2.3 2.8
4 2.5 3.2
5 2.6 3.8
We can see that by the end of the fifth day, the height differences between the two plants, 3.8 - 2.6 = 1.2cm, this is greater than 1cm. This claim from the experiment is very correct.
Other predictions are false.

Answer:
a) the total circle of "initial" is Epot./Eel. and the total circle of "final" is Ekin.
b)intia: 0.5 * 50 * 4^2 = 400 J
final: 0 J = 0.5 * 50 * 0^2
Explanation:
c) in the initial phase the spring is compressed and so has Epot but then the Energie changes to be totally Ekin (in final phase) and so the Epot becomes 0

Answer:
Explanation:
Just use the Force formula.
F = M . A
Acceleration Formula
A = V - Vo / Time
So...
F = 845 . (30 - 2 / 0.9)
F = 845 . 20
F = 16900 N
