Answer:
Completion between two organism is when they fight over resources inadvertently causing the use and destruction of recourses making it more scares. if they don't adapt they die out.
Explanation:
A,D,E
8,3375*10^-9 N
Attached is the solution
Acceleration = 9 × 10^5 m/s^2 ( deceleration )
From the first equation of motion:
V = u + at
15000 = 30000 + 60a
a = ( 15000-30000)/60
a = 9 × 10^5 m/s^2
The number of protons in the atom!
