Explanation: Ecological succession, the process by which the structure of a biological community evolves over time. Two different types of succession primary and secondary have been distinguished The final stage of succession is a climax community, which is a very stable stage that can endure for hundreds of years.
Answer:
When one of charge is doubled, the magnitude of the force between them gets doubled.
Explanation:
The electric force between two electric charges is given by :
Here,
k is the electrostatic force
d is the separation between charges
are charges
If one of the charges is doubled in magnitude while maintaining the same separation between the charges, 
New force becomes,
When one of charge is doubled, the magnitude of the force between them gets doubled. Hence, this is the required solution.
Answer:
it means that species is extinct.

Answer:
Option D. 4.4 m/s²
Explanation:
The following data were obtained from the question:
Velocity (v) = 21 m/s
Radius (r) = 100 m
Centripetal acceleration (a) =.?
The centripetal acceleration of the car can be obtained as follow:
Centripetal acceleration (a) = Velocity square (v²) / radius (r)
a = v²/r
a = 21²/100
a = 441/100
a = 4.41 ≈ 4.4 m/s²
Therefore, the centripetal acceleration of the car is 4.4 m/s².
