The time needed to form a soil depends on the latitude: in environments characterized by a mild climate, it takes 200-400 years<span> to form 1 cm of soil. in wet tropical areas soil formation is faster, as it takes</span>200 years<span>. in order to accumulate enough substances to make a soil fertile it takes </span>3000 years<span>.
Hope it helps! :-)</span>
Answer:
The mutual inductance is 
Explanation:
From the question we are told that
The number of turns per unit length is 
The radius is 
The number of turns of the solenoid is 
Generally the mutual inductance of the system is mathematically represented as
Where A is the cross-sectional area of the system which is mathematically represented as
substituting values
also 
is the permeability of free space with the value 
So
Answer:
Between 0 and 1 seconds (B)
Explanation:
The velocity of the car over time is represented by the line graphed here
the steeper the line, the greater change in velocity that occurred in a given time frame.
The steepest portion of the line is between 0-1 seconds, which means that the greatest rate of change occurred between 0-1 seconds.
(acceleration is the rate of change)
You would divide 6 into 1000 so your answer is B. 166
