There are several ways they interact with each other.
Mechanically: Erosion, Mass movement, Sedimentation
Acceleration = velocity/ time
Acceleration = 0.7-0.3 /30= 0.01 m/s^2
Notice that velocity is calculated the final speed minus the initial !
Answer
The Value of r = 0.127
Explanation:
The mathematical representation of the two resistors connected in series is
And from Ohm law
The mathematical representation of the two resistors connected in parallel is
From the question
=>
Dividing equation 2 with equation 1
=>
We are told that
From equation 3
Using the quadratic formula
a = 1 b = -8 c =1
Now r = 0.127 because it is the least value among the obtained values
