C. 190
Round each number
55→60.
60→60
65→70
Then add all of your rounded numbers.
60+60+70=190
Answer:
Step-by-step explanation:
In this system we have the force of the spring and the gravitational force. The equation that describes that is
where y0 is the equilibrium position when the string is free and y0+y is the new equilibrium position when the object is hanged of the string. By replacing by derivatives we have
the solution for this differential equation is (by using the characterisic polynomial)
hope this helps!!
The magnitude of this number is far from 1, so it's low correlation
Since it's negative, so it's low negative correlation
For the first one it would be C.
