Answer:
Step-by-step explanation:
Hooke's Law applies here, which is a linear relationship. It would be easier to solve this using proportions with N of force on the top and the amount of stretch in cm on the bottom. Set up with our unknown, the number of cm:
and cross multiply:
20x = 300 so
x = 15 cm
Whats the question exactly??
The difference is -10 because
9-10= 1
-1-10= -11
-11-10= -21
common difference means you add and common ratios means you multiply.
hope this helps!
