We know, Applied force(f) = Spring constant (K) * Extension of material (x)
Here, f = 12 N
x = 0.070 m
Substitute their values,
12 = k * 0.070
k = 12 / 0.070
k = 171.43 N/m
In short, Your Answer would be 171.43 N/m
Hope this helps!
Answer: I could be wrong but according to Newton’s third law of motion, for every action, there is an equal and opposite action, so for every answer, just find an arrow that’s the same size as the blue one and make the arrow point in the opposite direction that the blue one is pointing to
It would take 3.6 hours for a car to travel 200 km going 55 km/hr.
