In hooke's law if large if a large force produces a small displacement what does that say about the spring

In Hooke's law, if a large force produces a small displacement, what it says about the spring is that k is large.
This is because this is the formula: f = kx, so if f is large, and x is small, that means that k will be large as well.

An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to move. 

Iassume the answer is 75 feet. inwards to outwards rather than outwards to inwards. probably be 75.hachures are stokes drawn in direction of the steepest slope. a series of short parallel lines drawn on a map to indicate topographic relief. it is actually called hachures on contour lines. the small marks in the center of the feature are called hachures.observe the picture attached
