Reaction force is the ball pulling up on the Earth. Every action has an equal and opposite reaction, so when the Earth pulls on the baseball, the baseball pulls back on the Earth with equal force

Nitro5315 is spot on.  And the reason the ball "falls down" to the ground but the Earth doesn't seem to "fall up" to meet the ball is because the Earth's mass is so much larger than the ball.  Nevertheless the Earth does in fact accelerate a little bit upward.

<h3><u>Answer;</u></h3>

  = 64 N/m

<h3><u>Explanation</u>;</h3>

According to Hooke's Law for a helical spring or an elastic material, extensional force is directly proportional to the distance the material has extended.

F = ke; where F is the extension force, k is the spring constant, and e is the distance extended.

Thus;

k = F/e

  = 44N/0.69 m

  = 63.768 N/m

  <u>= 64 N/m</u>

<h3><u>Explanation;</u></h3>
  • The collision and joining of crustal fragments to a continent is called the continental<em><u> </u></em><em><u>accretion</u></em><em><u>.</u></em>
  • <em><u>Accretion is the process through which materials such as sediment, volcanic arcs, or seamounts or blocks,  etc. are added to the tectonic plate or land mass.</u></em> Many astronomical bodies, such as stars, galaxies or planets are formed by this process.
  • Where the process of accretion has occurred the tectonic plates may have dense basaltic rocks which are indicative of oceanic lithosphere.
