Answer :
When we see the words "Which statement ... ", we know right away that there
will be a list of choices, and we're expected to select our answer from that list.
Strangely, the list of answer-choices for this question has been lost.
Similarly, when we see the words "The picture shows ... ", it's hard to fight
the impulse to look around. In the present situation, that's missing too.
If the diver is just standing there, then the reaction force provided by the cliff
against his feet must be exactly equal to his weight. If the vertical forces acting
on the soles of his feet were not balanced, then his feet would be accelerating
vertically.
His weight is (mass) x (gravity) =
(93 kg) x (9.8 m/s²) = 911.4 newtons (about 205 pounds) .
That's also the strength of the upward reaction force provided by the cliff.
Final answer:
In this situation, the reaction force to Earth's gravity acting on the professional diver is the normal force.
Explanation:
In this situation, the reaction force to Earth's gravity acting on the professional diver is the normal force. The normal force is the force exerted by a surface to support the weight of an object resting on it.
On a level surface, like the edge of a cliff in this case, the normal force is equal in magnitude and opposite in direction to the force of gravity acting on the diver. It prevents the diver from sinking into the surface and provides the necessary support to keep the diver in place.
Therefore, the statement that best describes the reaction force to Earth's gravity in this situation is that it is the normal force exerted by the surface.
