Answer:
2160.26 N.
Explanation:
From the question,
The total energy of the woman = work done by the water.
mg(h+d) = F'×d.......................... Equation 1
m = mass of the the woman, g= acceleration due to gravity, h = height of the platform, d = depth of water reached by the woman, F'= Resistance force exerted on her by the water.
make F' the subject of the equation
F' = mg(h+d)/d............................ Equation 2
Given: m = 65.0 kg, g = 9.8 m/s², h = 11 m, d = 4.6 m.
Substitute into equation 2
F' = 65(9.8)(11+4.6)/4.6
F' = 9937.2/4.6
F' = 2160.26 N.
You are crossing the event horizon of a black hole
When you are feeling like spaghetti and you are normally only about 2 meters tall, you are now about 25 meters long, then look up over your head, you see things moving pretty quickly in the universe but that lasts only a brief instant, and then all contact with the universe is lost, you are crossing the event horizon of a black hole.
<h3>What happens when you are crossing the event horizon of a black hole?</h3>
- The point of no return is the black hole's event horizon.
- Anything that continues beyond this point will be absorbed by the black hole and disappear from the known universe forever.
- The black hole's gravity is so strong at the event horizon that it cannot be overcome or resisted by any mechanical force.
<h3>Is it possible to endure inside an event horizon?</h3>
- As a result, the individual would survive and gently float over the event horizon of the black hole without being harmed or stretched into a long, thin noodle.
<h3>What occurs beyond the horizon of the event?</h3>
- A singularity is a truly tiny point that lies beyond the event horizon where gravity is so strong that space-time itself is infinitely bent.
- The principles of physics as they exist presently break down at this point, making any hypotheses about what lies beyond mere conjecture.

Each magnet has a north pole and a south pole. We know that, from having played with bar magnets in our childhood, that a magnet's north pole will repel another magnet's north pole and attract its south pole.
From this diagram it is easy to see that the two lower bar magnets not only repel each other, but they are quite attracted to each other since their north and south poles are close together.
Therefore the region between the lower two magnets has the least force of repulsion.
