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.
The oceanic lithosphere is a layer on the Earth's crust that consists of rocks of the mantle.
<h3>What is the lithosphere?</h3>
The lithosphere can be defined as the outer rock layer present on the Earth's surface.
The oceanic lithosphere is composed of different rocks of the mantle such as, among others, gabbro and/or basalt.
The structure of the oceanic lithosphere is similar around the world because it is slender compared to the continental lithosphere and always determined by the supply of magma.
In conclusion, the oceanic lithosphere is a layer on the Earth's crust that consists of rocks of the mantle.

Answer : Magnitude
Explanation :
In a value, the magnitude is represented by its units. It can be adopted by convention or by law.
Magnitude of any unit is used to measure the same kind of quantity.
For example: The unit of length which is a physical quantity is meter (m).
So, magnitude is correct answer.
Solar cells are used to trap sunlight energy (light energy) and convert it to electric energy for domestic and other purposes.
