Answer:
The basic working principle of a wind turbine is to convert the mechanical energy from the wind into rotational energy at the mill, then the rotation of the mill is used to rotate the generator, which will eventually generate electricity. This tool serves to change the low rotation of the wheel into high rotation.
Chemical reaction: HSO₄⁻(aq) ⇄ H⁺(aq) + SO₄²⁻(aq);
or HSO₄⁻(aq) + H₂O(l) ⇄ H₃O⁺(aq) + SO₄²⁻(aq)
Ka₂ = [H⁺]·[SO₄²⁻]/[HSO₄⁻]; Ka₂ = 1.0·10⁻².
[H⁺] is equilibrium concentration of hydrogen cations.
[SO₄²⁻] is equilibrium concentration of sulfate anions.
[HSO₄⁻] is equilibrium concentration of hydrogensulfate(bisulfate) anions.
Answer:
The answer to the question is
The resultant ground reaction force exerted by the floor on the volleyball player's shoes = 2088.06 N
Explanation:
To solve the queston we list out the variables thus
Mass of volley ball player = 80 kg
Normal force exerted on her shoes by the floor N =2000 N
friction force, f, exerted on her shoes backwards = 600 N
The resultant ground reactive force, R, is given by
R² = N² + f² = 2000² + 600² = 4000000 + 360000 = 4360000
Therefore R = √(4360000) = 2088.06 N
The direction of the force = atan (2000/600) = 73.3 ° clocwise or 106.699 ° counter clockwise
The Earth can be divided into one of two ways – mechanically or chemically. Mechanically – or rheological, meaning the study of liquid states – it can be divided into the lithosphere, asthenosphere, mesospheric mantle, outer core, and the inner core.
