The pressure of a submerged object in a fluid is given by:
where ρ is the density of the fluis, g is the acceleration of gravity, h is the depth of the object and Patm is the pressure of the atmosphere. In this case we know that:
• The density of water is 1000 kg/m^3
,
• The acceleration of gravity is 9.8 m/s^2
,
• The depth of the object is 3 km, that is, 3000 m.
,
• The atmospheric pressure is 101325 pascals.
Plugging these values in the equation given above we have:
Therefore, the pressure at this depth is 2.95x10^7 Pa.
Flowing electrons produce a magnetic field, and spinning magnets cause an electric current to flow. Hope this helps you out.
Answer:
<h3>The 28 loops wound on the square armature</h3>
Explanation:
Peak output voltage V
Area of square armature
Magnetic field T
Angular frequency
According to the law of electromagnetic induction,
Where number of loops of wire.
≅ 28
Thus, 28 loops of wire should be wound on the square armature.
