To solve this exercise it is necessary to apply the equations related to the magnetic moment, that is, the amount of force that an image can exert on the electric currents and the torque that a magnetic field exerts on them.
The diple moment associated with an iron bar is given by,
Where,
Dipole momento associated with an Atom
N = Number of atoms
y previously given in the problem and its value is 2.8*10^{-23}J/T
The number of the atoms N, can be calculated as,
Where
Density
Molar Mass
A = Area
L = Length
Avogadro number
Then applying the equation about the dipole moment associated with an iron bar we have,
PART B) With the dipole moment we can now calculate the Torque in the system, which is
<em>Note: The angle generated is perpendicular, so it takes 90 ° for the calculation made.</em>
The displacement distance from my house to school never changes but the time it takes varies due to traffic and it's effects on my vehicle's speed and position in line at stop lights.
Explanation:
Surface runoff: Excessive water collected on the land due to rains, storms, water melts and from other sources flows over the earth surface.
Transpiration: Moisture in the plants are absorbed by the roots and distributed in all the parts of plant. Moisture present in the underside of the leaves get converted into water vapors and releases in atmosphere
Evaporation : In this process , liquid state of water is converted into gaseous state of water that is water vapors.
Condensation: After evaporation , the water vapors rises up towards the sky. As they rise in the atmosphere the temperature decrease due which these water vapors stars getting converted into small water droplets. These small water drops combines with particles of dust , gas to form clouds
Precipitation: Water released from the clouds in the form of rain.
