Answer:
The correct option is;
(b) The end A of the solenoid behaves like a north pole
Explanation:
According to Lenz's law we have that the induced emf direction in the solenoid due to the rapid introduction of the bar magnet will be such that the electric current induced will have a resultant magnet field that will oppose to the movement of the north pole of the bar magnet that resulted in the magnetic field
Therefore, the opposing magnetic pole to the north pole of a magnet is a north pole and the solenoid end A will act like the north pole.
C)negative if that’s not the answer it’s B
Answer is B since electric field lines flow from negative to positive not from positive to positive.
The answer would be oceanography.
In chemistry, hydrophobicity refers to the physical property of a molecule that is repelled from a mass of water.
Hydrophobic molecules tend to be a non-polar and thus prefers neutral molecules and non-polar solvents. Hydrophobic molecules in water often cluster together forming micelles. Water on hydrophobic surfaces will exhibit a high contact angle.
Examples of hydrophobic molecules include alkanes, oils, fats, and greasy substances in general. Hydrophobic materials are used for oil removal from water, the management of oil spills and chemical separation processes to remove non-polar from polar compounds.
