Answer:
this is because Steel is more difficult to magnetise and demagnetise but an iron core makes a temporary electromagnet because its lose its magnetism when the switch is open and and steel core is used to make a permanent electromagnet
Answer:
Hydrophobic interaction.
Explanation:
On the basis of the polarity and the dissolution of water, the molecules can be classified into the hydrophilic and hydrophobic molecules. The hydrophobic molecules can easily dissolve in the non polar solvents.
The hydrophobic interaction is important that exist between the non polar molecules. The hydrophobic interaction plays an important role in the biological system as the lipids of the cell membrane are assisted together with the hydrophobic interaction. The hydrocarbon tail is non polar molecules that contains hydrophobic interaction within it.
Thus, the correct answer is hydrophobic interaction.
Answer:
No, or at least not yet. there small and dont do much improvment. If they were much bigger and sucked better, including some touch-ups here and there, they would have a bigger effect on removing sea urchins.
Explanation:
