This is false because an object can also be pushed by force and isn't always have to be pulled by a force.
If the cross-section of a wire of fixed length is doubled, the resistance of that wire change into doubled.We know that <span>the total </span>length<span> of the wires will </span>affect<span> the amount of </span>resistance. <span> The longer the wire, the more </span>resistance<span> that there will be so the answer is doubled.</span>
Magnetic domain is defined as a group of atoms with magnetic fields.
A piece of iron can only become a magnet when the magnetic domain aligns.
Since we have an unmagnetized piece of iron, this means that its domain is not aligned. However, this does not mean that the domain does not exist.
Based on the above, the best choice would be:
There arr domains, but domains are oriented randomly.
Hope this helps :)
