Final answer:
The statement about high-voltage wires having insulating material wrapped around them is false as they are typically bare. The recommendation to keep credit cards away from permanent magnets to protect their magnetic strips is true. Lastly, the Iroquois Confederacy was not entirely neutral during the Revolutionary War; its member tribes took different sides.
Step-by-step explanation:
The statement about high-voltage wires being held aloft by insulating connectors and wrapped in insulating material is false. These wires are indeed held up by insulating connectors to prevent electrical current from reaching the ground or the metal-frame towers that support them. However, the wires themselves are not wrapped in insulating material; they are typically bare, which allows for more efficient transmission of electricity over long distances. Insulators at points of support restrict the flow of the electrical current to the intended path along the wire.
In the case of magnetic fields and credit cards, the statement that it is not recommended to place credit cards with magnetic strips near permanent magnets is true. Magnetic strips on credit cards can be demagnetized or the data encoded on them can get corrupted when they are subjected to strong magnetic fields. This is why it’s advised to keep credit cards away from permanent magnets to protect the information stored on the magnetic strip.
Regarding the statement on the neutrality of the Iroquois Confederacy during the Revolutionary War, it is false. The Iroquois Confederacy, also known as the Haudenosaunee, was split on the issue of the American Revolutionary War. Some tribes within the confederacy sided with the American colonists while others sided with the British.
