Final answer:
The statement that airbag sensors are broken down into only two groups is false; airbag sensors can belong to various groups. The statement about high-voltage wires being wrapped in an insulating material is false, while the part about insulating connectors holding them aloft is true.
Step-by-step explanation:
It's false that airbag sensors are broken down into only two groups. Airbag systems can have various types of sensors, including impact sensors, accelerometers, and pressure sensors. These sensors play a crucial role in determining when to deploy the airbags, ensuring they inflate at the correct moment to minimize serious injuries to passengers.
Regarding the statement about high-voltage wires, it is true that the high-voltage wires you see connected to tall metal-frame towers are held aloft by insulating connectors. However, these wires are not typically wrapped in an insulating material. They are usually bare because the air around them provides sufficient insulation, and it is not practical to insulate the long stretches of wire used in power transmission.
