Answer 12

Why are metals used within most electronic devices and wires? In three to five sentences, apply your knowledge of conductivity to explain.(4 points)

Answer 13

[AI-generated answer — Bot GPT 3.5]

Metals are used within most electronic devices and wires because they are excellent conductors of electricity. The outer electrons of metal atoms are delocalized and can move freely, allowing the flow of electric current. This high electrical conductivity makes metals ideal for carrying and transmitting electrical signals efficiently. Additionally, metals have low resistance, which minimizes energy loss as current passes through them. These properties make metals a fundamental component in electronic circuits and devices, ensuring reliable performance and efficient energy transfer.

Answer 15

[AI-generated answer — Bot GPT 3.5]

Metals are commonly used in electronic devices and wires due to their high electrical conductivity. The delocalized outer electrons in metal atoms can move freely, facilitating the flow of electric current with minimal resistance. This property allows for efficient transmission of electrical signals within electronic circuits. The low resistance of metals helps minimize energy loss as electricity travels through wires, ensuring the effective operation of electronic devices. Overall, the conductivity of metals makes them essential components in electronic systems, providing reliable performance and efficient energy transfer.

Answer 16

In 8 to 10 sentences, identify two components of the control subsystem of a vehicle, and use them to explain why driving can be hazardous when the control subsystem is not functioning properly.(4 points)

Answer 17

[AI-generated answer — Bot GPT 3.5]

Two components of the control subsystem of a vehicle are the steering system and the braking system. The steering system allows the driver to control the direction of the vehicle, while the braking system enables the driver to slow down or stop the vehicle when necessary. When the control subsystem is not functioning properly, driving can become hazardous. For example, if the steering system malfunctions, the driver may lose the ability to steer the vehicle effectively, leading to loss of control and potential accidents. Similarly, if the braking system fails, the driver may be unable to slow down or stop the vehicle in time to avoid collisions or obstacles on the road. These malfunctions can pose serious risks to the safety of both the driver and others on the road. In conclusion, the proper functioning of the control subsystem is crucial for safe driving, and any issues with components like the steering or braking systems can significantly increase the hazards associated with operating a vehicle.
