Metals are used within most electronic devices and wires because they are excellent conductors of electricity. Metals have a high density of free electrons that can move easily through the material, allowing for the flow of electrical current. This conductivity property of metals helps to efficiently transmit and distribute electrical signals within electronic devices. Additionally, metals are malleable and ductile, making it easy to form them into the necessary shapes and sizes required for electronic components. Overall, the use of metals in electronics helps to ensure reliable and efficient performance of the devices.
In three to six 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)
Two components of the control subsystem of a vehicle are the brakes and the steering system. The brakes are responsible for bringing the vehicle to a stop and maintaining control during deceleration, while the steering system allows the driver to maneuver the vehicle in the desired direction. If the control subsystem is not functioning properly, such as brakes failing or the steering system malfunctioning, driving can become hazardous. For example, without properly functioning brakes, the driver may not be able to stop the vehicle in time to avoid a collision, putting themselves and others at risk. Similarly, a malfunctioning steering system can make it difficult for the driver to control the direction of the vehicle, leading to potential accidents or loss of control. Overall, a malfunctioning control subsystem can significantly increase the likelihood of accidents and pose a threat to the safety of the driver and passengers.
