Metals are used in electronic devices and wires because they are excellent conductors of electricity. Conductivity refers to the ability of a material to allow the flow of electricity through it. Metals have high electrical conductivity due to their atomic structure, which allows electrons to move easily through the material. This makes metals ideal for carrying electric currents in electronic devices and wires, ensuring efficient transfer of electricity throughout the device. Additionally, metals are also durable and strong, making them suitable for use in devices that require a steady and reliable flow of electricity.
In three to five 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.
Two components of the control subsystem of a vehicle are the steering system and the braking system. When the steering system is not functioning properly, the driver may have difficulty maintaining control of the vehicle, leading to swerving or veering off course. This can result in accidents, especially at high speeds or in emergency situations where quick and precise steering is necessary. Similarly, if the braking system is not working correctly, the driver may struggle to stop the vehicle in time to avoid collisions or obstacles on the road. Without proper functioning of both the steering and braking systems, driving can become hazardous and increase the risk of accidents and injuries.
