Why are metals used within most electronic devices and wires? In three to five sentences, apply your knowledge of conductivity to explain.
Metals are used within most electronic devices and wires because they are good conductors of electricity. Metals have low electrical resistance, which means that electrons can flow through them easily. This allows electricity to be transmitted quickly and efficiently through wires, making them ideal for conducting electricity through electronic devices and circuits. Additionally, metals can be easily shaped and molded, making it easier to manufacture electronic components and devices.
Red tape can be used to repair a broken taillight on a car. In one or two sentences, explain how different colors of light are transmitted, reflected, and absorbed by this kind of tape.
Different colors of light are absorbed and reflected differently by red tape. Red tape absorbs all colors of light except for red, which it reflects. This means that when white light (which contains all colors of the spectrum) is shone on red tape, only the red part of the spectrum is reflected back, resulting in a red appearance.
You want to make a photo album for your friend. In three to five sentences, describe at least one advantage and one disadvantage of choosing a digital photo album rather than a physical one. Analyze a potential solution to the disadvantage.
One advantage of choosing a digital photo album over a physical one is that you can store a large number of photos in one place without taking up physical space. This makes it easier to manage and organize photos. However, a disadvantage is that digital photo albums can be lost or deleted if a computer or storage device crashes. One potential solution to this disadvantage is to keep multiple backups of your digital photos in different locations, such as on an external hard drive or in cloud storage.
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 and braking systems. When the control subsystem is not functioning properly, it can lead to a loss of control over the vehicle. If the steering system fails, the driver may be unable to steer the vehicle or may veer off the road. If the braking system fails, the driver may be unable to slow down or stop the vehicle, which can result in accidents or collisions. These failures can result in hazardous driving situations where the driver is unable to control the vehicle, putting themselves and others at risk.
