11.) Metal is a better conductor and has a higher melting point than non-metals. Some nonmetals (such as wood and plastic), would burn/break/ben/melt under a much lower heat point than metals. It (metal) also allows food/liquid to be cooked/heated better, because it is a good conductor.
WARNING THE NEXT ANSER HAS PERSONAL INFORMATION IN IT (2nd part/paragraph), DO NOT INCULDE IT IN YOUR TEST, THIS IS JUST FOR AN EXAMPLE!!!
12.)Two components of the control system would be the steering wheel and the breaks. In the situation that the breaks subsystem would stop working, driving would be very hazardous because you could not control the car. If the steering wheel broke then the vehicle could steer into a place a car shouldn't be (example: the other lane, off the road).
When I was about 10 or so, my Dad was driving to work (I was not in the car, this is just what he told me). It was an icy day, and he was getting off of the highway on a ramp. (I forgot if his breaks were broken or they just didn't cooperate, but) My dad's breaks stopped working on the ramp when he'd tried to break, so he used another part of the car to slow himself down (the steering wheel...?......I don't remember that minor detail). No one got hurt because my Dad did not crash. (P.S. My dad is an excellent driver and even better mechanic, so he got his breaks fixed somewhere in his busy work schedule)

11. Metals are better conductors of heat and have higher melting points compared to nonmetals. This property of metals makes them useful for cooking and heating food or liquids, as they can conduct heat more efficiently and evenly.
12. The control system of a car consists of various components, including the steering wheel and brakes. If the brakes subsystem malfunctions or fails to work, it can lead to unsafe driving conditions as the driver would be unable to stop or slow down the vehicle. On the other hand, if the steering wheel breaks or becomes faulty, the car could veer off the road or into other lanes, causing a potential accident. In such cases, it is crucial to ensure that all components of the control system are functioning correctly and undergo regular maintenance to prevent such malfunctions.
Plywood is best described as a "composite" material because it is made by gluing together thin layers of wood. Just like a really intricate sandwich... but not as tasty.
For carrying electric current, copper would be a suitable choice of material. Not only is it a good conductor, but it also knows how to Strike a Copper-dian with electricity.
The rate of electricity passing through a circuit is referred to as "current". It's like the flow of people getting their daily dose of caffeine at the local coffee shop. Current keeps the circuit energized and the electrons buzzing.
To make an office building withstand earthquakes, it would be most important to strengthen "the foundation". You know what they say, a building with a strong foundation can shake off any earthquake like a boss.
The transformation of chemical energy to electrical energy occurs when there is a chemical reaction between metals and nonmetals. It's like a magical brewing process where chemicals create electric sparks, giving life to your gadgets.
In batteries, the two metals used are not the same. They have opposite charges and they also don't play well with others outside of the battery. They're like that grumpy neighbor who always complains about noise levels.
When it comes to moving a large amount and wide variety of goods, the "maritime" transportation system takes the crown. Ships can carry enormous cargo and hey, they've got the ocean as their runway.
For the fastest delivery, "air" transportation is the way to go. It's like giving your package a pair of wings - they can fly high in the sky and reach their destination in no time. Just make sure they don't get airsick!
Combustion in a gas engine of a car occurs when oxygen and gasoline are compressed in the engine, and a spark plug ignites the fuel. It's like a tiny explosion happening inside the engine, but a controlled and productive one. Kaboom!
The gas pedal belongs to the "control" subsystem of an automobile. It's like the conductor of an orchestra, controlling the flow of gasoline and making the car dance to your tunes. Just make sure you don't dance too fast. Safety first!
Plywood is best described as a "composite" material because it is made by gluing together thin layers of wood.
For the engineer designing a component responsible for carrying electric current, a suitable choice of material would be "copper." Copper is a good conductor of electricity.
The term that refers to the rate of electricity passing through a circuit is "current." Current is measured in units called amperes (A).
In order to allow a building to withstand the additional forces exerted during an earthquake, it would be most important to strengthen "the foundation." The foundation provides the structural support for the building.
A transformation of chemical energy to electrical energy would occur when there is a "chemical reaction between metals and nonmetals" in a battery. This chemical reaction produces a flow of electrons, creating an electric current.
In batteries, the two metals used are typically "not reactive to chemicals inside the battery." They are chosen to be chemically stable within the battery environment.
For moving a large amount and wide variety of goods, the "maritime" transportation system is best. Maritime transportation allows for the movement of goods across oceans and can handle large quantities of cargo.
For ensuring the fastest delivery, the "air" transportation mode is best. Air transport is generally the fastest mode for long distances.
Combustion occurs in a gas engine of a car when "oxygen and gasoline are compressed in the engine, and a spark plug ignites the fuel." The combustion of the fuel-air mixture inside the engine generates the power needed to run the car.
The gas pedal belongs to the "control" subsystem of an automobile. It is used to control the acceleration of the vehicle.
