Marty is developing a new way to heat an airplane's windshield to prevent it from accumulating ice when in flight. A thin layer of clear, conductive material is injected between two layers of thick windshield plastic. A very small electric current is run through the inner material to keep the plastic layers warm. How might using a model help Marty develop his design? A. A model could be used for automobile windshields. B. Airplane manufacturers could be sold models to use in their new planes. C. Marty could use a model to discover a new type of plastic for windshields. D. A model could be used to test his design in a lab.

D: A model could be used to test his design in a lab

Explanation:

Engineers use models to help them develop new or improved technologies. Models allow engineers to test a design to see how it will perform in the real world. So Marty can use a model to test his design in a lab, before it is used in real airplanes. This process will ensure that Marty's deign is both effective and safe.

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
