Question

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.

Answer 1

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

Step-by-step 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.

Answer 2

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