Engineers find a new metal that is stronger than steel but much lighter. this

material is also significantly cheaper than what is currently used for most

aircraft, available in large quantities, and easy to manufacture. the engineers

ore excited because this new metal will lower companies cots of buying and

operating airplanes. what is the best step for the engineers to make next?

a. begin marketing a plane constructed from this metal,

o

b. conduct a flight test for an airplane made from this metal,

c. decide whether or not to paint the new aircraft

o

d. begin to design an airplane using this metal,

D

Explanation:

I think they would design a airplane with this new metal first because they have to find the right balance for this new type of metal. They can't just sell a airplane with a new metal that has a different weight immediately they need to test it and design it first.

D

Explanation:

The answer is D, because while it is important to market the material and make sure people are interested in buying, they first need to try and design a plane using this material. There is no use selling a plane made out of this material, if a plane cannot be built.

the mass of the cathode increases because ions from the solution get reduced to atoms and become part of the cathode.
