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,

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

c, liquids evaporate, creating a gas

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
