Waves are a repeating pattern of motion that transfers energy from place to place without overall displacement of matter. Light and sound are wavelike
phenomena. By understanding wave properties and the interactions of
electromagnetic radiation with matter, scientists and engineers can design
systems that?
Transfer information
Transfer heat
Store information
All of the above

If you were to drop a rock from a tall building, assuming that it had not yet hit the ground, and neglecting air resistance. what is its vertical displacement (in m) after 6 s?

Aquantity of gas has a volume of 1.5 m3 and an absolute pressure of 95 kpa. when the gas is compressed to a volume of 0.5 m3, what is the new absolute pressure of the gas? (assume that there’s no change in temperature.)

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 are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
