Engineers create 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. What is the best step for the engineers to make next? A. Decide what profit margins they would like to see for this new technology 0 B. Test the new airplane in a wind tunnel test. O C. Build a new plane with this material. D. Design a new airplane with this new material.​

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
