If the resolving power of a human eye is 0.125 mm, and the resolving power of a certain electron microscope is 0.84 nm. how many times better is the resolving power of this electron microscope than the human eye?

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

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?
