Consider an airplane weighing 2 lb in a level cruise flight. Denoting Drag by D, Lift by L, and velocity (in feet per second) by V, it’s Drag-to-Lift relationship is given by 2 4 2 2 2.3769 10 23.9808 L D V V       . Compute and plot the thrust required to maintain the cruise flight for a velocity range of 10 to 100 ft/sec

Ifeel like lily and ledbetter had a fair pay act just because it was necessary especially at those times

Caused conformity rates to go down. apex ; )

One answer could be erosion

Sounds propagates through some kind of medium. usually it's air, but it goes just as well through solid objects like walls, windows etc. a soundwave will compress the (air)molecules in front of it, and if this increased density wave hits your ears, you register it as sound. solid objects like walls are a lot denser than air, this means that they will damp a wave, but also carry it easier.
