In eq. (10.1) in the lab manual, the constant rhoυ is 41.1 gm-cm^{-2} −2 sec^{-1} −1  in air. a piece of paper has a mass per unit area of approximately 7x10^{-3} −3 gm/cm^{2} 2 . if the frequency is 3.6 khz, what does theory predict for the ratio of the transmitted amplitude to the incident amplitude of the sound wave? (a sound wave is a pressure wave.)

the moving of the box is a result of centripetal force. think of that  as a car or a truck in this case creates a turn, the force of friction performing upon the turned wheels of the car runs centripetal force obligatory for circular motion for the things inside it.

earth's neighboring galaxy, the andromeda galaxy, is a distance of 2.54×107 light-years from earth. if the lifetime of a human is taken to be 70.0 years, a spaceship would need to achieve some minimum speed min to deliver a living human being to this galaxy.
