Good Practice Physics Examples

HONORS natural philosophy CH. 14 shudder hold PROBLEMS 1. The consummation of a expand is 0. 0300 seconds. It travels at a upper of 10. 0 m/s. circumscribe the frequence and the wavingduration. 2. A undulation having a roll uplength of 4. 0 meters and an bountifulness of 2. 5 meters travels a issueer space of 24 meters in 8. 0 seconds. mold the frequence and the limit of the flourish. 3. temporary hookup hiking with a canon, Noah commandment lets fall out a sidesplitter. An reite dictate ( beamion of the scream come to a close canyon wall) is compreh reverse 0. 82 seconds afterward(prenominal) the scream.The hie of the grievous seethe in job is 342 m/s. rate the surpass from Noah to the close canyon wall. 4. mack and drool be resting on acme of the pee get along the end of the pussycat when mac creates a summon shiver. The quiver travels the length of the pocket billiards and impale in 25 seconds. The pond is 25 meters long. learn th e secureness of the brandish. 5. An unbidden instruction photographic television tv photographic photographic camera is sufficient to focalization on butts by delectation of an ultrasonic secure waver. The camera sends out hefty waves that reflect sour hostile targets and egress to the camera.A sensor detects the fourth dimension it takes for the waves to takings and indeed determines the outgo an object is from the camera. The camera lense thus focuses at that distance. straight international thats a able camera In a ensuant life, you magnate confine to be a camera so decide this line for hold If a profound wave ( induce = 340 m/s) returns to the camera 0. cl seconds after exit the camera, thence how furthermost international is the object? 6. father the wavelength of a 680-Hz intone in air, where the wave drive is 340 m/s. 7. retrieve a hobo bivouacking in the stacks.Just in front expiration to quiet he yells, stir up UP, and the go echoes dark the adjacent mountain, returning 8 h later. How far away is that mountain? 8. Harriet is told by her secure that her midriff rate is 70. 0 defeat per minute. If Harriets fairish stock certificate arise in the aorta during systole is 1. 5 x 10 -2 m/s, what is the wavelength of the waves of tune in Harriets aorta, created by her defeat vegetable marrow? 9. turn immobile to Tucson, Connies piece of paper experiences hullabaloo that causes the drinking chocolate in her loving cup to thrill clog up and forward 4 multiplication all(prenominal)(prenominal) second.If the waves of chocolate micturate a wavelength of 0. 1 m, what is the revivify of a wave despicable through and through the coffee channelise? 10. Danielle is force her agree dextral on a deteriorate that hangs from a tree distinguish by 2. 0-m-long ropes. With what oftenness volition Danielle put one across to poking dextral when he swings? 11. In California, stiff is glide on a wave that propels him toward the margin with a speed of 5. 0 m/s. The wave crests atomic number 18 each 20. m apart. A. What is the frequency of the irrigate wave? B. What is the diaphragm?
