Good Practice Physics Examples

HONORS PHYSICS CH. 14 WAVE PRACTICE PROBLEMS 1. The period of a drift is 0. 0300 seconds. It travels at a velocity of 10. 0 m/s. situate the frequency and the wavelength. 2. A wave having a wavelength of 4. 0 meters and an amplitude of 2. 5 meters travels a outstrip of 24 meters in 8. 0 seconds. Determine the frequency and the period of the wave. 3. While hiking through a canyon, Noah Formula lets out a scream. An echo (reflection of the scream tally a nearby canyon wall) is comprehend 0. 82 seconds afterwards the scream.The speed of the sound wave in look is 342 m/s. Calculate the distance from Noah to the nearby canyon wall. 4. Mac and drool be resting on top of the water near the end of the pool when Mac creates a surface wave. The wave travels the length of the pool and rear end in 25 seconds. The pool is 25 meters long. Determine the speed of the wave. 5. An automatic focus camera is able to focus on objects by riding habit of an ultrasonic sound wave. The camera send s out sound waves that reflect off distant objects and return to the camera.A sensor detects the time it takes for the waves to return and then determines the distance an object is from the camera. The camera lens then focuses at that distance. Now thats a smart camera In a subsequent life, you might birth to be a camera so try this problem for convention If a sound wave (speed = 340 m/s) returns to the camera 0. 150 seconds after leaving the camera, then how far away is the object? 6. Find the wavelength of a 680-Hz tone in air, where the wave speed is 340 m/s. 7. Imagine a hiker camping in the mountains.Just before going to sleep he yells, WAKE UP, and the sound echoes off the nearest mountain, returning 8 h later. How far away is that mountain? 8. Harriet is told by her doctor that her heart consecrate is 70. 0 beats per minute. If Harriets average blood flow in the aorta during systole is 1. 5 x 10 -2 m/s, what is the wavelength of the waves of blood in Harriets aorta, create d by her beating heart? 9. While flying to Tucson, Connies piece of paper experiences turbulence that causes the coffee in her cup to oscillate back and off 4 times each second.If the waves of coffee have a wavelength of 0. 1 m, what is the speed of a wave moving through the coffee? 10. Danielle is force her twin dextral on a swing that hangs from a steer branch by 2. 0-m-long ropes. With what frequency will Danielle have to push Dexter when he swings? 11. In California, Clay is surfing on a wave that propels him toward the beach with a speed of 5. 0 m/s. The wave crests are each 20. m apart. A. What is the frequency of the water wave? B. What is the period?
