Could you please help me with these waves and sound questions? Please could you show me the steps? I would really appreciate it.Thanks in advance and have an excellent day.
1.) Harriet is told by her doctor that her heart rate is 70.0 beat per minute. If Harriet's average blood flow in the aorta during systole is 1.5*10^-2 m/s, what is the wavelength of the wave of
blood in Harriet's aorta, created by her beating heart?
2.) Dogs are able to hear much higher frequencies than hymans are capable of detecting. for this reason, dog whistles that are inaudible to the human ear can be heard easily by
a dog. If a dog whistle has a frequency of 3.0 * 10^4 Hz, what is the wavelength of the sound emitted?
3.) while flying to Tucson, Connie's plane experiences turbulence that causes the coffee in her cup to oscillate back and forth 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?
4.) at a country music festival in New Hampshire, the Oak Ridge Boys are playing at the end of a crowded 184-m field when Ronny Fairchild hits a note on the keyboard that has a
frequency of 400. Hz. a.) how many full wavelengths are there between the stage and the last row of the crowd? b.) how much delay is there between the time a note is played and the
time it is heard in the last row?
Please could you help me with these Waves and Sounds problems?
