A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echo patterns are shown on the screen of an ultrasound machine, forming a picture of body tissues called a sonogram. Also called ultrasonography.

An ultrasound device is used to measure?

"An ultrasound device is used to measure blood ﬂow in an artery. An ultrasonic transducer in the probe emits inaudible sound at f0 = 25 kHz. The sound enters the artery and reﬂects oﬀ moving blood cells. When the reﬂected sound returns to the probe it is combined with the emitted sound and fed to a speaker. The speaker produces audible sound at the beat frequency. The technician can listen to the speaker to better position the probe. If the technician holds the probe at an angle such that the blood is ﬂowing directly away from the probe the speaker produces sound at fb = 200 Hz. Using this information and the fact that the speed of sound in blood is v = 1500 m/s, what is the velocity of the blood ﬂow? (Answer 6.0 m/s) i am supet stuck! help please!"

If it's consequently, can which make all our feelings in addition to morals worthless? Sexual love, don't you think just merely a number of compounds being released from the mind? Are certainly not only then do we purely bots? Your thoughts as well as feelings are generally cycle responses regarding some kind of stimuli? In the event many of us certainly are nothing yet neurological machines, then isn't really lifestyle really ineffective? Just how do us pay dividends in the event each and every thought, experience, memory for example. is actually reducable for an electric transmission let go in between two nerves along with taken with a chemic natural chemical? Is all that awareness is definitely, this kind of digesting? Just about all delight, significance, purpose is nothing yet an unwanted effect connected with a number of reaction, and that we are like a robot, powerlessly following precisely how the mental faculties are hard-wired. Or maybe shall we be more than a equipment? Are we more than merely elementary chemical like allergic reactions? Shall we be held not just something of your long chain of toys? Shall we be merely slaves to the personal brain, genetics, and also surroundings? Could there be truly objective and significance? Furthermore, if many of us simply natural equipment, so what is the point involving ethic and ethics? The nice that we do is nothing merely a different sort of stimuli that sets of a chain impulse inside our encephalon. Why then with regards to with regards to other's health and fitness? You could start to bargain when you're able to, perform when you might, as well as disregard each of the moral unique codes in the event that we've been just a bunch of chemical compounds?"
