What diagnostic technique creates images of deep body structures by redcording the echoes of pulses of sound waves that are above the range of human hearing?
Ultrasound imaging, also known as sonography, is the diagnostic technique that creates images of deep body structures by recording the echoes of pulses of sound waves above the range of human hearing.
How magnets are used in speakers?
Coils of copper wire are wrapped around the magnets. The music in your radio is converted to electrical pulses that move thru those copper wires wrapped around those magnets. The direction and strength of those electrical pulses causes them to have a magnetic reaction with the flowing electricity. This magnetic reaction is connected to a moving mechanism that is attached to your speaker cone. The way the cone moves back and forth from this coil reacting to the magnet recreates the sound coming from the radio station So the magnet is just to turn your speaker into a big electromagnet that moves like a solenoid in response to changing electrical impulses that duplicate the sound generated. The magnet has a constant field, but the coil of wire is the electromagnet but it reacts to permanent magnet. Usually the bigger the permanent magnet the bigger the sound the speaker can produce because it can generate stronger pulses from that solenoid coil that reacts to the magnet under electrical impulses
Is an imaging technique that records and uses the echoes of pulses of sound waves above the range of human hearing?
The imaging technique you are referring to is likely ultrasound imaging. Ultrasound uses high-frequency sound waves to create images of organs and structures inside the body. It is commonly used in medical diagnostics for its ability to provide real-time images without exposing the patient to harmful radiation.
How did NASA get images of Venus through its dense cloud coverage?
NASA spacecrafts such as Magellan use radar imaging to penetrate Venus' dense cloud coverage. Radar signals can pass through clouds and bounce off Venus' surface, allowing spacecrafts to create detailed images despite the thick clouds.
What kind of pulses did Venus' topography has been mapped from space and earth?
Venus' topography has been mapped using radar pulses from space to penetrate its thick cloud cover, revealing surface features like mountains and craters. On Earth, topography mapping has been done using various methods such as LiDAR, satellite imagery, and ground-based surveys to create detailed 3D models of the terrain.
When Tim pushes the wire between the poles of the magnet the galvanometer registers a pulse When he lifts the wire another pulse is registered How do the pulses differ?
The pulses differ because the two pulses are in opposite directions.
Why does a telephone use a magnet?
There is a magnet in the both the microphone and speaker. They change differences in air-pressure (in the microphone) to electrical pulses, and in the speaker, they cause the cone to vibrate - creating sound.
A series of evenly timed pulses create a wave that can be described as a wave?
A series of evenly timed pulses create a wave with a constant frequency, also known as a periodic wave. The repetition rate of the pulses determines the wave's frequency, while the amplitude of the pulses determines the wave's intensity or strength. This type of wave can be observed in various phenomena such as sound waves or electromagnetic waves.

A series of evenly timed pulses create a wave that can be described as a?
A series of evenly timed pulses create a waveform known as a square wave, which has a sudden transition between high and low states. This waveform is commonly used in digital electronics for encoding binary signals.

What is the weight of a AA battery?
200 tonnes. the electro magnetic pulses create a zero space weight to which is impossible to feel.
What are the advantages of pulses?
pulses? like in the pulses you heart makes us hear?
How do speakers and headphones work?
Speakers use pulses of electricity to activate a small electromagnet that surrounds another magnet. it has a plastic covering, so as to mimic the vibration of our vocal chords and make noise.
