What is the job of an insulator?
Thermal insulator, prevent heat loss and protect human or machine from heat. Electrical insulator, prevent human and machine from electrical hazard and prevent short circuit that would damage electrical appliance.
Is a human hair a conductor?
it is a fair conductor.
What energy does the human body use while running?
We use potential energy that's converted to kinetic energy
What are subsonic signals?
Subsonic signals are sounds or vibrations that have a frequency lower than that which may be heard by the human ear as a discernable tone. Vibrations lower than 30 Hz (30 cycles per second) are considered subsonic.
What are 3 good electrical conductors?
Three conductors of electricity are metals, water and the human body.
How fast does electrical signals travel through the human body?
350 ft/s
What device converts sound waves to electric current?
Microphones will convert sound waves into electrical signals. An ear (i..e human ear) will also convert sound waves into electrical signals.
What energy change take place in your eye?
The process by which light is detected by the human eye and converted to an image is a serious of energy changes. Light is the first energy which causes chemical reactions. These reactions are then changed to electrical energy signals which are sent to the brains through the optical nerve.
Why body is good conductor?
The human body is 61.8% water. Water conducts electrical conductor as a result. Mind you, the human body is capable of generating 11,000 watt hours of electrical energy in a typical lifetime. Not to mention that your eitire body runs on electrical signals to and from your brain. Gotta move that kidney data somehow.
How are electrical signals carried through the body?
Your nerves do. Your brain sends electrical signals through your nerves to your muscles to make you move. Signals from the far ends travel through nerves back to your brain, so you can see, hear, smell, taste, and feel.
Can the human body transmit outside the body?
It depends on what you mean by "transmit". Our nerves and muscles use electrical signals. These signals can be detected outside the body. The biochemical processes in each cell uses energy. This energy can be detected outside the body as heat.
The order in which light reaches the lens of a human eye?
When light enters the eye, it first passes through the cornea, which is the clear outer covering of the eye. It then travels through the pupil, which is the opening in the center of the iris. Next, it reaches the lens, which focuses the light onto the retina at the back of the eye, where it is converted into electrical signals that can be interpreted by the brain.
What is audio singnal?
An audio signal is a representation of sound, typically as an electrical voltage. Audio signals have frequencies in the audio frequency range of roughly 20 to 20,000 Hz (the limits of human hearing).
Why is it very difficult to understand how the human mind works?
because brains have unknown electrical signals & radio waves, and they don't all work the same, and God had to leave the reward of that knowledge for the here~after
The human eye is sensitive to?
light stimuli which is converted into electrical impulse (current)and then is transmitted to the occipital area of the brain . The image seen by the right eye is transmitted to the left hemisphere and viceversa.
How is voice communications converted to digital signals?
The human voice is an analogue signal because the frequency of the sound varies in the sound waves as well as their amplitude that gives the power. Analog signal is defined as a signal that has a continuously varying amplitude or frequency. Human speech, and everything else a human hear, is in analog form.
What hormone signals satiety in the human body?
It isCholecystokinin
