What is the chemical formula for carpet cleaner?
the chemical formula is a sented powder that has a static charge that cling to dirt and the suction from the vacumm pulls up the powder and the dirt leaving a pleasent sent
Why you use liquid nitrogen in eds detector?
The ED spectrometer is comprised of a liquid nitrogen (LN2) dewar, Si crystal, and preamplifier. The special Si crystal is mounted at the end of the detector located closest to the specimen. When X-rays strike the Si crystal very small signals are produced. These signals are amplified in the detector and sent on to the analysis electronics in the computer for further processing. The crystal is cooled by a cold finger, an extension of the LN2 dewar. Liquid nitrogen cools and therefore stabilizes the electronic properties of the crystal, improving the measurements of minute X-ray signals.
When the body becomes dehydrated a chemical signal is sent that causes nephrons in the kidneys to absorb more water and excrete more salts. This is an example of a?
a heat stroke -for gradpoint users :D
What is reverse osmosis system to purify water?
A R.O. machine contains a filter membrane that water is forced through. It mixes with a caustic chemical in a flocking process. Dirt is suspended. When reverse pressure is applied only the purified water is sent along to be used.
Why optical fiber is slowly replacing copper cables in telecommunications?
Copper wire passes computer communications through the use of modulated carrier waves. RF energy is susceptible to resistance which reduces the signal over distance according to the Rho value of the copper wire. The longer the wire the higher the resistance the less signal is received at the other end. Secondly, being an RF signal, copper wire is susceptible to receiving signals from other sources which can cause interference though inter-modulation products caused by phase sum and difference between competing signals. Thirdly, RF signals are subject to standing waves which are caused by mismatches between feeders. This mismatch can prevent the signal from leaving the feeder (Copper wire) which in turn can prevent the signal from being received at the other end and cause the transmitter amplifier to become stressed and fail. Finally, copper wire is limited in the speed of the signal which can be transmitted. Fibre optical cable With multi-frequency fibre cables multiple signals can be sent down one cable at one time. Dependent on the purity for the fibre cable there is very little optical resistance runs of over 20km can be easily achieved. There is no transmission frequency limit to light. There is no standing wave problem. There is no interference problem from external sources. Fibre bundles carry more signals that the equivalent copper wire bundle in less physical space.
How is information sent between Earth and spacecraft?
Using exactly the same technology that the dispatcher uses to send a taxi to your house ...radio communication.
How does the genie work?
The game genie works like a patch which overlays the signals being sent between the cartridge and the NES.
After your ears convert sound waves into electrical signals where are the signals sent for interpretation?
The brain
What is the role of an input and an output?
In computing,input and output refers to the communication between an information processing system like computer system. Inputs are the signals received by the system and outputs are the signals sent from it.
How does the game genie work?
The game genie works like a patch which overlays the signals being sent between the cartridge and the NES.
What did the telstar do?
Telstar sent television signals across the ocean.
Signals from the neurons of which sense are NOT sent to the cortex by the thalamus?
Smell
What was used to broadcast from the moon during the Apollo 11 mission?
The LM had an antenna array that could beam signals to Earth. When the astronauts were out on EVA, their suits had radios which beamed signals to the LM, which in turn sent the signals to Earth. The LM acted as relay between the Earth and the suit radios.
How are signals sent from the brain to the rest of the body?
They are sent through your nervous system by electric pulses from your brain
Electrical or chemical signals may control the movement of what across cell membranes?
Electrical or chemical signals may control the movement of ions across cell membranes. Ions are electrically charged particles that play crucial roles in various cellular processes. Electrical signals, such as action potentials, can trigger the opening or closing of ion channels to allow the movement of specific ions. Chemical signals, such as neurotransmitters, can also bind to receptors on the cell membrane to initiate a cascade of events that influence ion movement.
What feeds your muscles so that they can contract?
Your body produces a source of energy from food. It is called ATP. This is what your muscles use to contract. The signals are sent through a simple structure. The electronic signals from your brain travel through a gap in between your muscle and your nerves.
Spinal nerves carry what kind of information?
The spinal cord handles electrical signals sent between the brain and the rest of the body.
