What has to happen to sound wave before they can be transmitted by radiowaves?
The sound signal must firstly be changed into an electrical signal.
When electrical signal reaches end of nerve fiber a chemical what is secreted?
When the action potential (electrochemical signal) reaches the end of the nerve, calcium channels open, causing synaptic vesicles containing neurotransmitters to bind with the neuronal membrane. When this happens, the neurotransmitters are released into the synaptic cleft (process is called exocytosis). Once in the synaptic cleft, they can bind with postsynaptic neuron or muscle cell receptors.
How many planets Earth signal reaches?
All of them in our solar system, plus all others within a distance of about 100 to 120 light years from us.
When traveling under 45 mph you must signal how many feet before turn?
100
What travels from your brain to your skeletal muscle cells when you move?
When you decide to move, an electrical signal called an action potential is generated in your brain. This signal travels along your neurons and reaches the skeletal muscle cells via motor neurons. At the neuromuscular junction, a chemical called acetylcholine is released, which stimulates the muscle fibers to contract and initiate movement.
Are drivers in Indiana required to signal before turning?
I haven't read a driver's manual for years, but yes, as far as I know drivers in Indiana are required to signal before turning.
On the freeway you are required to have your signal on for feet before changing lanes?
100 feet
On the freeway how many seconds are you required to signal before changing lanes?
7 seconds
Within how many feet before changing lanes on the freeway are you required to have your signal on?
100 feet
What effect will increasing the required transmission distance have on transmitting the signal clearly?
Increasing the required transmission distance of a signal will have a negative effect on the clearness of the signal. As the source is moved farther away from the receiver, a weaker signal will be present.
Does a iPod get internet connect anywhere?
Anywhere there is a wifi signal you have the password for. 3G models can get internet anywhere their carrier's cell signal reaches.
What equipment is required to be on at trailer?
signal lights
Why is modulation necessary before multiplexing?
modulation means transmitting the signal which is to be transmitted along with the carrier wave, then at the receiver it is separated from the carrier and demodulated. So modulation is needed so as to transmit the signal over long distances with higher accuracy. Hence it is required before multiplexing.
When signals come into the soma from the many dendrites they are added together. When the sum of these signals reaches a critical point a signal is fired down the axon. When it reaches the end of the?
threshold
Is there a minimum pulse width required for the interrupt signal?
no
Why current limiting resistor is required?
to keep the signal awy from the dc limit ,, to ban the clipping of the signal
How does a signal cross from the axon of the neuron to the receiving cell?
When the electrical signal reaches the end of an axon, neurotransmitters are released. They travel across the synapse. Once they reach the receiving cell, they create a new electrical signal.
