Why is defibrillation not effective when there is a total absence of venticular electrical activity in the heart?
When there is no electrical activity in the heart (asystole), the AED won't start the heart as drugs are required to start the heart. The AED will only re-set the heart from abnormal electrical activity (such as V-Tach or V-Fib).
What makes an atomatic door open atomatically?
An automatic door has a controller, an electrical sensor and a motor. The sensor detects an approach to the door either by the interruption of a laser beam or by a pressure pad. This is set up to send a signal to the controller which triggers the motor on the door which moves the door to the open position. The motor then closes the door after a set time period unless the sensor is re-triggered in that time.
What is the effect of heat on solid liquid and gas?
Heat cause excitation of electrons and molecular vibration. More heat is the more molecular vibration and at the certain point when the energy in molecular vibration exceed the bonding energy, the molecules or atom then set free from the solid bonding and move freely. In absent of atmospheric pressure, the solid would become gas but with the pressure or presence of other gases, the matter may be mobile yet held together in liquid state. The liquid, with more heat, the energy from molecular excitation would set such liquid to become gas.
How many vacation days do chefs get?
How much holiday you get is normally set out in your contract of employment. ... For example, if you work two days a week you would be entitled to 11.2 days' ... You need to calculate how many hours a week you work on average over the whole ... you would be on holiday and so not working to accrue annual leave.
Different types of instruction set architecture?
RISC - Reduced Instruction Set Computer CISC - Comples Instruction Set Computer
Why tv produced electrical energy?
It doesn't. If you mean the TV set at your home, it USES electrical energy.
When you turn on a television set what do you change?
Mechanical energy into electrical energy
What kind of energy does a TV set changes?
A TV set converts electrical energy into light and sound energy to display images and emit sound. It does this through the process of converting electrical signals into visual and auditory output.
What is the energy transfer in a TV set?
In a TV set, electrical energy is transformed into light energy and sound energy. Electrical energy is used to power the screen to produce images and the speakers to produce sound. This transfer of energy allows us to see and hear the content displayed on the TV screen.
What is the energy conversion of a television set?
Electrical-sound-light-heat
What kind of energy is involved in turning on a TV set?
Electrical energy is involved in turning on a TV set. When you press the power button, it activates the flow of electricity through the TV, powering up its components like the display screen and speakers.
Does a motor have electrical energy in it?
An electric motor need to be supplied electricity to operate. It can be made to generate electricity if turned by an outside force when set up correctly.
Does a radio converts from electrical energy to sound energy?
yes. because you have to plug in the radio which is electrical and then when you turn on the radio it produces sound. even if it's a battery powered radio, the battery stores energy in the form of chemical energy, but delivers it as electrical energy, so even in that radio, the radio is converting electrical energy to sound energy when you turn on the radio. What about an old-fashioned "crystal set" that has no battery and doesn't plug into the wall ? Even that one converts electrical energy into sound. The only electrical energy it ever gets is what it picks out of the air that got transmitted from the radio station. That's very very little energy, which is why the sound from a crystal set is always so weak.
Which set of items listed can produce mechanical energy from electrical energy?
battery,wire,iron
Explain the operation of an alternator?
Turning mechanical energy into electrical energy The alternator works by turning mechanical energy into electrical energy. When your engine is on, it powers a drive belt that rests on a pulley attached to the alternator. The pulley turns the alternator's rotor shaft, which spins a set of magnets around a coil.
What should my water heater be set at to ensure optimal performance and energy efficiency?
To ensure optimal performance and energy efficiency, set your water heater temperature to 120 degrees Fahrenheit. This temperature is recommended to prevent scalding and reduce energy consumption.
Which are the best intermittent energy sources?
The best type of intermittent energy is pumped energy. Pumped energy is when water is pumped up into a dam during a period of low energy consumption (generally at night) and is stored there until a period of high energy usage. When the electricity is required, the water is released and the power fed into the electrical supply. This makes pumped energy controlled unlike other forms such as tidal power where the energy is available twice daily at set times only.
