Beat-to-beat variability of the QT interval (QTV) has been used as a marker of repolarization lability and sympathetic activation. The aim of this study was to establish ECG sampling rate requirements for reliable QT interval variability measurement. We measured QTV in high resolution simulated (...
The natural frequency of the circuit shows in Fig. is View Solution The resonant frequency of an L - C circuit is View Solution A series LCR circuit withR=22Ω,L=1.5HandC=40μFis connected to a variable frequency 220 V ac supply. When the frequency of the supply equals the natural fr...
Submit What is the frequency of a 20 m radiowave? Aa.15MHz Bb.12MHz Cc.1200 KHz Dd.25 MHzSubmit What is the natural frequency of LC circuit ? What is the reactance of this circuit at this frequency ? View Solution What is the frequency of infrasonic sound ? View Solution What is ...
When the frequency induced into the system due to an external unbalanced force, equals the natural frequency of the material, then continuous vibration of the body takes place and if this prevails, the body will fail disastrously in this condition. This condition is known as resonance and the ...
These natural waveguides occur when the Sun is rising or setting, which makes sunrise and sunset good times to pick up VLF emissions. 当日出或日落的时候,这些波导就会产生,这样日出日落时就成了接收VLF排放的好时机。 Now, there are a few different sounds that you can hear on a VLF receiver, ...
“All we do for all children here is to give them visual, auditory and touchable stimulation with increased frequency, intensity and duration, in recognition of the orderly way in which the brain grows,” says Doman. “The result was that by 1960 we had hundreds of severely brain-injured ...
after being kidnapped, finds herself isolated and living in the wilderness of eastern europe during world war ii. in an unexpected turn of events, she is suddenly thrust into teaching a group of jewish people who escap...
When sound reflects from a wall, the standing wave is formed. The natural frequencies of vibrations, which are determined by the speed and the length of a cylindrical tube, in the tube open at both ends are different from that at only one...
Natural frequencies are different fromforced frequencies, which occur by applying force to an object at a specific rate. The forced frequency can occur at a frequency that is the same as or different from the natural frequency. When the forced frequency is not equal to the natural frequency, t...
