The device consisted of a 9-inch-long (23 cm) monopole antenna (quarter-wave for 330 megahertz [MHz] frequencies, but it was also able to act as half-wave [at 660 MHz] or full-wave [at 1320 MHz]; the accounts differ. Given the radio technology of the time, the frequency of 330 MHz is most likely, equivalent to a wavelength of 91 cm). [4]
Charging them for fifteen minutes in the case gives three hours of listening time. [16] The charging case provides 24 hours of total usage time. [ 17 ] During a complete dismantling, each AirPod was found to contain a 93 milliwatt hour battery in its stem, while the charging case contains a 1.52 watt hour or 398 mAh at 3.81 V battery.
Jealousy isn't a good look — unless you're a tiny little dog learning that your mama is pregnant for the first time. Video of the pup in question, Willow, coming to terms with her parents' good ...
Tach timer. The tach (ometer) timer is an instrument used in aviation to accumulate the total number of revolutions performed by the engine. The unit of measure is equivalent to the number of hours of running at a certain, specific reference speed of rotation. If the reference speed of rotation is 2400 RPM then the timer runs in real time when ...
The true history of pigeons is one of thousands of years of careful cultivation by humans, followed by nearly utter abandonments in the last century. We think of pigeons as a nuisance today, but ...
The temperature was already above 80 degrees and rising. The work of maintaining the public water supply in a heat wave is crucial. But it needs to be done as safely as possible. That means ...
Time. Watch, a time measurement device. In the past, a common time measuring instrument was the sundial. Today, the usual measuring instruments for time are clocks and watches. For highly accurate measurement of time an atomic clock is used. Stopwatches are also used to measure time in some sports.
Clock rate. Microprocessor clock speed measures the number of pulses per second generated by an oscillator that sets the tempo for the processor. It is measured in hertz (pulses per second). In computing, the clock rate or clock speed typically refers to the frequency at which the clock generator of a processor can generate pulses, which are ...
