On a standard 400-meter track, the 1000m race is exactly 2.5 laps, so it starts on the far 200-meter line, runs two full laps, and then finishes the final half lap to end at the standard finish line. On a 200-meter indoor track, the 1000m race is five full laps. What is a G...
Patch 949dd0104c49 (“powercap: restrict energy meter to root access”), in Linux kernel 5.10.0-rc4, changes the default permissions on these attributes such that only the system administrator (root account) can access these attributes.
000 watts, whereas kilowatt-hours (kWh) measures your energy usage – or to put simply the power consumed per hour. So let’s put this in a real-time perspective. 1 kWh would be used to run a 1000-watt appliance for an hour (assuming no efficiency loss). Or on a smaller scale, a...
What is the speed of a walking person in meters per seconds if the person travels 1000 meters in 20 minutes? (1,000 meters/20 minutes) x (1 minute/60 seconds) = 5/6 meter per second What is the average speed if someone walks 2km in 30 minutes? The average...
AC_powermeter_advanced.ino- This example also demonstrates a complete AC-power measurement application. It runs on interrupt basis for getting better stable readings. Voltage and current are both sampled at 3kHz. When the Arduino led is lit, the ADC clips (too high input peak voltage) or the...

A sample could be inserted, the desired wavelength of light dialed in, and the amount of absorption of that frequency measured with a simple meter. With relative ease and repeatability, it provided accurate absorption spectra in both the ultraviolet and visible regions of the spectrum. Tests were...
4. Sweden and France are now discovering that nuclear power that would be “too cheap to meter”, according to their government salesmen, is now indeed extremely expensive to mothball. Both have a black eye. Decommissioning cost ARE relevant for a radioactive plant. You simply can mothball any...
(There are some errors in this video. I didn't prepare for this video in advance at all. I also had a faulty electric meter at the time, that was reading low. My actual electric use is about 1/10th the national average, not 1/30th. My water use s about 1/4 the national average...
the shop, over the plug of the sensor near the tank or over the meter behind the instrument panel. The electrical plug above the sensor is by far most easy to reach. Connect it, wherever you can, parallel to the wires, shorting them out. The resistor would have to come with the ...
