The first number is the total number of seconds the system has been up. The second number is how much of that time the machine has spent idle, in seconds. [16] On multi-core systems (and some Linux versions) the second number is the sum of the idle time accumulated by each CPU. [17]
If this implied uncertainty is considered as too overestimated, then more proper significant digits in the unit conversion result may be 2 0.32 cm ≈ 20. cm with the implied uncertainty of ± 0.5 cm. Another exception of applying the above rounding guideline is to multiply a number by an integer, such as 1.234 × 9.
The doubling time is the time it takes for a population to double in size/value. It is applied to population growth, inflation, resource extraction, consumption of goods, compound interest, the volume of malignant tumours, and many other things that tend to grow over time.
The metre per second is the unit of both speed (a scalar quantity) and velocity (a vector quantity, which has direction and magnitude) in the International System of Units (SI), equal to the speed of a body covering a distance of one metre in a time of one second.
After CO 2 injected into underground geologic formations, there is a risk of nearby shallow groundwater becoming contaminated. [26]: 242 Contamination can occur either from movement of the CO 2 into groundwater or from movement of displaced brine. [26]: 242 Careful site selection and long-term monitoring are necessary to mitigate this risk.
The sievert (symbol: Sv [note 1]) is a unit in the International System of Units (SI) intended to represent the stochastic health risk of ionizing radiation, which is defined as the probability of causing radiation-induced cancer and genetic damage.
An elite athlete's heart recorded during a maximum effort workout maintaining over 180 bpm for 10 minutes. The maximum heart rate (HR max ) is the age-related highest number of beats per minute of the heart when reaching a point of exhaustion [ 28 ] [ 29 ] without severe problems through exercise stress. [ 30 ]
Presently the ecliptic latitude is 43.5° South, but it has decreased by a fraction of a degree since Ptolemy's time due to proper motion.) In Ptolemy's time, Alpha Centauri was visible from Alexandria, Egypt, at 31° N, but, due to precession, its declination is now –60° 51′ South, and it can no longer be seen at that latitude.
