Time of useful consciousness ... 6–8 seconds of consciousness is expected. [2] Medical analysis and variations ... (22,000 ft; 6,700 m) 10 minutes
The foot per second (plural feet per second) is a unit of both speed (scalar) and velocity (vector quantity, which includes direction). [1] It expresses the distance in feet (ft) traveled or displaced, divided by the time in seconds (s). [2] The corresponding unit in the International System of Units (SI) is the meter per second.
One quadrillionth of a second. Pulse time on fastest lasers. svedberg: 10 −13 s: Time unit used for sedimentation rates (usually of proteins). picosecond: 10 −12 s: One trillionth of a second. nanosecond: 10 −9 s: One billionth of a second. Time for molecules to fluoresce. shake: 10 −8 s: 10 nanoseconds, also a casual term for a short ...
The foot per second squared (plural feet per second squared) is a unit of acceleration. [1] It expresses change in velocity expressed in units of feet per second (ft/s) divided by time in seconds (s) (or the distance in feet (ft) traveled or displaced, divided by the time in seconds (s) squared).
Estimated top speed of the Juno spacecraft (mass ~3600 kg) relative to Earth before insertion into Jupiter's orbit — second fastest human-made technical object. [27] 10 5: 100,000: 360,000: 224,000 0.0003: Dust particles in dust accelerators can exceed this speed. [28] 140,000: 540,000: 313,170 0.00047: Approaching velocity of Messier 98 to ...
The beard-second is a unit of length inspired by the light-year, but applicable to extremely short distances such as those in integrated circuits. It is the length an average beard grows in one second. Kemp Bennett Kolb defines the distance as exactly 100 angstroms (10 nanometres), [8] as does Nordling and Österman's Physics Handbook. [9]
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. More simply, the speed of sound is how fast vibrations travel. At 20 °C (68 °F), the speed of sound in air, is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.91 s or one mile in 4.69 s.
A verbal fluency test is a kind of psychological test in which a participant is asked to produce as many words as possible from a category in a given time (usually 60 seconds). This category can be semantic , including objects such as animals or fruits, or phonemic , including words beginning with a specified letter, such as p , for example. [ 1 ]
