Ununennium, also known as eka-francium or element 119, is a hypothetical chemical element; it has symbol Uue and atomic number 119. Ununennium and Uue are the temporary systematic IUPAC name and symbol respectively, which are used until the element has been discovered, confirmed, and a permanent name is decided upon.
Fairchild C-119 Flying Boxcar. C-119C, AF Ser. No. 51-2640, 781st Troop Carrier Squadron / 465th Troop Carrier Wing. The Fairchild C-119 Flying Boxcar (Navy and Marine Corps designation R4Q) was an American military transport aircraft developed from the World War II -era Fairchild C-82 Packet, designed to carry cargo, personnel, litter patients ...
U.S. Route 119 enters West Virginia from Kentucky as unsigned ADHS Corridor G, a four-lane limited-access highway stretching from Williamson to Charleston. The earliest segment of Corridor G to open was in 1972 and was finished in 1997. Formerly, US 119 was a typical two-lane mountain highway. Old US 119 now comprises all or parts of US 52, WV ...
The Liouville function λ(n) is 1 if Ω(n) is even, and is -1 if Ω(n) is odd. The Möbius function μ(n) is 0 if n is not square-free. Otherwise μ(n) is 1 if Ω(n) is even, and is −1 if Ω(n) is odd. A sphenic number has Ω(n) = 3 and is square-free (so it is the product of 3 distinct
Power-to-weight ratio is a measurement of actual performance of any engine or power source. It is also used as a measurement of performance of a vehicle as a whole, with the engine's power output being divided by the weight (or mass) of the vehicle, to give a metric that is independent of the vehicle's size. Power-to-weight is often quoted by ...
United States Army Air Forces. Produced. 1944–1948. Number built. 223. Developed into. Fairchild C-119 Flying Boxcar. The C-82 Packet is a twin-engine, twin-boom cargo aircraft designed and built by Fairchild Aircraft. It was used briefly by the United States Army Air Forces and the successor United States Air Force following World War II.
In the context of electromagnetics and optics, the frequency is some function ω(k) of the wave number, so in general, the phase velocity and the group velocity depend on specific medium and frequency. The ratio between the speed of light c and the phase velocity v p is known as the refractive index, n = c / v p = ck / ω.
Commonly, a binomial coefficient is indexed by a pair of integers n ≥ k ≥ 0 and is written It is the coefficient of the xk term in the polynomial expansion of the binomial power (1 + x)n; this coefficient can be computed by the multiplicative formula. which using factorial notation can be compactly expressed as.
