Prayagraj Chheoki Junction railway station, formerly Allahabad Chheoki railway station [1] (station code: PCOI), [2] is one of the major railways stations (besides Prayagraj Junction railway station) located in Prayagraj district. Chheoki is at a distance of 10 km from Prayagraj Junction on the Howrah–Delhi main line.
Snap, [6] or jounce, [2] is the fourth derivative of the position vector with respect to time, or the rate of change of the jerk with respect to time. [4] Equivalently, it is the second derivative of acceleration or the third derivative of velocity, and is defined by any of the following equivalent expressions: = ȷ = = =.
The opening of the Curzon Bridge, across the Ganges, in 1902, linked Prayagraj to regions north of or beyond the Ganges. [5] The Varanasi–Prayagraj City (Rambagh) line was constructed as a metre-gauge line by the Bengal and North Western Railway between 1899 and 1913. It was converted to broad gauge in 1993–94.
Jerk (also known as jolt) is the rate of change of an object's acceleration over time. It is a vector quantity (having both magnitude and direction). Jerk is most commonly denoted by the symbol j and expressed in m/s 3 ( SI units ) or standard gravities per second ( g 0 /s).
The resistance distance between vertices and is proportional to the commute time, of a random walk between and . The commute time is the expected number of steps in a random walk that starts at u {\displaystyle u} , visits v {\displaystyle v} , and returns to u {\displaystyle u} .
The North Central Railway (abbreviated NCR) is one of the 19 railway zones in India.The largest railway station in NCR is Kanpur Central.It is headquartered at Prayagraj and comprises three divisions: Prayagraj, Jhansi, and Agra of the erstwhile Northern Railway, Jhansi division of the erstwhile Central Railway, and new Agra division.
The Planck time, denoted t P, is defined as: = = This is the time required for light to travel a distance of 1 Planck length in vacuum, which is a time interval of approximately 5.39 × 10 −44 s. No current physical theory can describe timescales shorter than the Planck time, such as the earliest events after the Big Bang. [ 30 ]
The entire Howrah–Delhi line, via Howrah–Bardhaman chord and Grand Chord is classified as a "Group A" line which can take speeds up to 160 km/h. [25] However actual maximum permissible speed on Pandit Deen Dayal Upadhyaya Junction–Kanpur section is 130 km/h for Rajdhani, Shatabdi, Duronto, GR and a few Express trains.
