Air Force Common Admission Test (AFCAT) is conducted in two stages. The first stage consists of a written test and the second stage involves a testing process. Call letters to report to Dehradun, Mysuru, Gandhinagar, Varanasi, or Guwahati (any one of the selection boards) are sent to qualified candidates of testing process.
The WAPS Promotion Score Calculator is used by enlisted airmen to estimate the minimum test score for promotion to the next enlisted rank.Users enter the promotion year, enlisted grade, their "Total Active Federal Military Service Date", date of their last promotion, EPRs, military decorations, and an estimate of the "Air Force Promotion Cutoff Score" in the Web page's form.
The Drude model of electrical conduction was proposed in 1900 [1] [2] by Paul Drude to explain the transport properties of electrons in materials (especially metals). Basically, Ohm's law was well established and stated that the current J and voltage V driving the current are related to the resistance R of the material. The inverse of the ...
In the first case the force is continuously applied to the car by a person, while in the second case the force is delivered in a short impulse. Contact forces are often decomposed into orthogonal components, one perpendicular to the surface(s) in contact called the normal force, and one parallel to the surface(s) in contact, called the friction ...
The NDA Exam is administered by the Union Public Service Commission (UPSC), which is a constitutional body responsible for recruiting personnel for various government services and posts. The UPSC ensures the fair and transparent conduct of the examination process, including the release of notifications, application acceptance, examination ...
This mechanism is found very commonly in everyday life, including central heating and air conditioning and in many other machines. Forced convection is often encountered by engineers designing or analyzing heat exchangers, pipe flow, and flow over a plate at a different temperature than the stream (the case of a shuttle wing during re-entry, for example).
Energy: the conduction of heat in a solid material is an example of heat diffusion. Momentum: the drag experienced by a rain drop as it falls in the atmosphere is an example of momentum diffusion (the rain drop loses momentum to the surrounding air through viscous stresses and decelerates).
Ballistic conduction is typically observed in quasi-1D structures, such as carbon nanotubes or silicon nanowires, because of extreme size quantization effects in these materials. Ballistic conduction is not limited to electrons (or holes) but can also apply to phonons. It is theoretically possible for ballistic conduction to be extended to ...
