Physics Wallah, or "PW", was founded in 2016 as a YouTube channel hosted by Alakh Pandey, an educator hailing from Prayagraj, Uttar Pradesh.The channel was initially focused on teaching the physics curriculum for the Joint Entrance Examinations (JEE), a popular entrance examination in India. [2]
The Pratt & Whitney Canada PW800 is a series of turbofan engines in the 10,000–20,000 lbf (44–89 kN) thrust class, manufactured by Pratt & Whitney Canada.Intended for the regional jet and business jet market, the gear-less PW800 shares a common core with the larger, geared PW1000G.
The PW530 has a single stage fan, driven by a 2-stage LP turbine, supercharging a 2A/1CF axial-centrifugal HP compressor, driven by a single stage HP turbine. Although similar in configuration, the PW535 has a booster stage, mounted on the LP shaft behind the fan, to increase overall pressure ratio and core flow.
The PW 300 series has been developed in partnership with MTU who are responsible for the low pressure turbine. The first variant, the PW305A, has the following configuration and was designed with a core flexible enough for engines with take-off thrusts from 20 kN to 31 kN (4,500 to 7,000 lb): a single-stage fan driven by a three-stage low pressure turbine, supercharging a four-stage axial ...
Historically, a crude form of PWM has been used to play back PCM digital sound on the PC speaker, which is driven by only two voltage levels, typically 0 V and 5 V. By carefully timing the duration of the pulses, and by relying on the speaker's physical filtering properties (limited frequency response, self-inductance, etc.) it was possible to ...
Uttara Padwar is from Madhya Pradesh where she leads a "Prayas Shiksha Samiti". This group works with Baigas, Gondi people and the Abhujhmarias. These tribal people suffer from poverty, malnutrition and disease and her group strives to alleviate it. [1]
LibreOffice (/ ˈ l iː b r ə /) [11] is a free and open-source office productivity software suite, a project of The Document Foundation (TDF). It was forked in 2010 from OpenOffice.org, an open-sourced version of the earlier StarOffice.
In practice, only a PC Client protection profile was created for TPM 1.2. Protection profiles for PDA and cellular were intended to be defined, [5] but were never published. A complete specification consists of a platform-specific specification which references a common four-part TPM 2.0 library.
