The Battle of Britain was an air-to-air combat between the RAF and the Luftwaffe to show who's better in the air or not. The Blitz was the strategic bombing campaign against British cites by the German Luftwaffe bombers. It was likely that around 20,000 Londoners died during the bombings. Views.
The program SSH (Secure Shell) provides an encrypted channel for logging into another computer over a network, executing commands on a remote computer, and moving files from one computer to another.SSH provides strong host-to-host and user authentication as well as secure encrypted communications over the Internet.SSH2 is a more secure, efficient, and portable version of SSH that includes SFTP, which is functionally similar to FTP, but is SSH2 encrypted.SH provides strong host-to-host and user authentication as well as secure encrypted communications over the Internet.

The SN2 reaction is a type of reaction mechanism that is common in organic chemistry. In this mechanism, one bond is broken and one bond is formed synchronously, i.e., in one step.S N 2 is a kind of nucleophilic substitution reaction mechanism.Since two reacting species are involved in the slow (rate determining) step, this leads to the term s ubstitution n ucleophilic (bi-molecular) or SN2, the other major kind is SN1.his is because the nucleophile attacks from the back of the substrate, thus breaking the carbon-leaving group bond and forming the carbon-nucleophile bond. Therefore, to maximise the rate of the S N 2 reaction, the back of the substrate must be as unhindered as possible.
