Since Uber's launch, several other companies have copied its business model, a trend that has come to be referred to as Uberification. Uber was founded as UberCab by Travis Kalanick and Garrett Camp in 2009 and the app was released the following June. Beginning in 2012, Uber expanded internationally.In 2014, it experimented with carpooling features and made other updates.n some cities, if the Uber car is travelling at a speed greater than 11 mph (18 km/h), the price is calculated on a distance basis, otherwise, the price is calculated on a time basis. At the end of a ride, the complete fare is automatically billed to the customer's credit card.
1 How are they formed? a hydrogen bond is formed when a charged part of a molecule having polar covalent bonds forms an electrostatic (charge, as in positive attracted to negative) interaction with a substance of opposite charge. Molecules that have nonpolar covalent bonds donot form hydrogen bonds.  Strenght.
The hydrogen atoms in an H2 molecule are therefore held together (or bonded) by the sharing of a pair of electrons and this bond is the strongest when the distance between the two nuclei is about 0.074 nm.
