The Standard hydrogen electrode (abbreviated SHE), is a redox electrode which forms the basis of the thermodynamic scale of oxidation-reduction potentials. Its absolute electrode potential is estimated to be 4.44 ± 0.02 V at 25 °C, but to form a basis for comparison with all other electrode reactions, hydrogen's standard electrode potential (E0) is declared to be zero volts only at 298.

The speed of all the electromagnetic radiation are always   same   and   equal   to   the numerical value 3 x 10^8m/sec.

Bronze is the mixture of is a mixture of copper and tin. The composition is copper is 88% and tin is 12%.

The Progressive Movement:

Today, you hear the term ''progressive'' discussed a lot in politics, but progressivism is not a new concept. It was first used to describe policies and interventions of the late 19th to early 20th century, by reformers who felt the need for societal changes.

The first Progressives felt called to action in response to the conditions of poverty, inequality, and corruption that were pervasive during the 19th century.
