Answer from: solisemily62

Answer;

High temperature and pressure

Explanation;Nuclear fusion in stars and supernovae is the primary process by which new natural elements are created. Nuclear fusion occurs in presence of very high temperature and high pressure, which one of the common characteristics of many stars.High temperature gives hydrogen atoms enough energy to overcome the electrical repulsion between the protons. Fusion requires temperatures about 100 million Kelvin. High pressure squeezes the hydrogen atoms together. For example the sun uses its mass and the force of gravity to squeeze hydrogen atoms together in its core.

Answer from: wbrandi118

The most important requirement for a star to initiate the hydrogen fusion is very huge pressure and a very high temperature in the core of the star.

Explanation:

The star is the ultimate source of energy for several planets rotating around it making it a system. The star is very large in size and mass as compared to the planets.

The planets are considered to be formed as the broken part of the star itself. Therefore, they are smaller than the star. The energy produced in a star is due to the fusion reaction between the hydrogen atoms.

The nuclear reaction that involves the fusion of the two hydrogen atoms require a very high pressure and a huge temperature in the core of the star to initiate the nuclear reaction.

Such high pressure on the star is only generated by the huge size of the star. This is the reason that the star is always larger in size as compared to the planets.

Thus, The most important requirement for a star to initiate the hydrogen fusion is very huge pressure and a very high temperature in the core of the star.

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ
