The amplitude of a wave is related to the energy of a wave. How could you demonstrate this relationship between energy and wave

People holding the slinky supply the energy to make the patterns. To make pattern 1, people have to shake the slinky back and forth at a certain speed. To make pattern 2, the slinky has to be moved back and forth faster (higher frequency). To make pattern 4, the people need to move the slinky back and forth much faster. It is much easier to make pattern 1 than pattern 4 because it takes less energy. This illustrates the relationship between frequency and energy – the higher the frequency, the higher the energy.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
