Tsunami waves are caused by earthquakes in the ocean floor. as the waves approach the shore, they usually grow in height. when this occurs, which aspect of the wave is changing?

Amplitude of wave is changing

Explanation:

As we know that amplitude is defined as the displacement of medium particle about its mean position.

This amplitude also help to evaluate the energy of wave. It is given by

Now as we know that wave reaches to the shore which means energy start adding up to the molecules of shore

So here energy of molecules is increasing which directly shows that amplitude of wave is increasing so here we can say that due to increase in the amplitude of the wave the height of the wave is increasing and in terms of energy we can say that energy carried by the wave is converting into potential energy due to which height is increasing

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz
