Which statements apply to transverse waves? Check all that apply.

The question is incomplete as it does not have the options which are:

The waves have a trough.

Particles move only small distances.

particles travel the length of the wave, moving in an up-and-down motion.

The waves have a crest.

The energy is transferred perpendicular to the direction of the wave motion.

Explanation:

Transverse waves are the waves which can be characterised easily by their oscillation in a perpendicular direction to the path of the wave propagation.

The particle follows the wave nature and moves only to a small distance like ripples in the water and these waves possess the trough, the lower part and the crest the upper part.

These waves can be observed in ripples of the water, in a string of the guitar while playing and the electromagnetic waves.

Thus, the selected options are correct.

  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
