Answer:

The ranking of the waves from the lowest energy wave to the highest energy wave is 1 → 4 → 2 → 3.

Explanation:

  • Amplitude is the highest vibrated position of a wave measured from the equilibrium position.
  • So the least amplitude for wave 1 is the least energy representation.
  • Similarly distance from midpoint to crest or trough is also the measure for the energy level of wave. Crest and trough, both are the maximum amplitude condition of the wave.
  • So 12 cm being the highest represents the highest energy level i.e wave 3.

Explanation:

1kg in household measurement is equal to 35.274 ounces. 35.274*9=317.466 ounces.

1kg is also equal to 2.205 lbs. 9*2.205=19.8416

9 kg is also equal to 9000 grams, but grams are not a part of the household measurement system

a) 9000 grams. b) 9000 ounces. c) 19.8 ounces. d) 19.8 pounds.

This leaves us with 19.8 lbs
