#1 The Correct Answer is D
<span>D) The Distance Traveled by The Wave During One Full Cycle.
Ex. frequency, wavelength, amplitude and wave speed. Amplitude is measured in metres (m). The greater the amplitude of a wave then the more energy it is carrying. The wavelength, λ, of a wave is the distance from any point on one wave to the same point on the next wave along.
(The symbol is a Greek letter, 'lambda'.)
#2 The Correct Answer is B
</span><span>B) Police Siren
Ex.Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Slinky waves, water waves, stadium waves, and jump rope waves are other examples of mechanical waves; each requires some medium in order to exist. </span>

Explanation:
All that you need to know here is that in order for a given sample of water to contain exactly 1 mole of water, it must contain 6.022
⋅
10
23 molecules of water.
This is known as Avogadro's constant and essentially acts as the definition of a mole. If you have 6.022
⋅
10
23 molecules of water, then you can say for a fact that you have 1 mole of water.
Answer:
A hypothesis is something you can test a theory is just a thought that you have.
Chemical change
