Answer:
d.solid to liquid cause they were once on a fixed and started to slide.liquid particles slide along a container so it is a solid to liquid
Answer:
I think d. is the answer I'm not conform
Answer:
wave speed= constant
frequency = increase
wavelength = decrease
Explanation:
Solution:
- The three basic parameters of a wave are speed, frequency and wavelength. These three parameters are related to each other by an expression:
v = f * λ
Where,
- v is the speed of the wave in m/s.
- f frequency of the wave in Hz.
- λ wavelength of the wave in m
- We are asked how would each of these parameter change if we move the hand up and down faster. The hand moves from a crest to trough faster than before and back again. We can see that the time between a cycle has decreased; hence, frequency f increases. Consequently, we can see that wave speed v remains constant - the medium of transfer of wave energy - remains same. Then from our relation above if we hold speed constant and increase f then the wavelength λ would have to decrease.
