Answer:
C. is correct option.
Explanation:
Speed of sound in a particular temperature depends upon bulk modulus and density of material.
It is directly proportional to bulk modulus of material and inversely proportional to the density.
As we move from air to aluminium, their density increase which decrease speed of sound in them. But as we move down to their bulk modulus also increases and increase in that bulk modulus is too much comparable to their increase in density.(You can google their density and bulk modulus respectively).
So, at the end their bulk modulus factor overcome the sound that decreased due to density.
And overall sound increases .
Therefore the speed of sound is higher in solids than in liquids.
Answer:
One country could be gaining more benefit than the other.
Answer:
Up And Down
Explanation:
In this case, the particles of the medium move parallel to the direction that the pulse moves. This type of wave is a longitudinal wave. Longitudinal waves are always characterized by particle motion being parallel to wave motion.
