Yes,
It is because the speed of sound in solids is very higher than speed of sound in gasses(air). As the molecules present in the solids are very close to each other and transfer disturbance easily and quickly to other molecules. In gasses molecules are farther apart and require more time to travel. Hence speed of sound in gasses are lower than in solids.
Second reason '
AS velocity = V = square root [ elastic modulus /density ]
Gasses are more compressible and hence have smaller elastic modulus so have lower speed .
Because you're getting closer to other planets?
Answer:
velocity of this in the direction of the Earth is 6.4 × m/s
Explanation:
given data
wavelength = 121.6 nm
wavelength = 124.2 nm
solution
we get here first change in wavelength that is
= 124.2 nm - 121.6 nm ...............1
= 2.6 nm
we get here velocity of direction of the Earth that is express as
............2
put here value we get v
v =
v = 6.4 × m/s
Answer:
liquid pressure increases with depth. so, when the divers go deep, the pressure on them increses.
