Which statement might be correct based on dimensional analysis?

a. the height of the transamerica pyramid is 332 m2.
b. the time duration of a fortnight is 66 m/s.
c. the speed of the train is 9.8 m/s2

none

Explanation:

a. the unit of height does not carry a square( m^2 is unit of area)

b. time cannot be in m/s. it is unit of speed

c. m/s^2 are the units of acceleration

As a result, sound waves travel faster in solids than in liquids, and faster in liquids than in gasses. While the density of a medium also affects the speed of sound, the elastic properties have a greater influence on the wave speed. The density of a medium is the second factor that affects the speed of sound
