Rank the speeds of sound through these materials, from greatest to least:a. Airb. Steelc. Water
s344n2d4d5 [400]

Ranking order of speed of sound is; Steel >Water > Air.

Speed of sound in normal air is 340 m/s, in water the speed is 1,430 m/s and in steel the speed is 5920 m/s.

<h3>What is speed of sound?</h3>

The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. The speed of sound in an ideal gas depends only on its temperature and composition. The speed of sound in mathematical notation is conventionally represented by 'c'. The speed of sound is variable and depends on the properties of the substance through which the wave is travelling.

The density of aluminium is 2.7 g/cm3. Find the mass in grams of a bar of aluminum measuring 2.7 cm by 1.2 cm by 14.3 cm.
Fofino [41]

Answer:125.0964g

Density = mass/volume

Density = 2.7 gcm-3

Volume=2.7*1.2*14.3=46.332

Mass=?

Mass= density* volume

= 2.7× 46.332=125.0964g
