Answer:
44.1 m
Explanation:
<u>Given:</u>
= speed of sound in air = 343 m/s
= speed of sound in the rod = 
= times interval between the hearing the sound twice = 0.12 s
<u>Assumptions:</u>
= length of the rod
= time taken by the sound to travel through the rod
= time taken by the sound to travel to through air to the same point = 
We know that the distance traveled by the sound in a particular medium is equal to the product of the speed of sound in that medium and the time taken.
For traveling sound through the rod, we have
..........eqn(1)
For traveling sound through the air to the women ear for traveling the same distance, we have

Hence, the length of the rod is 44.1 m.
Answer:
Dencidad = 600 kg/m³
Explanation:
Dados los siguientes datos;
Lado del cubo = 10 cm a metros = 10/100 = 0,1 m
Masa = 0,6 kg
Para encontrar la densidad;
En primer lugar, determinaríamos el volumen del cubo usando la fórmula;
Volumen del cubo = lados³
Volumen del cubo = 0.1³
Volumen del cubo = 0.001 m³
Ahora, podemos encontrar la densidad usando la fórmula;
Dencidad = masa/volumen
Dencidad = 0,6/0,001
Dencidad = 600 kg/m³
