The speed of sound in human tissue is about 1600 m/s. If an ultrasound pulse takes 1.5 x 10--s to travel through a tissue, what is the thickness of the tissue in mm?

The thickness of the tissue is : 2.4 x 10⁷ mm

Explanation:

The general formula for speed is the distance travelled divided by the time taken.

In this case,

Speed = 1600 m/s  speed of sound in human tissue

Time = 1.5 * 10 seconds time of taken for the ultrasound pulse to go through a certain thickness of a tissues

The thickness of the tissue here is the distance as per the speed formula, hence;

Tissue thickness = Speed of sound * time taken by ultrasound pulse

Tissue thickness= 1600 * 1.5*10 =24000 m

1 m= 1000 mm

24000m = 24000*1000 mm

= 2.4 x 10⁷ mm

this is poiselle's equation from fluid mechanic in physics. mech eng

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )
