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

moisture is lackin, and organic acids are scarce.
