Answer: Una onda de sonido es un ejemplo de onda mecánica. Las ondas sonoras son incapaces de viajar a través del vacío. Las ondas furtivas, las ondas del agua, las ondas de los estadios y las ondas para saltar la cuerda son otros ejemplos de ondas mecánicas; cada uno requiere algún medio para existir.
English Translation: A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum. Slinky waves, water waves, stadium waves, and jump rope waves are other examples of mechanical waves; each requires some medium in order to exist.

.40 as a fraction is 4/10 or 2/5
the 4 is in the tenths place, so put it over a 10 to make it a fraction.
then, simplify the fraction by dividing the numerator and denominator by 2, and you get 2/5
At a divergent boundary, plates move away from each other, allowing magma to fill up the cracks in between the plates to form new land. This creates rift valleys and mid ocean ridges.
(1) The difference in pressure between the ends of the pipe is 611 kPa.
(2) The Reynold's number for this torpedo is 1.2 x 10⁷.
(3) The flow of water around the torpedo is turbulent.
<h3>Difference in pressure between the ends of the pipe</h3>
The difference in pressure is calculated by applying Poiseuille formula.
where;
- Q is flow rate
- r is radius of the pipe
- L is length of the pipe
- η is viscosity
- ΔP is change in pressure
<h3>Reynold's number for the torpedo</h3>
<h3>Laminar or turbulent flow </h3>
- A flow is considered laminar if the Reynolds number is up to 2300.
- A flow is considered turbulent if the Reynolds number is greater than 3500.
The calculated Reynold's number (1.2 x 10⁷) is greater than 3500. Thus, the flow is turbulent.
