<span>The contraction of muscles in the stomach walls is called peristalsis.
Peristalsis works to physically break down food and move it forward.
Hope this works! :)</span>
<span>Density is a physical
property of a substance that represents the mass of that substance per unit
volume. It is a property that can be used to describe a substance. We calculate as follows:
Density = 182.48 g - 115.25 g / 0.100 pint ( 0.47 L / 1 pint ) = 67.23 g/0.047L
Density =1430.43 g/L </span>
Answer: A. Transverse
Explanation:
Sound is a mechanical transverse wave, it travels faster in solids than in liquids or gases. This is because the speed of the mechanical waves is determined by a relationship between the elastic properties of the medium in which they are propagated and the mass per unit volume of the medium.
In addition, the speed of sound varies with changes in the temperature of the medium. This is because an increase in temperature means that the frequency of interactions between the particles that transport the vibration increases, hence this increase in activity increases the speed.
Hence:
<h3>Sounds travels in a <u>transverse</u> wave</h3>
Sound and light are similar in that both are forms of energy that travel in waves. They both have properties of wavelength, freqency and amplitude. ... Sound is a form of mechanical energy caused by vibrations of matter. Light is electromagnetic energy caused by interacting electric and magnetic fields.
Explanation:
Gravitational potential energy = mgh = (5)(9.81)(7) = 343.35J.
