Which statement best describes how a wave would move differently through a pot of boiling water than the steam created from it?

The wave would move faster through the water than through the steam. The wave would move slower through the water than through the steam. The wave would move the same speed through the water and the steam. The wave would move through the water and steam at the same speed, but decrease in speed at the transition point.

Answer:

The wave would move faster through the water than through the steam

Explanation:

A mechanical wave is a wave that is transmitted through the oscillations of the particles in a medium. The closer the particles in the medium are, the more efficient the transmission of the wave is (because the collisions between the particles are more frequent), and so the faster the wave.

For this reason, mechanical waves travel faster in liquids (such as water) than in gases (such as the steam): because particles in liquids are closer together than in gases, where they are more spread apart. Therefore, the correct choice is

The wave would move faster through the water than through the steam

Alenkasestr [34]

Answer:

v = 1.30 m/s

Explanation:

given,

mass hung = 0.35 Kg

spring stretched when load is hanged  (x)= 0.13 m

now,

weight of the mass attached = Kx

             m g = k x

             0.35 x 9.8 = k x 0.13

                k = 26.38 N/m

now, using conservation of energy

 \dfrac{1}{2}mv^2 = \dfrac{1}{2}kx'^2

 v = \sqrt{\dfrac{kx'^2}{m}}

 v = \sqrt{\dfrac{26.38 \times 0.15^2}{0.35}}

 v = \sqrt{1.6958}

    v = 1.30 m/s

Klio2033 [76]

Answer:

Autotrophs

Explanation:

When you go down a food chain continuing to ask "what does it eat?" the last living thing that you will land upon is an autotroph.

Autotrophs are the primary producers as they (photoautotrophs) use the energy either from the sun to prepare  there food by the process of photosynthesis or, more rarely, obtain chemical energy through oxidation (chemoautotrophs) to make organic substances from inorganic ones.

Autotrophs get consumed by the primary consumers in the food chain.
