0. Give an example of how an organism can use surface tension.<br><br><br>​
Lady_Fox [76]

Answer:

In case of plants surface tension help to support the transpiration pull.

Explanation:

Surface tension is a force that hold the molecules in the surface to minimize the surface area.

   During evaporation of excess amount of water from the stomata of leaves of plants by transpiration a surface tension is generated.

   The generated surface tension helps to maintain the water column within the xylem tissue by the absorption of water from the soil by the roots.

A. Match the term with its definition. (1 point)
Assoli18 [71]

Taking into account the definition of wavelength, frecuency and propagation speed:

  • Frequency: The number of waves passing a point in 1 second.
  • Wavelength: The distance between two adjacent wave peaks.
  • Velocity:  The direction and speed at which a wave is traveling.

The equation that illustrates the relationship between wave velocity, frequency, and wavelength is v = f×λ.

<h3>Wavelength</h3>

Wavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. It is expressed in units of length (m).

<h3>Frequency</h3>

On the other side, frequency is the number of vibrations that occur in a unit of time. Its unit is s⁻¹ or hertz (Hz).

<h3>Propagation speed or velocity</h3>

Finally, the propagation speed is the speed with which the wave propagates in the medium, that is, it is the magnitude that measures the speed at which the wave disturbance propagates along its displacement.

The propagation speed relate the wavelength (λ) and the frequency (f) inversely proportional using the following equation:

v = f×λ

All electromagnetic waves propagate in a vacuum at a constant speed of 2,998 x 10⁸ m / s, the speed of light.

Therefore, the previous expression establishes an inversely proportional relationship between the frequency and the wavelength: The higher the frequency, the lower the wavelength and when the frequency is lower, the greater the wavelength.

<h3>Summary</h3>

In summary, the definition of frequency, wavelength and velocity are:

  • Frequency: The number of waves passing a point in 1 second.
  • Wavelength: The distance between two adjacent wave peaks.
  • Velocity:  The direction and speed at which a wave is traveling.

Finally, the equation that illustrates the relationship between wave velocity, frequency, and wavelength is v = f×λ.

Key words how atoms work?
pantera1 [17]
Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom(which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. Most of an atom is empty space.

I hope this helps you! :D

In the following reaction, what is the effect of adding more NO2 to the starting reaction mixture?
Mars2501 [29]

Answer:

It would increase the final quantity of products

Explanation:

According to the Le- Chatelier principle,

At equilibrium state when stress is applied to the system, the system will behave in such a way to nullify the stress.

The equilibrium can be disturb,

By changing the concentration

By changing the volume

By changing the pressure

By changing the temperature

Consider the following chemical reaction.

Chemical reaction:

2NO₂ ⇄ N₂O₄

In this reaction the equilibrium is disturb by increasing the concentration of reactant.

When the concentration of reactant is increased the system will proceed in forward direction in order to regain the equilibrium. Because when reactant concentration is high it means reaction is not on equilibrium state. As the concentration of NO₂ increased the reaction proceed in forward direction to regain the equilibrium state and more product is formed.

a block of wood has a density of 0.95 g/cm3. will it float or sink when placed on a liquid with a density of 0.88 g/mL? explain
vesna_86 [32]
Since 1mL=1cm^3 the wood would sink due to it being more dense. I.e. 0.95>0.88
