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.

   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.

Describe the radial velocity curve. What is its shape? What is its amplitude? What is the orbital period?
lutik1710 [3]

Answer:

The radial velocity curve describes how fast a star is moving in its orbit around a center of mass ( m )

Curve amplitude : This is the maximum value of the radial velocity curve

Radial velocity shape ; The shape of Radial velocity curve is parabolic in nature

Orbital period : Orbital period is the time taken by the star  to make one complete rotation in its orbit

Explanation:

The radial velocity curve describes how fast a star is moving in its orbit around a center of mass ( m ) while Curve amplitude  is the maximum value of the radial velocity curve also The shape of Radial velocity curve is parabolic in nature. and  Orbital period is the time taken by the star  to make one complete rotation in its orbit
