Interstellar space has an average temperature of about 10 K , and an average density of hydrogen atoms of about one hydrogen ato

Bas_tet [7]

Answer:

$2.2508\times 10^{19} m$ meter the mean free path of hydrogen atoms in interstellar space.Explanation:

The mean free path equation is given as:

$\lambda =\frac{1}{\sqrt{2}\pi d^2 n}$

Where"

d = diameter of hydrogen atom in meters

n = number of molecules per unit volume

We are given: d = 100 pm = $100\times 10^{-12}= 10^{-10} m$

$n = 1 m^{-3}$

$\lambda =\frac{1}{\sqrt{2}\pi (10^{-10} m)^2\times 1 m^{-3}}$

$\lambda =2.2508\times 10^{19} m$

$2.2508\times 10^{19} m$ meter the mean free path of hydrogen atoms in interstellar space.

<h2>Active Transport </h2>

Explanation:

A cell uses energy for the movement of substances against a concentration gradient or an electrochemical gradient that maintains a balanced concentration of ions and molecules in living cells.
This transport of substances is known as Active transport mechanisms which are the basic function of the cell membranes.
The energy used is in the form of ATP.
Active transport occurs when there is a difference in the concentration of particles on both sides.
