Answer:

3. It is a passive process in which molecules move from a region of higher concentration to a region of lower concentration.

Explanation:

<em>Diffusion can be defined as the movement of solute or gaseous molecules from the region in which they have higher concentration to the regions in which they have lower concentration until they become evenly distributed across the two regions. </em>

<em>Diffusion is a passive process, that is, it requires no energy.</em>

Option 3 is the correct option.

Answer:

It is a passive process in which molecules move from a region of higher concentration to a region of lower concentration

Explanation:

Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. It is an important process for living things.

A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across a space

How can a vector have a component value equal to zero and also have a non zero magnitude
lina2011 [118]
The vector's magnitude is the square root of (one component squared) + (the other component squred). The magnitude is non-zero if one component or the other is zero, but not if they both are.

A merry-go-round is rotating at constant angular speed. Two children are riding the merry-go-round: Ana is riding at point A and
marysya [2.9K]

Answer:

bobby has a greater magnitude of velocity because because when angular speed is constant linear velocity is proportional to radius of the circular path

B. They both have same magnitude of angular velocity since the angular speed of the merrygoround is constant

C. Also they both have the same tangential acceleration because the angular speed is constant and tangential is zero for both of them

D. Centripetal acceleration of Bobby is greater

E.they both have the same angular acceleration because angular Speed I constant so angular acceleration is zero for both

A planet has two small satellites in circular orbits around the planet. the first satellite has a period 18.0 hours and an orbit
puteri [66]
The two satellites orbit around the same planet, so we can use Kepler's third law, which states that the ratio between the cube of the radius of the orbit and the orbital period is constant for the two satellites:
\frac{r_1^3}{T_1^2}= \frac{r_2^3}{T_2^2}
where
r_1 is the orbital radius of the first satellite
r_2 is the orbital radius of the second satellite
T_1 is the orbital period of the first satellite
T_2 is the orbital period of the second satellite

If we use the data of the problem and we re-arrange the equation, we can calculate the orbital period of the second satellite:
T_2 =  \sqrt{T_1^2 ( \frac{r_2}{r_1} )^3} = \sqrt{(18.0 h)^2 ( \frac{3\cdot 10^7 m}{2 \cdot 10^7 m} )^3}  = 33.1 h

A charged particle creates a(n) _____________field. Once this particle is in motion, this creates a(n) ____________ field.
Fittoniya [83]
A charged particle has an electrostatic field surrounding it.

When the particle is in motion, the moving charge is an
electric current, and that has a magnetic field around it.
