Answer:
Osmosis.
Explanation:
If there is a selectively permeable membrane which is separating two liquids of different osmolarity or solute concentration then the process by which the solvent will move from one solution to another so as to attain equilibrium is known as osmosis. The existence of a selectively permeable membrane is the basic difference between diffusion and osmosis. Osmosis is characterized by the presence of such membrane which allows the movement of solvent only and restricts the movement of solute. In contrast to this, in diffusion there is no such restriction on the movement of particles from a region of high concentration to a region of low concentration.
In view of above in the given example, the solvent i.e. water will tend to move from pure water side towards the 4% NaCl solution side and the movement will continue until the osmolarity becomes equal on both the sides.
An independent variable is something that will occur without something else happening. An example of an independent variable is when your income depends on the number of sales. In this situation, your income depends on how many sales you make, so therefore, the number of sales you make is the independent variable.
Answer:
185.1 m/s
Explanation:
The average speed of an object is a scalar quantity telling us how fast is the object moving over a certain distance.
This quantity is calculated as
where
d is the distance covered by the object
t is the time elapsed
v is the average speed
In this problem we have:
d = 1500.0 m is the distance covered by Ken
t = 8.1018 s is the time taken
Substituting into the formula, we find the average speed:
Answer:
I think the answer is chemical energy
Explanation:
When it gains an electrons is negatively charged so in this case I think it will be. -ion
