Answer:
osmosis
Explanation:
osmosis is the movement of solvent materials through a semi permeable membrane into a region of solute concentration, therefore water moving through a membrane is an osmotic process.
We Know, P = m*v
Here, m = 30 Kg
v = 5 m/s
Substitute it into the expression,
P = 30*5 Kgm/s
P = 150 Kgm/s
So, your final answer is 150 Kg.m/s
Hope this helps!
