Answer:The process of purifying sea water into fresh water is called Desalination, which essentially means removing the salt from water.
There are two main industrial size process for desalination, one is thermal desalination which is distillation using heat and the other is with Reverse Osmosis or RO using water pressure through membranes.
In some places they’re doing inverse osmosis, which needs lots and lots of energy, maybe being in a sunny place.
Evaporation is a also a good method for removing salt from sea water but that is used only in low consumption of water.Israel is currently using the desalination process successfully and there is a plant that I read about near San Diego, CA.
Here some methods are help to removing salt from sea water
Turning Salt water into Drinking water using Solar power
The MIT team's this new desalination technology "electrodialysis" is comparatively less expensive.
Graphene Sieve turns Seawater into Drinking water
A new research shows graphene can filter common salts from water to make it safe to drink.The new findings could lead to affordable desalination technology.
Graphene-oxide membranes have attracted considerable attention as promising candidates for new filtration technologies. Now the much sought-after development of making membranes capable of sieving common salts has been achieved.
New research demonstrates the real-world potential of providing clean drinking water for millions of people who struggle to access adequate clean water sources.
Explanation: Thanks and good luck.
Titanium's high quality to weight proportion and corrosion protection at room and hoisted temperature makes it appealing for use in elite applications. High cost of titanium is the key purpose behind not utilizing it in traveler autos. The cost of large scale manufacturing of the parts would drive the last items cost fundamentally.
Answer:
Petroleum
Explanation:
Because Petroleum reservoirs can be depleted but something like wind energy wind will always be there
I think everytime they swim away, the water pushes the enemy back, which makes the octopus go faster. Every action has an equal and opposite reaction. Hope this helps.
Answer: 4.8 s
Explanation:
We have the following data:
the mass of the raft
the force applied by Sawyer
the raft's final speed
the raft's initial speed (assuming it starts from rest)
We have to find the time 
Well, according to Newton's second law of motion we have:
(1)
Where 
is the acceleration, which can be expressed as:
(2)
Substituting (2) in (1):
(3)
Where 
Isolating from (3):
(4)
Finally:
