Ocean engineers could combat the corrosive ocean water by investing a new material which does not corrode in the ocean. Ocean engineer are prepared people to make a build systems that monitor an control coastal environment.
For preventing corrosion requirement of elimination or suppression using two principal methods, cathodic protection and coatings. They are normally, cathodic protection system are used in conjunction with coating systems.
Main objective or aim of the cathodic protection is to suppress the electrochemical reaction taking place. These engineers and naval architects work along the coast- both offshore and land.Sometimes these engineers work on oil rigs, where they oversee the repair of system that they may have design.

Answer:
107.3g
Explanation:Density = Mass/Volume
There are two methods either by taking the above formula and inserting the values or by using Mass = Denstiy*Volume
Here I have showed you both the ways:
1st
As Desnity is 21.46g/cm^3
Volume = 5cm^3
Let m be mass
21.46g/cm^3=m/5cm^3
Cross multiplication takes place here
21.46*5=m
107.3 =m
Therefore, mass of platinum = 107.3g
2nd
Mass = Denstiy*Volume
Density = 21.46g/cm^3
Volume = 5cm^3
m=21.46g/cm^3* 5g/cm^3
m= 107.3g
Answer:
Answer: hydrosphere is related to the water,when hydrosphere gets polluted it inadvertent and deliberate discharge of petroleum, and thermal pollution also are seriously affecting the quality of hydrosphere.
Condensation is the change of gas to water (eg, water vapor to liquid water).
precipitation is gas to liquid (rain).
