If you mean an inflatable boat - sure
the car works when you add salt water in the car. the magnesium reacts to the salt water.
Boat motors work by converting fuel into mechanical energy, which is used to turn a propeller. The propeller then pushes water backwards, creating a force that propels the boat forward.
By loosing some of the water and replacing it with unsalted water you will need to work out how much water will have to be thrown out to get the correct salt levels.
The usual reason for salt in a pool is for chlorination. Epsom salt won't work with salt/chlorine generators. BUT, you can add epsom salt to your water.
an egg can work move or grow because it can go in salt water and when you put salt water it will go higher
Salt water works because electricity needs a conduit to get electrons from one place to another. Salt is a molecule that is able to do this when it is dissolved in water.
yes
it removes salt water by the salt water absorbing by the sun . And the sun absorbs the water and then bring it to the clouds and make rain, the rain goes in the water and its saltwater yet again
No because it will take away some of the salt that you have rinsed out your throat with and it won't work as affectively as it should.
Rudders work by changing the direction of the water flow around the boat, which in turn changes the boat's direction. When the rudder is turned, it creates a force that pushes the stern of the boat in the opposite direction, causing the boat to turn in the desired direction.
A pontoon boat would be a light boat that is shallow to take in the water. Of course you could also get an inflatable boat, and that would work just as well.
A paddle boat uses oars called paddles. Instead of a engine and steering wheel to move about on the water.
