Answer:
The salt molecules (Sodium ions and Chlorine ions) in the ocean water makes it a good conductor of electricity.
Explanation:
Conductivity<em> refers to the ability of an object to transmit electricity.</em> Transmitting electricity means allowing electricity to pass through the material. The best conductor of electricity is <u>"silver."</u> Other elements which are also good conductors are: <em>gold, aluminum, copper, etc. </em>Those which are poor in conducting electricity are called insulators. These include <em>glass, plastic, rubber, paper, styrofoam, etc. </em>
<u>Ocean water is considered a good conductor of electricity because it contains Sodium ions and Chlorine ions.</u> Remember that ions carry electrical charges, which could either be positive or negative. <u>The Sodium ion here is positively charged, while the Chlorine ion is negatively charged.</u> Being mixed with water makes it an electrolyte solution. When electricity travels, it needs to have two sources: a positive terminal and a negative terminal. This means that the Sodium ions will be attracted to the electricity's negative terminal, while the Chlorine ions will be attracted to the positive terminal. This will allow the electrons to flow through the medium, thus creating a circuit for electricity to pass through.
This is the reason why ocean water is a good conductor of electricity.
Hello!
By applying the third law of motion, your force and the wall's force are equal.
I hope this helps you! Have a great day!

Answer:
Fricción.
Explicación:
Caminando con otro compañero al mismo tiempo y al mismo ritmo, el movimiento se produce debido a la fricción del suelo y la suela de los zapatos porque la fricción es la fuerza que ayuda en el movimiento de los objetos de un lugar a otro. Si no hay fricción entre el suelo y la suela de los zapatos, no podemos dar un paso por lo que podemos decir que la fricción nos mueve hacia adelante.
Answer:
The force must increase
Explanation:
According to newton's second law "force is the product of mass and acceleration".
Force = mass x acceleration
Now, the mass of the sports car is lesser compared to that of the truck. Therefore, to take both automobiles to the same speed, enough force must be applied by the engine of the truck.
There must be an increase in the force in order to make both automobiles attain the same speed.
The electrostatic potential energy, U, of one point charge q at position d in the presence of an electric field E is defined as the negative of the work W done by the electrostatic force to bring it from the reference position d to that position
Thus, to double the electric potential energy U we need to reduce the distance of separation by half (1/2) because they are inversely proportion
