What property makes ocean water a good conductor of electricity
Lostsunrise [7]

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.

Identify each statement that describes a benefit of the scientific method. (Select all choices that apply)
Alecsey [184]

The statements that describe a benefit of the scientific method are as follows:

  • It gives scientists a standardized way to approach a problem.
  • It reduces bias and judgment from personal experiences.
  • It gives scientists a common vocabulary for sharing information.

Thus, the correct options are B, C, and D.

<h3>What is the Scientific method?</h3>

The scientific method may be defined as a strategy of research in which a problem is recognized, relevant data is collected, a conjecture is composed of this data, and the assumption is empirically tested to determine the outcome of particular research.

The scientific method never explains or provides an answer to any question immediately because it consists of a scripted format with certain parameters.

The scientific method uses the identical vocabulary for sharing information with one another in particular terminology.

Therefore, it is well described above.

An 80kg parachutist jumps out of an airplane. Neglecting air friction, how fast will he be going after a 10 second free fall?

If he is jumping you are adding force which means that you will be falling twice as fast
