4. Name the solution of a salt of the plating metal?

5. What does the friction due to fluid called as? answer for this question plspls​

Answer 1

Answer:

2. cation carry positive charge.

Answer 2

Answer:

Ans 1. Frequency of a wave determines its pitch.

Pitch is a characteristic of a sound that depend on the frequency received by a human ear.

Ans2. The cation is an ion that carries a positive charge, causing it to migrate to the cathode in a electrolysis. It has more protons than electrons, resulting in the positive charge.

Ans 3.Sonar uses sound waves to 'see' in the water.

NOAA scientists primarily use sonar to develop nautical charts, locate underwater hazards to navigation, search for and map objects on the seafloor such as shipwrecks, and map the seafloor itself.

Ans 4.Generally, one of the electrodes is made from the metal we're trying to plate and the electrolyte is a solution of a salt of the same metal. ... Copper ions (which are positively charged) are attracted to the negatively charged brass electrode and slowly deposit on it—producing a thin later of copper plate.

Ans 5. the friction due to fluid called as fluid.
