How are vibrations different between bigger sizes rubber bands and smaller sized rubber bands?

Answers

Answer 1

Answer: Assuming the kind of vibration you are talking about is the kind where you stretch the rubber band between two points and then "twang" it, then the answer is fairly complex. What happens when you cause the vibrations to start is you make something called a "standing wave". In a standing wave, each particle in the rubber band has a certain amount of energy which causes it to move backwards and forwards, the particles with more energy have a larger "amplitude" (how much they move), and of course the particles with less energy have a smaller amplitude. Now a standing wave has two main components: The amplitude, and the frequency. The amplitude of the whole wave refers to the largest amplitude any particles has. The frequency refers to how often it takes for one of the particles to move between the two furthest away points it can be.
To compare rubber bands, you must remember to keep certain things constant. If you're looking at their vibrations, the amount of energy you use to "twang" the rubber band should be the same each time you twang it (which is the same as applying the same force each time you twang it).

A larger rubber band has more area over which to spread the energy, as well as it has more mass for the energy to move, so the vibrations will have smaller amplitudes, and smaller frequencies, overall vibrating less and with smaller vibrations.

It is unchanged.

This is an excerpt from my lesson in science:

In an ionic compound, every ion is attracted to ions of opposite charge that surround it. It is attracted to ions above, below, and to all sides. The pattern formed by the ions remains the same no matter what the size of the crystal.

In a single grain of salt, the crystal pattern extends for millions of ions in every direction. Many crystals of ionic compounds are hard and brittle due to the strength of their ionic bonds and the attractions among all the ions.

Hence, it is unchanged. (Brainliest Please and 5 stars)

What kind of ions do metals form

Answers

Answer: cations

Explanation:

Metals are defined as the elements which loose electrons to attain stable electronic configuration. If an atom looses electrons, it leads to the formation of positive ions known as cations.

For Example: Sodium looses 1 electron to form $Na^+$ ions.

Non-metals are defined as the elements which gain electrons to attain stable electronic configuration. If an atom gains electrons, it leads to the formation of negative ions known as anions.

For Example: Fluorine gains 1 electron to form $F^-$ ions.
