Answer:

Explanation:

Meteorites falls are those which are collected just after knowing it is falling, whereas meteorites find are found at later times.

Iron meteorites have higher percentage of find because people have found that they are useful and have great qualities. They collect such meteorites thus removing them from scientific record.

The iron meteorite consist of iron nickle alloy and is a usable iron source for humans. Iron meteorites are more resistance to weathering and can easily survive atmospheric entry hence are found in large pieces.

Because of all such features, people collect them and make their most of use, hence its find percentage is higher.

Answer:

Depends.

Explanation:

Whether the object is going left or right, the speed will stay the same until friction eventually stops it. However, if, for example, we're talking about an object going straight before veering right, then yes, speed does matter. An object will normally have to speed up or slow down momentarily when changing direction to keep itself sustained on the ground.

So, honestly? It really depends on what we're talking about!

Hope this helped!

A. Besides protons, what other particles make up an atom? Write 2 - 3 sentences describing how the electrostatic force acts betw

vodomira [7]

Answer:

For a. Neutrons and electrons also form an atom.

For b. The element is oxygen which is a non-metal and will form a negative ion while forming ionic bond.

Explanation:

For a:

There are 3 subatomic particles which form an atom. These are neutrons, protons and electrons.

Neutrons carry no charge, protons carry positive charge and electrons carry negative charge. Neutrons and protons are present in nucleus and electrons revolve around the nucleus.

The energy which is present between neutrons and protons are nuclear energy and the energy which is present between electrons and protons are electrostatic energy.

For b:

In an element, number of protons is always equal to the number of electrons. The atomic number is equal to the number of protons or electrons. The element which has atomic number 8 is Oxygen.

The electronic configuration of this element is $1s^22s^22p^4$

This element requires only 2 electrons to form a stable electronic configuration. An element which gains electron is considered as a non-metal and forms a negative ion because number of electrons increases.
