What are the differences between the plum pudding model, nuclear model and the atomic model

2 answers:

8 0

The plum pudding diagram models the protons and electrons in an atom and gives evidence of different charges in an atom. The nuclear model was made to prove that the subatomic particles were placed in different places in the atom such as the neutrons and protons being in the nucleus and the electrons on the outer shells. The atomic model, buy Dalton, was made to prove that the atom is always in constant motion and never still in one place.

HOPE THIS HELPED :)

The plum pudding model suggested that the electrons were dispersed throughout the atom (like chocolate chips in a cookie) and the space was positively charged so that in the end the atom was neutral. Today, people know that the electrons are in a "cloud" around the atom and the protons (and neutrons) are in the nucleus, at the center of the atom.

Earth can be modeled with five layers based on the strengths and physical properties of the materials in them. Put the layers in

andre [41]

Answer:

Crust, Upper mantle, mantle, outer core, inner core

Explanation:

The Earth's layers have been clasified in 5 according to the materials that conform them, theri physical properties, strengths and also their state of matter. We all know how the outer layer of the Earth looks like, but if we start to dig a huge hole we are going to see different types por materials due to a change in pressure, temperature, and other factors. At the very center of the Earth there's what's called "core". The core is liquid and at extremely high temperatures. This is because of the enormous amount of pressure the rest of the Earth is putting it under. So, if we list the different layers of the Earth according to the materials they are made of, from the Earth's surface to the core, the answer is:

1) Crust (surface)

2) Upper Mantle

3) Mantle

4) Outer core

5) Inner core

In some books you may find a layer called Lithosphere. Tis layer consists not only of the crust, but also it contains the transition zone between the upper mantle and the crust.

If a bow holds 500J of potential energy as the arrow is pulled back, how much kinetic energy will the arrow have after it has be

ale4655 [162]

Answer:

500J

Explanation:

The arrow will have an energy of 500J after it has been released from its state of rest.

This is compliance with the law of conservation of energy which states that "in every system, energy is neither created nor destroyed but transformed from one form to another".

The energy at rest which is the potential energy is 500J
This energy will be converted to kinetic energy in total after the arrow has been released.
This way, no energy is lost and we can account for the energy transformations occurring.
