The homologous structures and the analogous structures of different species.
Explanation:
The similarities of the inner and outer planets are The inner planets are often referred to as “terrestrial” or “rocky” planets. The outer planets, meaning those planets outside the asteroid belt, are called “gas giants.” The terrestrial planets are small (astronomically speaking). Earth is the largest one, with a diameter of about 8000 miles
Answer:
The physical properties of matter are any properties that can be perceived or observed without changing the chemical identity of the sample. In contrast, chemical properties are those that can only be observed and measured by performing a chemical reaction, thus changing the molecular structure of the sample. Mass (like volume) is an extensive physical property because its value depends on the quantity of the matter, unlike temperature. It is not a chemical property as its measurement includes no chemical reaction and change.
Hope this helps!
Answer:
C. Fe will stay positive and increase in magnitude.
Explanation:
Coulomb's law states that the force of attraction of repulsion between two charged particles is directly proportional to the magnitude of their charges and inversely proportional to the square of the distance of separation between them.
This means that if the size of the charges are large, the force acting on them will be large as well. Also if the distance between the two charges increases the force decreases. However, the force increases when the distance of separation decreases.
Like charges repel, therefore, two negative charges brought together will repel each other, and the distance between the two charges decreases, the force will increase in magnitude. Forces of repulsion are considered positive, therefore, the force, Fe, will stay positive and increase in magnitude.
