How did Rutherford's experimental evidence lead to the development of a new atomic model?

Answers

In his Gold Foil experiment, few particles were deflected strongly, where as he thought all particles will go straight through the foil (some did though, which are called electrons.) J. J. Thompson, Rutherford's former teacher, proposed that if there are negative charge particles (he named them electrons), there must also be a positive charge particles; Rutherford proved his theory right, and he called the positive charge protons. He also found that inside the atom, there must be a positive charge that is clustered in a tiny region in its center, which is called the nucleus.

What is the study of how matter and energy interact? A. Biology B. Chemistry C. Planetary science D. Physics

Answers

Answer:

D. Physics

Explanation:

First, let's define all the answer choices.

Biology: Biology is the study of life and living things. Biology deals with the function, growth, origin and more of organisms.

Chemistry: Chemistry is the study of matter, elements, atoms, compounds, molecules and more. Chemistry is also concerned with chemical reactions.

Planetary science: Planetary science is basically the study of planets. This is the study of planets, moons and planetary systems.

Physics: Physics is the study of matter, energy, and their interactions. This helps us to explain and understand things that happen in the universe.

The best choice is D. Physics. Physics is the study of how matter and energy interact.

Final answer:

The D. Physics is the study of how matter and energy interact. It helps us understand how things work and why they behave the way they do.

Explanation:

Physics is a natural science that explores the fundamental principles governing the universe. It studies the behavior of matter, energy, space, and time through the formulation of physical laws and mathematical equations. Physics covers diverse topics, including mechanics, electromagnetism, thermodynamics, relativity, quantum mechanics, and astrophysics, explaining phenomena from the subatomic to cosmic scales.

Thus, it is the study of how matter and energy interact. It is concerned with describing the interactions of energy, matter, space, and time to uncover the fundamental mechanisms that underlie every phenomenon. In simple terms, physics helps us understand how things work and why they behave the way they do.
