This Is Chemistry Question, My Laptop Got Lag When I was Posting It :( Explain The Rutherford Atomic Model
Answer Should Be given With Headings!
Answers
Explanation:
that’s hard
Answer:
Rutherford conducted an experiment (α-particles scattering) in order to find the arrangement of electrons and protons in an atom. This experiment led to the discovery of nucleus in an atom.
Explanation:
Rutherford bombarded a thin gold foil (about 0.00004 cm thick) with alpha particles in an evacuated chamber. These particles got scattered and were allowed to to strike on a circular zinc sulphide coated screen. He observed a flash of light on the screen where the alpha particles struck. From this experiment, he made the following conclusions.
Observation 1: Most alpha particles (α-particles) pass straight through the gold foil without any deflection from their original paths.
Conclusion: There is a lot of empty space in the atom.
Observation 2: A few alpha particles were deflected, at small angles and a few at large angles.
Conclusion: There is a small positively charged object at the centre of the atom. He said this because as alpha rays are positively charged it can pass through only negatively charged particles and get deflected by the same charge. He concluded that the small positively charged object present within the atom is called the nucleus.
Observation 3: Very few alpha particles completely rebounded on hitting the gold foil.
Conclusion: The nucleus is dense and hard. It is located at the centre of the atom.

What is observed as the distance between the rest position and the crest of a light wave decreases?
A. The light becomes more violet
B. The light becomes dimmer
C. The light becomes brighter
D. The light becomes more red
Answers
Answer: answers B
Explanation: it gets dimmer becuase less light......
As it is observed the distance between the rest position and the crest of a light wave decreases, and the light becomes dimmer, therefore the correct answer is option B.
What is Wavelength?It can be understood in terms of the distance between any two similar successive points across any wave for example wavelength can be calculated by measuring the distance between any two successive crests.
C = λν
As given in the , it is observed the distance between the rest position and the crest of a light wave decreases,
The right response is option B since it can be seen that when the distance between the rest position and the crest of a light wave decreases, the light becomes dimmer.

If I increase my mass (by putting in books in the box) shouln't my acceleration go down since they are inversely related to each other (when one goes up, the other goes down and vice versa). My force stayed the same at 10 N, thus only mass and acceleration fluctuated relative to each other.

Step-by-Step Explanation:
We know, F = ma
m = 200kg
a = 2 m/s^2
Therefore,
= m * a
= 200 * 2
= 400 N
If this Answer helped, please mark it as Brainliest. Thank you!
You find the answer by solving the problem.
You can solve the problem by using the equation that tells how force, mass, and acceleration are connected.
The equation is in the "Hint".
F = m • a
Force = mass • acceleration
mass = 200 kg
acceleration = 2 m/s^2
Force = (2000 kg) • (2 m/s^2)
Force = 400 Newtons

b. Describe how the arrangement of the books can be changed for the greatest overall potential energy when only one book is on each shelf.
Answers
a. P.E(Y)< P.E(W)< P.E(Z)< P.E(X)

What is gravitational potential energy?If an object is lifted, work is done against gravitational force. The object gains energy.
The equation for calculating gravitational potential energy is
GPE =mgh
where, GPE is the gravitational potential energy, m is the mass, h is the change in height and g is the acceleration due to gravity.
a) According to the heights of books, P.E(Y)< P.E(W)< P.E(Z)< P.E(X)
when arranged for lowest potential energy, book with the lowest mass will be placed in the lower position. Thus, relationship among masses, m(Y)< m(W)<m(Z)<m(X)
b) The arrangement of the books can be changed for the greatest overall potential energy when only one book is on each shelf. The books arranged with book X in the bottom, book Z in 2nd position, book W in 3rd and book Y on the top.
