Rutherford’s model of the atom included a nucleus  that Thomson’s model did not have, therefore the correct option is A

What are atomic models?

There are some models that are used to explain the arrangements of subatomic particles inside the atom based on the atomic theory of atom are known as the atomic models.

There are many types of atomic models proposed in past based on their individual assumptions and the experimentations

There are mainly five most widely accepted atomic models

John Dalton's atomic model which based on the assumption that all the entities of the universe are made up of the fundamental particle that is an atom.

J.J. Thomson's model: Plum Pudding model explains the arrangement of subatomic particles by taking the example of plum pudding in which positive charge is distributed uniformly throughout and the negative charge particles are sprinkled on it in a random fashion.

Rutherford's model explained the existence of a nucleus inside the atom by using the alpha particle bombardment experiment on a thin sheet of gold.

Niels Bohr's model explained the revolving nature of the electrons in the different shells around the nucleus of the atom.

Erwin Schrodinger's model explains the arrangement of the subatomic particles as the electron Cloud Model also known as the Quantum Model.

A train is travelling east along a straight run of track at 54.0 km/hr. Inside, two siblings 1.90 m apart are playing catch directly across the aisle. The kid wearing a Catherine Wheel T-shirt throws the ball horizontally north. The ball crosses the train and is caught 1.05 s later by her little brother. (Ignore any effects of gravity or friction.)
a) Find the magnitude of the ball's velocity from the little brother's point of view.
b) What is the magnitude of the velocity of the ball as seen by someone standing still outside the train?
c) What is the angle between the direction of the ball and the direction of the train as measured by someone standing still outside the train?

Answers

Answer:

A.) 1.81 m/s

B.) 16.07 m/s

C.) 6.88 degree.

Explanation:

Given that Inside, two siblings 1.90 m apart are playing catch directly across the aisle. The kid wearing a Catherine Wheel T-shirt throws the ball horizontally north. The ball crosses the train and is caught 1.05 s later by her little brother.

The velocity of the ball will be

Velocity = displacement/ time

Where displacement = 1.90 m

Time = 1.05 s

Velocity = 1.9 / 1.05

Velocity = 1.8095

Velocity = 1.81 m/s

A.) From the little brother point of view, the magnitude of ball's velocity will be 1.81 m/s

B.) The magnitude of the velocity of the ball as seen by someone standing still outside the train will be achieved by first converting km/h to m/s

(54 × 1000) / 3600 = 15 m/s

Then, use pythagorean theorem to find the velocity

V = sqrt ( 15^2 + 1.81^2)

V = sqrt ( 225 + 3.2761)

V = sqrt ( 258.2761)

V = 16.07 m/s

C.) The angle will be

Tan Ø = 1.81 / 15

Tan Ø = 0.1206666

Ø = tan^-1(0. 1206666)

Ø = 6.88 degree.

Answers

Answer:

Explanation:

An atom is said to be electrically neutral, if the said atom contains equal or the same numbers of protons and electrons.

Worthy of note is that most bodies are normally close to being electrically neutral. This is because of the number of electrons on the body being equal to the number of protons on the same body. Charging a body means one would have to transfer electric charge to the body, or from the body. As a result, the number of electrons in the body will no longer be equal to the number of protons on the body.
