Answer:

Quarks are usually defined as sub-atomic particles that are combined with one another and results in the formation of hadrons, of which the protons and the neutrons. They are a little heavier than the electrons and have a size of about 10^-18 m.

There are a total of 6 types of quarks, and they are as follows-

Top quark

Bottom quark

Up quark

Down quark

Strange quark

Charm quark

The up-quark is commonly represented as u-quark, and it forms the lightest of all the quarks. It is one of the main constituents of matter. It occurs along with the down-quarks and forms the neutron.

Erwin Schrödinger developed the quantum model of the atom. What scientific knowledge was necessary for Schrödinger’s work?

Vikki [24]

The scientific knowledge was necessary for Schrödinger’s work is the discoverd of electron.

<h3>What is electron and how was it discovered?</h3>

Thomson carried out new experiments that led him to conclude that cathode rays were formed by particles that have a negative charge. Later, Thomson proved that these rays were deflected by applying an electric field. Thus, these particles were called electrons.

The discovery of the electron allowed Schrodinger to explain quantum models that are based on how electrons behave.

An electron is moving in the presence of an electric field of 400 N/C. What force does the electron experience?

yanalaym [24]

Answer:

Explanation:

Given

Electric Field strength $E=400\ N/C$

charge of electron $q=1.6\times 10^{-19}\ C$

Force on the charge particle is given by

$F=qE$

$F=1.6\times 10^{-19}\times 400$

$F=640\times 10^{-19}\ N$

but this force will be acting in the direction opposite to the direction of Electric field because electron is negatively charged

You are sitting 3 m away from you friend who is watching a cartoon on his phone. How will the sound itensity change if your frie

Zinaida [17]

Answer:

Decreases by $3.6 \times 10^{-3}$ times

Explanation:

The intensity of a sound is defined as the energy of the sound that is flowing in an unit time through the unit area which is in the direction that is perpendicular to the direction of the sound waves movement.

The intensity of energy is described by the inverse square law. It states that the intensity varies inversely with the distance square of the distance.

In other words, the sound intensity decreases as inversely proportional to the squared of the distance. i.e. $\frac{1}{r^2}$
