The part of an atom that is mostly empty space is the Cloud/Mist/Fog

According to the latest atomic model, the atomic nucleus is surrounded by fog / cloud of electrons

\large{\boxed{\boxed{\bold {Further ~ explanation}}}

Rutherford scientists experimented with firing alpha rays on a thin gold plate. From this experiment, it was found that:

  • 1. Most alpha rays are passed through the gold plate, so it is concluded that most space in the atom has empty space
  • 2. A small number of alpha particles that show there are positively charged particles inside the atom(at this time these particles are called protons located in the atomic nucleus)

From here comes the Rutherford atomic model which states that the initiates are charged particles and negatively charged electrons around the nucleus.

So that from this atomic model it shows most of the volume of atoms filled by electrons and between atomic nuclei and electrons is empty space

According to the latest atomic model, the atomic nucleus is surrounded by fog/cloud of electrons. If there is an incoming beam of light that is fired at the atom, then the light can be forwarded or absorbed into this electron mist/cloud

<h3><u>Answer;</u></h3>

Electron cloud

<h3><u>Explanation;</u></h3>
  • <em><u>An atom is the smallest particle of an element that can take part in a chemical reaction. Atom is made up of two parts ; that is the nucleus and the electron cloud. The nucleus contain subatomic particles; protons and neutrons, while the electron cloud contains the electrons.</u></em>
  • <em><u>The electron cloud is the largest part of the atom and is mostly an empty space. Most of an atom is a cloud of electrons surrounding a space called the nucleus with tiny protons and neutrons.</u></em>

A simple pendulum is used to determine the acceleration due to gravity at the surface of a planet. The pendulum has a length of
SVEN [57.7K]

Answer:

Acceleration due to gravity is 20 m/sec^2

So option (E) will be correct answer

Explanation:

We have given length of the pendulum l = 2 m

Time period of the pendulum T = 2 sec

We have to find acceleration due to gravity g

We know that time period of pendulum is given by

T=2\pi \sqrt{\frac{l}{g}}

2=2\times 3.14 \sqrt{\frac{2}{g}}

0.3184= \sqrt{\frac{2}{g}}

Squaring both side

0.1014= {\frac{2}{g}}

g=19.71=20m/sec^2

So acceleration due to gravity is 20 m/sec^2

So option (E) will be correct answer.

Rod A and rod B are cylindrical rods made of the same metal. amd they differ only in size. Rod B has double the length and doubl
Mice21 [21]

Answer:

it would take rod B twice as much time

Explanation:

it would take rod B twice as much time as it is twice as thick and twice as long. Due to this reason it would take the electric charge not only more time but even more voltage to travel through the rod

The half-life of carbon-14 is 5730 years. how long will it take for 7/8 of a sample of carbon-14 to decay
wlad13 [49]
The half life of Carbon-14 is 5730 years, how many years would it take for 7/8 of the original amount to decay? 

<span>Can somebody please help with this problem. I *think* I understand the basics of what a half life is. If I learned correctly, its the amount it takes for half of a sample to decay. It should also happen exponentially, 1/2 remaining after one half life, 1/4 after the second, 1/16 after the third etc. I'm still a little shaky though. Could somebody please clarify what exactly a half life is and how it can be determined (i.e. how to find the time it would take for 7/8 to decay) </span>

A motorcyclist accelerates from rest to 10 mi/hr. what is the change in velocity
gulaghasi [49]

The change in velocity is 10 mi/h (4.47 m/s)

Explanation:

The change in velocity of the motorcyclist is given by

\Delta v = v-u

where

v is the final velocity

u is the initial velocity

In this problem, we have

u = 0 (the motorbike starts from rest)

v = 10 mi/h

Therefore, the change in velocity is

\Delta v = 10 -0 = 10 mi/h

And keeping in mind that

1 mile = 1609 m

1 h = 3600 s

We can convert it into m/s:

\Delta v = 10 \frac{mi}{h} \cdot \frac{1609 m/mi}{3600 s/h}=4.47 m/s
