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 child pushes a 100 kg refrigerator with a force of 50 N, but the refrigerator does not move. Suppose the coefficient of static
faust18 [17]

Answer:

50 N

Explanation:

Since the refrigerator doesn’t move, that means the force of friction equals the amount of force the child exerts on the fridge. If the friction force were greater than the force by the child, the fridge would start accelerating towards the child. If it were less than the force the child exerted, the fridge would start accelerating away from the child. Therefore, the net force must be 0, in this case, the friction force is equal to the force the child exerted, for it to stay at rest (as Newton’s First Law stated).

I hope this helps! :)

A sailor in a small sailboat encounters shifting winds. She sails 2.00 km east, then 3.50 km southeast, and then an additional d
Law Incorporation [45]

Answer:

Third displacement = 2.81 m which is 61.70° north of east.

Explanation:

   Let east represents positive x- axis and north represent positive y - axis. Horizontal component is i and vertical component is j.

  She sails 2 km east, displacement = 2 i

  Then 3.50 km southeast, means 3.5 km 315⁰ to + ve X axis

  Displacement = 3.5 cos 315 i + 3.5 sin 315 = 2.47 i - 2.47 j

  Let third displacement be x i + y j

  We have final displacement = 5.80 km east = 5.80 i

  From summation we have total displacement = 2 i + 2.47 i - 2.47 j + x i + y j

                                                                           = (4.47+x) i + (y - 2.47) j

  Comparing both , we have 4.47+x = 5.80

                                                        x = 1.33

                                                 y-2.47=0

                                                         y = 2.47 j

  So third displacement = 1.33 i + 2.47 j

  Magnitude of third displacement = \sqrt{1.33^2+2.47^2} =2.81m

  θ = tan⁻¹(2.47/1.33) = 61.70°

  So third displacement = 2.81 m which is 61.70° north of east.

A copper sphere 10 mm in diameter is dropped into a 1-m-deep drum of asphalt. The asphalt has a density of 1150 kg/m3 and a visc
kvasek [131]

Answer:

t = 1964636.542 sec

Explanation:

Given data:

sphere diameter is 10 mm

Density is 1150 kg/m^3

viscosity 105 N s/m^2

We knwo that time taken by sphere can be calculated by following procedure

\tau = \mu \frac{du}{dy}

\frac{F}{A} =  \mu \frac{du}{r}

\frac{\rho_C -\rho_{asphalt} gv}{2 \pi rL} = 10^5 \frac{du}{r}

Solving for du

du = \frac{ (8933 - 1150) 9.81 \frac{4}{3} \pi (10\times 10^{-3})^3}{2\pi \times 1\times 10^5}

du = u = 5.09\times 10^{-7}

u = \frac{1}{t}

t = \frac{1}{5.09\times 10^{-7}} = 1964636.542 sec
