The one that research has determined about the orbit of an electron around nucleus is : Each sub-level electron type has a unique path where it will likely to be found
Here are the sub levels of an electron :
-sub level s, maximum number of 2 electrons
- sub level p, maximum number of 6 electrons
- sub level d, maximum number of 10 electrons
- sub level f, maximum number of 14 electrons

Answer:

Each sub-level electron type has a unique path where it will likely be found.

Explanation:

The quantum atomic model is the actual model of an atom. Electrons are present in certain regions called as orbitals. Each orbitals corresponds to some sub levels of energy. These are identified with letters s,p,d and f.

Each orbitals have different shapes like s orbitals are spherical, p orbitals have dumbbell shape etc.

The orbit of an electron around a nucleus is like unique path where it will likely to found. So, the correct option is (c).

Answer:

Δt'/ T% = 90.3%

Explanation:

Simple harmonic movement is described by the expression

x = A cos (wt)

we find the time for the two points of motion

x = - 0.3 A

-0.3 A = A cos (w t₁)

w t₁ = cos -1 (-0.3)

remember that angles are in radians

w t₁ = 1.875 rad

x = 0.3 A

0.3 A = A cos w t₂

w t₂ = cos -1 (0.3)

w t₂ = 1,266 rad

Now let's calculate the time of a complete period

x= -A

w t₃ = cos⁻¹ (-1)

w t₃ = π rad

this angle for the forward movement and the same time for the return movement in the oscillation to the same point, which is the definition of period

T = 2 t₃

T = 2π / w s

now we can calculate the fraction of time in the given time interval

Δt / T = (t₁ -t₂) / T

Δt / T = (1,875 - 1,266) / 2pi

Δt / T = 0.0969

This is the fraction for when the mass is from 0 to 0.3, for regions of oscillation of greater amplitude the fraction is

Δt'/ T = 1 - 0.0969

Δt '/ T = 0.903

Δt'/ T% = 90.3%

A stubborn, 100 kgkg mule sits down and refuses to move. To drag the mule to the barn, the exasperated farmer ties a rope around

jolli1 [7]

Answer:

No, the farmer is not able to move the mule.

Explanation:

Mass =100 kg

Force=F=800 N

The coefficient between the mule and the ground= $\mu_s=0.8$

$\mu_k=0.5$

Static friction force,f= $\mu N$

Normal force=N=mg

Static friction force,f= $\mu_s mg=0.8\times 100\times 9.8=784 N$

Using $g=9.8m/s^2$

F<f

Static friction force is greater than applied force.

Therefore , the farmer is not able to move the mule.
