The resultant combination of the two wheels and the shaft will rotate at approximately half the initial angular speed, ω₀/2.
When the wheel with rotational inertia I₁, initially rotating with angular speed ω₀, is dropped onto the vertical shaft with negligible rotational inertia, the resulting combination of the two wheels and the shaft will rotate at a lower angular speed. The new angular speed can be calculated using the principle of conservation of angular momentum.
According to the conservation of angular momentum, the initial angular momentum of the system must be equal to the final angular momentum. The initial angular momentum is given by the product of the initial rotational inertia (I₁) and the initial angular speed (ω₀). Since the rotational inertia of the shaft is negligible, we can ignore its contribution.
When the wheel is dropped onto the shaft, the total rotational inertia of the system becomes the sum of the rotational inertia of the wheel (I₁) and the rotational inertia of the shaft (I₂), which is negligible. Therefore, the final angular momentum of the system is given by the product of the total rotational inertia and the final angular speed (ω).
Since the initial and final angular momenta must be equal, we have:
I₁ × ω₀ = (I₁ + I₂) × ω
As I₂ is negligible compared to I₁, we can approximate the equation as:
I₁ × ω₀ ≈ I₁ × ω
Simplifying the equation, we find:
ω ≈ ω₀/2
Therefore, the resultant combination of the two wheels and the shaft will rotate at approximately half the initial angular speed, ω₀/2.

If a nucleus had a diameter of 8.0 fm, what would be its expected mass, in atomic mass units?
The atomic mass unit is 37.04unit
The size of a nexus is generally expressed in terms of its compass, not periphery. The compass of a nexus is related to its mass number( A) by a general empirical formula known as the" nuclear compass formula"
[tex]R = R_o(A\frac{1}{3}) ,[/tex]
where R is the compass of the nexus,
R ₀ is a constant( roughly1.2 fm),
and A is the mass number.
To determine the anticipated mass of the nexus in infinitesimal mass units( u), we can use the following equation
Mass = A × mass of a single nucleon,
where the mass of a single nucleon is roughly 1 infinitesimal mass unit( 1 u).
Given that the periphery of the nexus is8.0 fm, we can calculate the compass
R = [tex]\frac{8.0fm}{4.0}[/tex]= 4.0 fm.
Now, we can use the nuclear compass formula to estimate the mass number( A)
fm = R ₀ A(1/3).
By rearranging the formula and working for A,
we have A = ((4.0 fm/ R ₀))
Substituting the value of R ₀( roughly1.2 fm) into the equation
A = ((4.0 fm/1.2 fm))
A ≈(3.33) 3
A ≈37.04.
Thus, the anticipated mass of the nexus in infinitesimal mass units would be roughly37.04u.

Violet color in the visible spectrum has the highest frequency. The violet colour has the greatest frequency of all the colours in the visible spectrum.
The range of electromagnetic waves that can be seen by the human eye is known as the visible spectrum, and it contains colours from red to violet. Based on their wavelengths, light waves that travel through a prism or diffract split into various colours.
The shortest wavelength of all the colours that may be seen, violet, correlates to a high frequency. Wavelengths and frequencies gradually change as we go from violet to red. As a result, violet has the greatest frequency of all the colours in the visible spectrum.

If answer is correct I'll rate you five stars a thanks and maybe even brainliest!
Please can you explain what this paragraph is trying to say. Also what does it mean in the sentence 'the difference in charge across the battery provides push for current' and what is the difference in charge.
Here's paragraph I need to have a simple definition of:
A high waterfall is also like a large voltage. It will transfer a lot of energy to the water (charge), making the river flow very fast (a large current) the difference in height makes the river flow. In a circuit , the difference in charge across battery provides push for the current.
