Answer:
10°C
Explanation:
To convert °F to °C, we use the formula:
°C = (°F - 32) * ( 5/9)
So, to convert 50°F to the equivalent in °C, we can proceed as follows:
°C = ( 50 - 32 ) * (5/9)
°C = ( 18 ) * (5/9), which is, approximately,
°C = 9.999999999... ≈ 10 (5/9 ≈0.555555...)
So, 50°F is equivalent to 10°C.
Answer:
The atomic mass unit is 1/12 of an atom of carbon 12, and is a very small amount to represent in kilograms:
is atomic mass unit.
This is why the benefits of the atomic mass unit is that it makes the representation of atomic masses easier in terms of the simplicity of the numbers that are used to represent the masses. Also using the atomic mass unit it is easier to compare the masses of different atoms, These numbers would be very small and would require negative powers of 10 to represent them, so it is more convenient to use the atomic mass unit.

Explanation:
Assuming a uniform mass, let's say ρ is the mass per area density.
ρ = M / (πR²)
Let's look at this as the difference of two disks, a large one and a small one.
The moment of inertia of the large disk is:
I = 1/2 MR²
The mass of the small disk is:
m = ρ πr²
m = M / (πR²) πr²
m = M (r/R)²
Using parallel axis theorem, the moment of inertia of the small disk is:
I = 1/2 mr² + md²
I = 1/2 M (r/R)² r² + M (r/R)² d²
I = 1/2 M (r²/R)² + M (rd/R)²
The total moment of inertia is:
I = 1/2 MR² − 1/2 M (r²/R)² − M (rd/R)²
