Explanation:
Buoyancy force is equal to the weight of the displaced fluid:
B = ρVg
where ρ is the density of the fluid,
V is the volume of the displaced fluid,
and g is the acceleration due to gravity.
The fluid is water, so ρ = 1000 kg/m³.
The volume displaced is that of a sphere with radius 2 m:
V = 4/3 π r³
V = 4/3 π (2 m)³
V ≈ 33.5 m³
The buoyancy force is therefore:
B = (1000 kg/m³) (33.5 m³) (9.8 m/s²)
B ≈ 328,400 N
Round as needed.
Answer:
True
Explanation:
Pauli exclusion principle states that in an atom, no two electrons have same set of the quantum numbers. The electrons in an atom have a unique set of quantum numbers ,
Even the electron is in same shell, same subshell and same orbital, the spin quantum number will be different for the two of them.
For example : 2 electrons in
n = 2 , l = 1 , m = 1 but s is different for both of them . (+1/2 or - 1/2)
The equation that shows the relationship between X₁ and X₂ in the springs is X₁ = 4X₂.
<h3>How to compute the equation?</h3>
From the complete question, for case I, the two springs stretch up to the distance of X₁. Therefore, f = mg = kx₁.
For case 2, f = mg = kx₂.
Therefore, we'll equate the equations. This will be:
Kx₁ = Kx₂
(K/2)x₁ = (2k)x₂
K(x₁/2) = k(2x₂)
X₁/2 = 2x₂
X1 = 2 × 2x₂
X₁ = 4X₂.
In conclusion, X₁ = 4X₂.
