The only way to remain in orbit indefinitely is to make sure that no part of the orbit passes through any air molecules. There are too many of those in a low earth orbit. So a low earth orbit gradually loses energy when the satellite hits air molecules.
D: the number of protons determines the atomic number of an atom
Answer:
Zero
Explanation:
The magnetic field due to the first wire on the second wire with current i₁ in the first wire at a distance d from the second wire is B₁ = μ₀i₁/2πd.
The magnetic force due to this field on the second wire of length segment, L and current i₂ is F₁ = Bi₂L = (μ₀i₁/2πd)i₂L = μ₀i₁i₂L/2πd = F
The magnetic field due to the second wire on the first wire with current i₂ in the first wire at a distance d from the second wire is B₂ = μ₀i₂/2πd.
The magnetic force due to this field on the first wire of length segment, L and current i₁ is F₂ = Bi₁L = (μ₀i₂/2πd)i₁L = μ₀i₁i₂L/2πd = F
Since their magnetic fields are in opposite directions, according to the right hand rule, their forces would also be in opposite directions.
So F₁ = F and F₂ = -F
So their vector sum F₁ + F₂ = F +(-F) = F - F = 0
