Approximately 80% of the energy used for active transport is devoted to the reabsorption of sodium. Hope this helped, have a great day! :D

Effort force and Resistance force
Answer:
182.5 s
Explanation:
From the law of conservation of angular momentum,
I₁ω₁ = I₂ω₂
where I₁,ω₁ are the rotational inertia and angular speed of the star and I₂,ω₂ are the rotational inertia and angular speed of the white dwarf star
I₁ = 2/5MR₁² where M = mass of star and R₁ = radius of star = radius of sun = 696340 km
I₂ = 2/5MR₂² where M = mass of white dwarf star = mass of star and R₂ = radius of white dwarf star = radius of earth = 6400 km
ω₁ = 2π/T₁ where T₁ = period of star = 25 days = 25 × 24 × 60 × 60 s = 2.16 × 10⁶ s
ω₂ = 2π/T₂ where T₂ = period of white dwarf star.
So, I₁ω₁ = I₂ω₂
2/5MR₁² × 2π/T₁ = 2/5MR₂² × 2π/T₂
R₁²/T₁ = R₂²/T₂
T₂ = T₁R₂²/R₁² = 2.16 × 10⁶ s × (6400 km/696340 km)² = 182.5 s
Answer:
The equilibrant force that will keep the object in equilibrium is;
A. 10 N to the left
Explanation:
The forces acting on the object are;
A 20 Newton force acting to pull the object horizontally to the left
A 30 Newton force acting to pull the object horizontally to the right
For equilibrium, we have;
The sum of forces acting on the object, ∑F = 0
Let '' represent the equilibrant force, with a convention of right = positive, we have;
At equilibrium, ∑F = 30 N - 20 N + = 0
∴ 30 N - 20 N + = 0
10 N = -
∴ = -10 N
With the convention that a force acting to the right = Positive, we have the equilibrant force, = -10 N which is negative, is acting towards the left;
∴ The equilibrant force that will keep the object in equilibrium, = 10 N acting to the left.
