Mrs. Stark has 54,917.2 Joules of energy.
The correct answer for the given question above would be option D. The law that states that a charge cannot be created nor destroyed is the Law of Conservation of Energy. The Law of Conservation of Energy s<span>tates that the total amount of energy in an isolated system remains constant over time. Therefore, it can never be created nor destroyed.</span>
Answer:
q₁ = -2.92 nC
Explanation:
Given;
first point charge, q₁ = ?
second point charge, q₂ = 10 nC
net flux through the surface of the sphere, Φ = 800 N.m²/C
According to Gauss’s law, the flux through any closed surface (Gaussian surface), is equal to the net charge enclosed divided by the permittivity of free space.
where;
Φ is net flux
net charge enclosed
ε₀ is permittivity of free space.
= Φε₀
= 800 x 8.85 x 10⁻¹²
= 7.08 x 10⁻⁹ C
= 7.08 nC
q₁ + q₂ =
q₁ = - q₂
q₁ = 7.08nC - 10 nC
q₁ = -2.92 nC
The air pushes the engine with an equal force in the opposite direction.
Whenever force is used there is an opposite yet equal affect.
