Scientific knowledge is built as people come up with hypotheses and theories, repeatedly check them against observations of the natural world and continue to refine those explanations based on new ideas and observations.
Answer:
43.83 nC
Explanation:
We know Q = ε₀Ψ where Q = charge enclosed by the cubic box, ε₀ = permittivity of free space = 8.854 × 10⁻¹² F/m and Ψ = net electric flux through cubic box = 4950 Nm²/C
So, substituting the values of the variables into the equation, we have
Q = ε₀Ψ
= 8.854 × 10⁻¹² F/m × 4950 Nm²/C
= 43827.3 × 10⁻¹² C = 4.38273 × 10⁻⁸ C
= 43.8273 × 10⁻⁹ C
= 43.8273 nC
≅ 43.83 nC
<span>Car B has a greater momentum than car A.
Since, momentum = mass * velocity
mass of both car A and B is same, velocity of B is greater than A.
So, momentum of car B = 1200 * 25 = 30,000 kg-km/h is greater than </span>momentum of car A = 1200 * 22 = 26400 kg-km/h
