Answer:
I = 4.11 10⁻¹² A
Explanation:
For this exercise we can use Ampère's law, which relates the magnetic flux to the current inside the surface and the magnetic permeability
∫ B. ds = μ₀ I
Let's write a surface that is a circle around the neuron, in this case the direction of the field and the displacement vector are parallel, which reduces the scalar product to an ordinary product
∫B ds = μ₀ I
The field is constant so we take it from the integral that is immediate
B ∫ ds = μ₀ I
B 2π r = μ₀ I
I = B 2π r / μ₀
I = 1.28 10⁻¹⁵ 2π 0.0642 / 4π 10⁻⁷
I = 4.11 10⁻¹² A
Answer:
The best-known power of the Supreme Court is judicial review, or the ability of the Court to declare a Legislative or Executive act in violation of the Constitution, is not found within the text of the Constitution itself. The Court established this doctrine in the case of Marbury v. Madison (1803).
<h3>X-Rays contradict to?</h3>

General relativity involves accelerations (change in velocity), which occur in segments A, C, and E. The spacecraft is flying at a constant velocity (no acceleration) during segments B and D - special relativity would apply in these segments.
Answer:
The speed of the small engine car is <u>_equal to_</u> the speed of the massive cargo car. The magnitude of the acceleration of the small engine car is <u>_equal to_</u> the magnitude of the acceleration of the massive cargo car because <u>_the cars speeds cannot change by different amounts_</u> .
Explanation:
The two cars are connected, hence, they move with the same speed at all points in time.
