Answer:
The magnitude of the force per unit of lenght between the wires are of F/L= 3.17 * 10⁻⁵ N/m.
Explanation:
d=0.0665m
I1=I2= 3.25A
μo= 4π * 10⁻⁷ N/A²
F/L= (μo * I1 * I2) / (2π * d)
F/L= 3.17 * 10⁻⁵ N/m
B.Aluminum because its the poorest out of the other 3
100-25=75
speed=distance/time so time=distance/speed
75/15 =5 seconds
Answer:
the two beams must travel paths that differ by one-half of a wavelength.
