A semi-infinite straight wire lies along the x-axis, from the origin to x = +[infinity]. The magnetic field on the y-axis at y = 0.044 m is 3.4 μT . What is the current through the wire?

I = 1.496A

Explanation:

B = (U₀ I/4πr) =3. 4 × 10⁻⁶T

3. 4 × 10⁻⁶ = 10⁻⁷ × I/0.044

I = 1.496A

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

happy to

pls mark as brainliest.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
