Two long, parallel wires, each having a mass per unit length of 37.5 g/m, are supported in a horizontal plane by strings ℓ = 6.15 cm long. when both wires carry the same current i, the wires repel each other so that the angle between the supporting strings is θ = 16.2°.

Objects a and b are visible in the night sky. six months later they are still visible, but object b shows less parallax than object a. which object is closer? a. a b. b c. you would need to wait another six months in order to figure this out. d. you would need to know the objects' angular diameters in order to figure this out.
