Compared with an Earth year, a galactic year represents time on a grand scale but its not a consistent measurement across the galaxy
Reflection from such a rough surface is called diffuse reflection and appears matte
Answer:
Vc = 2.41 v
Explanation:
voltage (v) = 16 v
find the voltage between the ends of the copper rods .
applying the voltage divider theorem
Vc = V x ()
where
- Rc = resistance of copper = (l = length , a = area, ρ = resistivity of copper)
- Ri = resistance of iron = (l = length , a = area, ρ₀ = resistivity of copper)
Vc = V x ()
Vc = V x ()
Vc = V x ()
where
- ρ = resistivity of copper = 1.72 x 10^{-8} ohm.meter
- ρ₀ = resistivity of iron = 9.71 x 10^{-8} ohm.meter
Vc = 16 x ()
Vc = 2.41 v
