Answer:
<em>The reactance is 80 Ω</em>
<em></em>
Explanation:
Inductance H = 2 H
voltage v = 10 V
angular speed ω = 40 rad/s
The reactance of an inductive ac circuit ωL
40 x 2 =<em> 80 Ω</em>
<em></em>
The current in the circuit is = V/ = 10/8 = 1.25 A
4. NaOH

I think the answer is visible light because all the other ones have a wave at the end
The correct answer is 42. I know this answer is right because i have already turned my assignment in and got it right.
Answer:
5.8125*10^-3
the moles in Fe2O3 are 0.93/(56*2 + 16*3) = 5.8125*10^-3
