So in this problem, we know that the power P is 500 ports and the V R. M s is 1 20 boats. So, uh, I r m s equal on our Emma's equal P D Bye bye v r m s. All right, so this gives you let me see. All right. Uh, 50 Dubai by 12. Uh, well, don't let me use the calculator. $50.12. So that is 4.17 So it's a full 0.17 and peers. And because we want to find out the pick value of the current. So I note equal square two times I or I miss. So the better is, uh, times this one. So the bet is a 5.9. It's ah, 5.9 appears. Okay.
