You are right! Thanks

Because the question says 1280 turns per meter

Homework Statement A single-turn square loop of side L is centered on the axis of a long solenoid. In addition, the plane of the square loop is perpendicular to the axis of the solenoid. The solenoid has 1280 turns per meter and a diameter of 5.85 cm , and carries a current of 2.15 A . Find...

Oh no, I'm sorry! Won't do it again!

Hey! Sorry for reviving this old thread, but I am doing this same question and am confused on the x-coordinate part. For before the rotation, you did x-cord: (4 x 0.75) + (3 x 1.5) + (2 x 1.5)/(4 + 3 + 2) = 10.5/9 However, shouldn't it be x-cord: (4 x 0.75) + (3 x 0) + (2 x 0)/(4 + 3 + 2) =...

Hey Bruce! Haha you are right! Opps! Thank you!

Homework Statement The cosmoclock 21 Ferris Wheel in Yokohama City, Japan, has a diameter of 100m. Its name comes from its 60 arms, each of which can function as a second hand (so it makes one revolution every 60.0s). a) Find the speed of the passengers when the Ferris wheel is rotating at...

Thanks! But shouldn't tension be pointing in the other direction? So towards the top-right instead of bottom left?

Homework Statement Two blocks, each with weight w, are held in place on a frictionless incline as shown in Figure. In terms of w and the angle a of the incline, calculate the tension in the rope connecting the blocks Homework Equations T = mg The Attempt at a Solution I cannot for figure out...
