A long, straight, conducting wire carries a current of 1.50 A. A second, identical wire is parallel to the first and separated from it by 3.50 cm. The magnetic field at a point halfway between the two wires has magnitude 5.50 × 10-5 T. What is the current in the second wire if its direction is the same as in the first wire? Express your answer with the appropriate units. Ti HẢ 圈] I2 = Value Units Submit Request Answer Part F What is the current in the second wire if its direction is opposite to that in the first wire? Express your answer with the appropriate units. I2 = Value Units

Q19

(2) The box with M = 40kg shown below is being pulled by two pulleys exerting forces F₁ = 400 N (0₁ = 60°) and F₂ = 200 N (0₂= 15°) up an incline with an angle 0₁ = 30°. If the uk = 0.15. What is the acceleration of the box? Would the F₁ or F₂ be enough alone to pull the box up if the other pulley would stop working?
