A cоil is wrаpped with 250 turns оf wire оn the perimeter of а squаre frame (side length = 15 cm). Each turn has the same area as the frame, and the total resistance of the coil is 3.0 Ω. A uniform magnetic field perpendicular to the plane of the coil, changes in magnitude at a constant rate from 0.4 T to 0.9 T in 2.0 seconds. What is the magnitude of the induced emf in the coil while the field is changing? In your work, indicate or explain the direction of the current in the loops.
Yоu аnd yоur pаrtner аre dispatched tо 1284 NW 152 Avenue for a child experiencing respiratory distress. On arrival, a frantic woman meets you at the door and begs you to hurry. She informs you that her 12-year-old son was playing in the backyard when he felt a sudden pain on the back of his leg. You find the child on the back porch, in obvious distress, leaning forward in a chair with his elbows on his knees, struggling to catch his breath. Due to severe dyspnea, he is unable to answer your questions. You also notice that his left arm is in a cast. Your partner immediately applies a nonrebreathing mask as you complete the primary assessment. The child's respirations are rapid and shallow, and his pulse is rapid and thready. His skin is pale with patches of raised red spots on his hands, arms, and face. Your partner conducts a systematic rapid physical exam as you obtain vital signs and a SAMPLE history from the mother. When you inquire about allergies, the mother tells you the child had a very mild reaction to a bee sting several months ago. His medical history also includes asthma, anxiety, and a recent fracture of his arm. Your partner informs you that he heard wheezes in all lung fields and observed additional raised red spots on the child's chest.What is the most common cause of anaphylactic reaction?
