A fixed 14.4-cm-diameter wire coil is perpendicular to a magnetic field 0.65 T pointing up. In 0.20 s , the field is changed to 0.16 T pointing down. Part A What is the average induced emf in the coil?

Afeather of mass 0.001 kg falls from a height of 2 m. under realistic conditions, it experiences air resistance. based on what you know about friction, what can you say about the kinetic energy of the feather as it reaches the ground? acceleration due to gravity is g = 9.8 m/s2. a. ke < 0.0196 j b. ke = 00196 j c. je = 0 j d. ke > 0.0196 j
