In a region of space, a magnetic field points in the +x-direction (toward the right). its magnitude varies with position according to the formula bx=b0+bx, where b0 and b are positive constants, for x≥0. a flat coil of area a moves with uniform speed v from right to left with the plane of its area always perpendicular to this field. part a what is the emf induced in this coil while it is to the right of the origin?

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
