The electron in a hydrogen atom is typically found at a distance of about 5.3 x 10-11m from the nucleus, which has a diameter of about 1.0 x 10-15m. Suppose the nucleus of the hydrogen atom were enlarged to the size of a baseball (diameter = 7.3cm). At what typical distance from the center of the baseball would you expect to find the electron?
A 50-turn loop of wire has a cross-sectional area of 0.010 m^2. It is rotated about an axis perpendicular to the earth's field of 5.0 × 10^-5 T. What is the peak value of the emf generated if the loop rotates at 3600 rotations per minute?
