The Voyager I spacecraft moves through interstellar space with a speed of 7400m/s . The magnetic field in this region of space has a magnitude of 2.5×10?10 T.
Assuming that the 5.6-m long antenna on the spacecraft is at right angles to the magnetic field, find the induced emf between its ends.
An undamped 1.42-kg horizontal spring oscillator has a spring constant of 29.9 N/m. While oscillating, it is found to have a speed of 2.53 m/s as it passes through its equilibrium positio
