The flash unit in a camera utilizes a 9.0V battery to charge a capacitor. The capacitor is then discharged through a flash lamp. The discharge takes 10s, and the average power dissipated in the flash lamp is 10 W.
A 2 kilogram mass is released from rest and slides down an inclined plane of 60o a distance of 1 m. It strikes a 250 N/m spring. Evaluate what is the maximum compression of a spring
A very long, straight wire carries a current of 0.180 A. This wire is tangent to a single-turn, circular wire loop that also carries a current. The directions of the currents are such that the net magnetic field at the center of the loop is zero.
