The rms current in a copy machine is 7.10 A, and the resistance of the machine is 24.50. What are (a) the average power and (b) the peak power delivered to the machine? (a) Number Units (b) Number Units vA particle of mass 7.1 x 10" kg and charge +9.0 JC is traveling due east. It enters perpendicularly a magnetic field whose magnitude is 3.7 T. After entering the field, the particle completes one-half of a circle and exits the field traveling due west. How much time does the particle spend in the magnetic field? Number UnitsConsult Multiple-Concept Example 11 for background material relating to this problem. A small rubber wheel on the shaft of a bicycle generator presses against the bike tire and turns the coil of the generator at an angular speed that is 48 times as great as the angular speed of the tire itself. Each tire has a radius of 0.261 m. The coil consists of 120 turns, has an area of 3.06 x 1075 m, and rotates in a 0.140-T magnetic field. The bicycle starts from rest and has an acceleration of +0.502 m/s. What is the peak emf produced by the generator at the end of 6.05 s? Number i UnitsTwo parallel plate capacitors are filled with the same dielectric material and have the same plate area. However, the plate separation of capacitor 1 is twice that of capacitor 2. When capacitor 1 is connected across the terminals of an ac generator, the generator delivers an rms current of 0.680 A. What is the current delivered by the generator when both capacitors are connected in parallel across the terminals? Number i Units vThe image produced by a concave mirror is located 25 cm in front of the mirror. The focal length of the mirror is 17 cm. How far in front of the mirror is the object located?
