one solenoid is centered inside another. the outer one has a length of 45.0 cm and contains 6800 coils, while the coaxial inner solenoid is 4.00cm long ans 0.120 cm in diameter and contains 21.0 coils. the current in the outer solenoid is changing at 35.5 A/s.
(a) what is the mutual inductance?
(b) what is the EMF induced in the inner solenoid?
A pipe open at one end has a fundamental frequency of 256 Hz. A second pipe,identical to first pipe, is shortened by cutting off a portion of the open end. When both pipes vibrate at their fundamental frequencies, a beat frequency of 12 Hz is heard..
