24. a 50-turn coil has a diameter of 15 cm. the coil is placed in a spatially uniform magnetic field of magnitude 0.50 t so that the face of the coil and the magnetic field are perpendicular. find the magnitude of the emf induced in the coil if the magnetic field is reduced to zero uniformly in (a) 0.10 s, (b) 1.0 s, and (c) 60 s.

0.1 = 4.42v

1.0 =0.44v

60 = 7.4 × 10^-3 V

Explanation:

Apply the formula of:

Emf = (No of turns × magnetic flux)÷(the given time)

Where your magnetic flux = (0.50 × cross sectional area(pi × 0.075^2))

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
