A flat coil of wire consisting of 16 turns, each with an area of 50 cm2, is positioned perpendicularly to a uniform magnetic field that increases its magnitude at a constant rate from 2 T to 7 T in 2.0 s. What is the magnitude of the emf (in Volts) induced in the coil? Your answer should be a number with two decimal places, do not include the unit.

The  value is  

Explanation:

From  the question we are told that

 The number of N  =  16 turns  

  The area is  

  The initial  magnetic field is  

   The  final  magnetic field is

   The time taken is  

Generally the magnitude of the emf is mathematically represented as

=>    

=>    

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
