Amagnetic field of 0.200 t exists within a solenoid of 500 turns and a diameter of 10.0 cm. how rapidly (that is, within what period of time) must the field be reduced to zero if the average induced emf within the coil during this time interval is to be 10.0 kv?

Aform of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space. there are many forms of  electromagnetic  energy including gamma rays, x rays, ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves.

Depending on how the continental plates move it can cause a continental scale shift.
