Which of the following describes what will happen if an iron core is inserted into a coil of wire? the wire will have a larger magnetic field. the iron core will become magnetized. the wire will have a smaller magnetic field. the core will become smaller.

If the chemical properties of a substance remain unchanged and appearance or shape of a substance changes it is called a ?

What is the equation for electrical work?

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
