Answer:
AM radio = 540 - 1650 KHz
FM radio = 88 to 108 MHz
Television = 54 to 216 MHz
Answer:
114.92749 keV
Explanation:
r = Radius of trajectory
m = Mass of electron = 
B = Magnetic field = 0.044 T
q = Charge of electron = 
The centripetal force and the magnetic forces are conserved

Velocity of first electron

Velocity of second electron

Total kinetic energy is given by

Converting to eV


The energy of incident electron is 114.92749 keV
<em>Soil can be described as the C. Loose covering of weathered rocks and decaying organic matter.</em>
I believe it’s B. Electrons
I’m so sorry, I need more information. Good luck and I’m sorry I couldn’t help you :(
