30s - Q6
What will happen if the antenna of the analog television is placed inside the house?
Pictures and sound transmitted are strong due to its enclosed location.
Pictures are clear, but the sound is intermittent due to its enclosed location
Pictures are blurred, but the sound is good due to the transmitter’s location
Pictures and sound transmitted are weak due to the location of the transmitter
30sS10FE-IIc-d-48 - Q7
Which is NOT included in the group for radio communication?

30sS10FE-IIe-f-49 - Q13
What does ionizing radiation remove from atoms?
electrons
nucleus
neutrons
protons
30sS10FE-IIe-f-49 - Q14
What is the difference between ionizing and non-ionizing radiation?
Ionizing radiation is a naturally occurring phenomenon and non-ionizing radiation is only created artificially
Non-ionizing radiation is a naturally occurring phenomenon and ionizing radiation is only created artificially
Ionizing radiation has high energy that can remove an electron from the atom, but non-ionizing does not.
Non-ionizing radiation is high energy radiation, but ionizing radiation is low energy radiation.
30sS10FE-IIe-f-49 - Q15
