Why is the wave energy lower when it reaches the receiver? (Hint: think about what you know about visible light.)

There are two reasons. First, the wave spreads out as it moves away from the transmitter, which reduces its energy over a given area. Second, some energy is absorbed by the air.

Explanation:

the increase of protons   hope this

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
