eagle eyes are about 100 times better than ours, they can "zoom" in with their eyes too.
yes, with their eyes closed!
Frequencies higher than 60Hz are frequently used. Although there are radio waves lower than 60Hz, all of our radio transmissions are well above that. If you mean why frequencies for mains power supply above 60Hz can't be used, the answer is, they can. The higher the frequency though, the higher the loss although this doesn't really come into play until frequencies above several hundred Hz are used. 50Hz or 60Hz were chosen originally because of the mechanical nature or early generators.
yes it is better when you see with two eyes then one because when you cover your eye with your hand you dont see that clearly as when you two eyes
yes
Because it has two eyes (two I's).
