hence, here the distance is 10cm
So the wavelength is 10cm
===> 10 cm
Kinetic Energy I’m not 100% shure tho
Answer:
(you can use my exact words) The length and thickness would make it so that the electrons move differently than they would a shorter and thinner wire because with the wire being longer the electrons would have a longer trip and with the wire being thicker the electrons would be more spread out and move be able to move more freely
Answer:1.37
Explanation:

Let the distance between two points be x


From 1 & 2 we can get
