Answer:
K
Explanation:
The Heisenberg uncertainty principle is
Δx Δp ≥ h' / 2
h’ =
The kinetic energy of a particle is
K = ½ m v²
p = mv
v =
substitute
K =
from the uncertainty principle,
Δp =
we substitute
K =
Answer:
Explanation:
h = Planck's constant =
K = Potential difference = 50 V
m = Mass of electron =
The de broglie wavelength is given by
The wavelength is
They work on a weightless planet, therefore they have very little muscle control since they float in space !!
The answer is B I hope this helps luv
