Hi there! :)
In the solar system, we can categorize the planets as such:
Inner planets: Mercury, Venus, Earth, Mars
Outer planets: Jupiter, Saturn, Uranus, Neptune
The Inner planets are the only planets that consist of solid rock. They also do not have rings and have impact craters due to their early formation.
In comparison, all of the outer planets are primarily made up of gaseous material and contain rings.
Therefore, the correct choice is B.
I believe the correct answer is B

Answer:
λ = 
Explanation:
Using the De Broglie equation, the characteristic wavelength is given by:
λ = 
where
h = Planck's constant = 
Js.
p = momentum
Momentum, p, can be calculated using:
p = 
where
m = mass of the electron = 
kg
E = Energy of the electron = 13.4 keV = 
J = 
J
=> p = 
p = 
p = 
kgm/s
Therefore, characteristic wavelength, λ, is:
λ = 
λ =
