Answer: I am pretty sure that you should pick radio waves.
Explanation: The scientist should use radio waves. I think this because you can use the radio waves to analyze the signals from outer space. This will work much better than anything there, to analyze it the best possible.
The best I could do.
Answer:
The energy level is 5.
Explanation:
Given that,
n = 3
l = 2
We know that,
l shows the number of sub-shells and define the number of angular nodes.
n shows the number of electron shell.
is a quantum number. It is define the number of energy level in a sub-shells .
is define the spin of the electron.
So, The quantum number is

is
and
for every energy level.
The energy level is 5.
Hence, The energy level is 5.
Answer:
2.4086 * 10^(-4) m^3
Explanation:
Volume of sphere = 4/3 * pi * r1^3
Volume of cylinder = pi*r2^2*h
r1 = 0.05 m
r2 = 0.03 m
Hence,
Resulting Volume = Volume of sphere - Volume of cylinder
