Answer:first law
Explanation:
it states the a body in motion or rest maintain its state until an external force is acted on it
F = ma
a = f/m
if f doubled , acc. will be doubled
C Camera. I think this because you can make timelapses with cameras which makes it easy to see.
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.
Average acceleration: velocity/time
5/4= 1.25 m/s² Acceleration
Hope I helped :)
