Answer:
Therefore, the correct option is c: 0.
Explanation:
We can find the speed of the combined object by conservation of linear momentum:
Where:
"i" is for initial and "f" is for final
m₁: is the mass of the first object = m
m₂: is the mass of the second object = 3m
v₁: is the velocity of the first object
v₂: is the velocity of the second object
Therefore, the correct option is c: 0.
I hope it helps you!
I beleive D if this is wrong then it has to be B correct me if I’m wrong
A.
Polarized glasses allow vertical light in, blocking horizontal light so that most of the glare is eliminated.
Answer:
v =
the sppedof the electron is also quantized
Explanation:
The angular momentum of a rotating body is
L = m v r
in Bohr's atomic model the quantization postulate is that the angular momentum is equal to
L = n
we substitute
n = m v r
v =
where n is an integer.
Therefore, the sppedof the electron is also quantized, that is, sol has some discrete values.
Answer:
Explanation:
Given that,
The gravitational force between two electrons is
The electrons are 1 m apart.
The formula for the gravitational force is given by :
Where
m is the mass of the electrons
So, the mass of the electron is .
