We know, density = mass /volume
Here, m = 10 g
v = 2.5 mL = 2.5 cm³
Substitute their values,
density = 10/2.5
<span>d = 4 g/cm³
</span>
In short, Your Answer would be <span>4 g/cm³</span>
Hope this helps!
Answer is 6.84 approx
reason:-
(2.78^2+6.25^2)^1/2=6.84 approx
This question involves the concepts of the law of conservation of momentum.
The magnitude of the final momentum of the eight ball is "0.22 N.s".
According to the law of conservation of momentum:
where,
= initial momentum of the cue ball = 0.23 N.s
= initial momentum of the eight ball = 0 N.s (since ball is initially at rest)
= final momentum of the cue ball = 0.01 N.s
= final momentum of the eight ball = ?
Therefore,

Do you not understand how to solve for the answer?
False. What actually determines the properties of elements are the electrons, or aka valence electrons. They are used to bond, which determines its properties.
