B is the best answer. Once the particles are sufficiently close, the strong nuclear force becomes stronger than the Coulomb repulsion and they are pulled together. This results in bound particles that have a binding energy that can be retrieved of you can get the particles far enough away from one another after binding, but this requires large and unstable nuclei (beyond lead on the table) These elements are referred to as radioactive, because they are prone to decaying
The speed of light in glass is slower than the speed of light through space.
a) 14.4 m/s
The problem can be solved by using the law of conservation of total momentum; in fact, the total initial momentum must be equal to the final total momentum:
So we have:
(1)
where
is the mass of each ball
is the initial velocity of the green ball
is the initial velocity of the blue ball
is the final velocity of the green ball
is the final velocity of the blue ball
Simplifying the mass in the equation and solving for , we find
b) 12.0 m/s
This time, the green ball continues moving after the collision at
So the equation (1) becomes
And solving for we find
c) 13.5 m/s
This time, the green ball continues moving after the collision at
So the equation (1) becomes
And solving for we find
Answer:
NEW
Explanation:
As the moon moves to position Z it becomes a New moon due to the light of the sun shining on it
Ordinary cells can convert chemical energy to electrical energy only, but rechargeable cells can also store electrical energy into chemical energy and vice versa. You will study more about it in your higher classes. secondary cells can be recharged and used again but dry cells cannot be recharged.
