Answer:
h2 = 0.092m
Explanation:
From a balance of energy from point A to point B, we get speed before the collision:
Solving for Vb:

Since the collision is elastic, we now that velocity of bead 1 after the collision is given by:

Now, by doing another balance of energy from the instant after the collision, to the point where bead 1 stops, we get the distance it rises:
Solving for h2:
h2 = 0.092m
We have discovered 786 planets. Most of which were only recently discovered.
No
For example a rock was broken into one big and one little piece. The properties of these 2 pieces are still the same even though they have different shapes.
Offspring get two alleles for each trait – one from each parent.
