True because if anything is moving it is in motion. And because horizontal is similar to projectile!
Answer:
Polymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer
Explanation:
It's 10.
Mass = density x volume
M = 1g/ml(10ml) = 10g
If you need half the volume, you need double the pressure (V * p). Normal air pressure in the atmosphere is 101300 Pa so that means you need double that, thus 202600 Pa (or 2,026 bars)
