Answer:
2.14 s
Explanation:
The period is the time for 1 revolution. If it takes 21.4 seconds to make 10 revolutions, then it takes 2.14 seconds to make 1 revolution.
You can show this with a proportion:
t / 1 rev = 21.4 s / 10 rev
t = 2.14 s
Water diffusion is called osmosis. Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.
The gravity of the Sun keeps the planets in their orbits rotating. The same as the Moon orbits the Earth because of the pull of earth's gravity, the earth orbits the Sun because of the pull of the Sun's gravitational pull.
Any questions please feel free to ask. Thanks
Answer:
As we know that science is based upon logic. So the scientific theories have a logical reasoning behind them. So considering that in mind, scientific hypothesis include the motion of sailing rocks by animals, wind, flowing water, magnetic field, humans and gravity. The motion of the rocks by ghosts, God and magic are not scientific theories as we can not prove them logicaly.
Explanation:
Temperate I'm not sure, cuz polar is like freeze, and tropical is hot
