Well, one of the theories was that Charles darwin proved that theory evolution is real so that one theory.
Answer:
Left to right and top to bottom
Explanation:
On the periodic table, the properties repeat from left to right and from top to bottom.
Periodic properties have a pattern from the top to the bottom or down a group or family.
Also, across the period from left to right, they also show a repeating pattern.
- Certain properties increase from left to right and decreases from top to bottom. E.g. electronegativity.
- Also, some properties decreases from left to right and increases from top to bottom e.g. atomic radius.
The conservation of energy always holds true even when not clearly observable in machines that are less than 100% efficient. More often than not a machine will suffer energy losses (e.g. consider for a cooling fan: friction between the rotating blades, drag resistance in the air the fan is pushing around, resistance in the wire, and heat radiating/conducting away from the circuitry).
Time = (distance) / (speed)
Time = (180 miles) / (60 mi/hr)
Time = (180/60) (mi-hr/mi)
<em>Time = 3 hours</em>
According to wikipedia <em>a mid-ocean ridge is an underwater mountains system formed by tectonic plates.
