Answer:
The right answer is atmospheric nitrogen→bacteria→plants→animals
Answer:
Average speed = (total distance covered) / (time to cover the distance)
You only need the first and last points from the table.
First point: Position=0, Time=0
Last point: Position= 16.34, Time = 2.34 hours
Total distance covered = 16.34 (miles ? km ?)
Time to cover the distance = 2.34 hours
Average speed = (16.34 miles) / (2.34 hours)
Average speed = 6.983 mile/hour

Question:
How do rechargeable batteries work?
Answer:
When a rechargeable battery is connected to electricity it changes the pressure inside and allows the rubber membrane to expand, thus releasing more energy next time its used. When plugged into the wall the electrons are sent back to rebuild the original dry cell (or metal). Rechargeable batteries are made exclusively of nitrogen which when exposed to electricity from and outlet can store a charge. When a battery is zapped by the electricity from the outlet it resets the system.
Answer:
160m/s
Explanation:
The speed of a wave is related to its frequency and wavelength, according to this equation:
v=f ×λ
