Answer:
The energy used for the 30-day period is 4878000 kilojoules.
Explanation:
According to the power bill, 1355 kilowatt-hours was used over a 30-day period. A kilowatt-hour is equal to 3600 kilojoules. Then, we calculate the energy used, measured in kilojoules, is determined by simple rule of three:
The energy used for the 30-day period is 4878000 kilojoules.
Here's my pick at this:
Entropy (or some form of disorder) will always increase in time.
Thus if you look at snapshots of a system and see that it's entropy is increasing you can tell the flow (or arrow) of time!

Power = (voltage) x (current)
100w = 220v x current
Current = 100w / 220v = <u>0.455 Ampere</u> (rounded)
The acceleration is 3 m/s per minute, or 0.05 m/s per second.
