Nuclear power generates alot of power, ALOT. It requires Uranium and other radioactive substances to power it, which over time can degrade and become depleted. This radioactive waste would have to be placed somewhere, and it accumulates over time slowly.
The atom has 71 protons.
(The atomic number of a chemical element is the number of protons found in the nucleus of an atom)
hope this helps
Answer:
Average speed = 53.33 km/h
Explanation:
Below is the calculation for the average speed:
Given the average speed of for first 40 km = 80km/h
Time taken to cover the first 40 km = Total Distance / average speed
Time taken to cover the first 40 km = 40 / 80 = 0.5 hours
Given the average speed of for next 40 km = 40km/h
Time taken to cover the next 40 km = Total Distance / average speed
Time taken to cover the next 40 km = 40 / 40 = 1 hours
Now the average speed of the tuck to cover total distance:
Average speed = Total distance / Total time
Average speed = (40 + 40) / (0.5 + 1)
Average speed = 53.33 km/h
