Answer:
The answer is the second option.
Explanation:
This is a higher temperature than Onnes's experiment, and it will allow for a broader use of superconductors.
15.49 should be the answer if that is 12 watt battery.
Potential energy behind dams
Calculate its average speed in meters per second
Answer:
5.77 m/s
Explanation:
Speed= Distance/Time
Distance= 40+ half of 40= 40+20= 60 m
Time= 8.8+1.6=10.4 s
Average speed= 60/10.4=5.769230769 m/s
Approximately, the average speed is 5.77 m/s
