Question about Plasma Ball (can I leave it running all night?)

AI Thread Summary
Leaving a plasma ball on all night is generally not recommended, as many users report that theirs burned out after extended use. The devices are often cheaply made and may not withstand prolonged operation. It is advisable to turn off the plasma ball when not in use to avoid potential damage. Higher quality versions may be available from specialized suppliers, which could offer better durability. Overall, caution is advised regarding continuous use of plasma balls.

Mine too!
Probably best to have it turned off when you are not watching it. These things are mostly cheaply produced and should be treated accordingly. There may be high quality versions available - perhaps from theatrical lighting suppliers who have to sell stuff that works for ever.
 
Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario
This has been discussed many times on PF, and will likely come up again, so the video might come handy.
