A takeout CD contestant requires 12V on control correctly. A transformer nicely allows the figure to be supercharged from a 129-V outlet. If the direct has 500 turns, exhibit that the alternative should hit 50 turns.

A takeout CD contestant uses a underway of 6.8 mA at a possibleness disagreement of 3 V. (a) How such forcefulness does the contestant ingest in 41 minutes? (b) Suppose the contestant has a accumulation of 0.65 kg. How some transactions should the contestant control on so that the forcefulness crapper displace the CD contestant finished a peak of 1m?
(a) Energy exhausted in 41 transactions is J.
(b) The instance for the CD contestant is minutes.
I am extremely intense with physics so along with an explanation, and respond would be such appreciated! Thanks!
