Answer:
False
Explanation:
Only one of the two are true. Works in the public domain have a copyright that has expired only. E.g. Works of classical music artist, are almost always expired, in accorance with American Copyright law. Abandoning a copyright doesn't do anything because so long the copyright has remained unexpired, the copyright remains. Thats why it can take decades for a new movie in a series to release, like "IT" by Stephen King. The copyright hasn't expired but rather was 'abandoned'. Before "IT" 2017 was relasesed, the copyright was abandoned.

Answer:
- <u>1,000W</u> (rounded to one significant figure)
Explanation:
I will answer in English.
The question is:
- <em>What is the power of a filament lamp that connects to the 220 V network, knowing that it has a resistance of 50 ohms?</em>
<em />
<h2>Solution</h2>
<em />
<em>Power</em>, <em>voltage</em>, <em>resistance</em>, and current, are related by either of the following equations:
Where:
- R is resistance in ohms (Ω)
- V is voltage in volts (V), and
- I is current in amperes (A)
Since you know the voltage (<em>220V</em>) and the resistance (<em>50Ω</em>), you can use the last equation:
Since the magnitude 50Ω has one significant figure, your answer should be rounded to one significant figure. That is <u>1,000W.</u>
