Answer 1

The AM radio station broadcasting with a power of 61 kW at a frequency of 920 kHz has a power output in watts of 61,000 watts, as one kilowatt is equivalent to 1,000 watts.

Step-by-step explanation:

The power of the AM radio station that broadcasts with a power of 61 kW at a frequency of 920 kHz, in watts, is 61,000 watts. The unit 'kW' stands for kilowatt, and one kilowatt is equivalent to 1,000 watts. Therefore, to convert kilowatts to watts, you multiply the number of kilowatts by 1,000.

In mathematical terms:

61 kW × 1,000 = 61,000 watts

So, the correct answer to the question is option 1) 61,000 watts.
