Correct answer is "frequency", not "hertz"

jerrevd is correct:
Frequency — The number of cycles per second. Measured in Hertz. If a current completes one cycle per second, then the frequency is 1 Hz; 60 cycles per second equals 60 Hz.
Hertz is a unit of measurement.

Frequency is the rate at which something occurs or is repeated over a particular period of time or in a given sample. It is not the rate at which something occurs "per second" unless further explained as such. If you read the question It specifically calls out a defined time of one second. Were frequency can be expressed in any amount of time. EX: the frequency of (cycles per min) equals 3600. the frequency of (cycles per second) equals 60.
My point is the denominator when defining frequency is a variable not one second. The denominator in the unit Hz is defined as one second.

Power Produced in one complete cycle

Hi,
I hope you are doing well. I am curious to know, how much power does a 2.5MW turbine would produce in one complete cycle? Will it be equal to 2.5MW?

A ideal turbine running at 100% producing 2.5M W for one cycle at 60Hz. 2500000 ÷ 216000= 11.57407 watt hours or 0.01157407 KWh. KWh is a common for expressing power over time. But it could be expressed as Watt (any measure of time).

Thats not why you asked that tho is it. Were you making a point about cycles and frequency?

Given that the question ends with the statement "the," it wouldn't make sense to say "the hertz" as it would to say "the frequency." Try not to overthink the question and go with what makes sense.

Why you divided it by 216000? I mean it is what quantity?

You asked a question about power over time. 60Hz = 60cycles per second. 60 seconds in one min 60 min in one hour. 60X60X60 = 216000 cycles per hour. So 2.5 MW for one hr = 2500 KWH. Divide that by 216000 gives you KW for one cycle at 60Hz.
