Yes. Exactly.
Good work !
100hz means the picture on the tv is refreshed 100 times a second. The higher the hz the more frames per second which results in a smoother video.
Cycles per second is known also known as the frequency. 100 cycles per second is 100 hertz (100hz). I can't answer your question though as there is not enough information. However if it is multiple choice and there is no other info the best answer is one.
186,282.4 miles per second.
Frequency, referring to sound, is the amount of complete waves every second that produce sound. For example: High pitched sounds, like the sound that whistles make, have a high frequency (lots of waves per second). And Low pitched sounds like the sound that a subwoofer makes have a low frequency (Not so many waves per second) The average human can hear from 20hz (cycles per second) up to around 20,000hz (cycles per second)
One Hertz equals one cycle per second.

100 feet per second.
Frequency
Like all light waves, infrared light moves at a speed of 300,000,000 meters per second (186,000 miles per second).
Speed of light = 299,792,458 meter per second = 29,979,245,800 cm per second Wave Length = λ = 4 x 10-5 cm = 4 / 100000 cm. So no of waves passing a point per second = 29,979,245,800 x 100000 / 4 = 749,481,145,000,000 = 74,948 billion waves per second
Hz as a unit of measurement is "cycles per second" 100 Hz is then 100 cycles of the oscillation per second.
It could be metres per second (radio waves), or centimetres per second (microwaves), down to nanometres per second (gamma rays).
