Storyline. In the Blue Ridge Mountains of Virginia, during the Great Depression, the Walton family makes its small income from its saw mill on Walton's Mountain. The story is told through the eyes of John Boy, who wants to be a novelist, goes to college, and eventually fulfills his dream.
The SI unit for period is the second. For counts per unit of time, the SI unit for frequency is hertz (Hz), named after the German physicist Heinrich Hertz; 1 Hz means that an event repeats once per second.A previous name for this unit was cycles per second (cps).or each dot, f is the frequency in hertz (Hz) â meaning the number of times per second (i.e. cycles per second) that it flashes â while T is the flashes' period in seconds (s), meaning the number of seconds per cycle. Each T and f are reciprocal.
Best Answer: The period, T, is the time required for one complete cycle and the unit is seconds. The equation for period is: T=1/frequency The frequency is the number of complete cycles in one second and the unit is Hz or S^-1 So T= 1/25.0Hz, T= 0.04 seconds.Source(s): Jenn26 Â· 7 years ago.Thumbs up.ind the following values for this wave: a) Period (Hint: frequency is given) b) Speed I know... show more Waves and Vibrations unit in High School Physics course... -Homework question: A wave with an amplitude of 9 cm and a wavelength of 20 cm is traveling in the positive x direction with a frequency of 25.0 Hz.
