Answer:
It is longer
Explanation:
According to the theory of special relativity, moving clocks run slower. So, the construction worker moving at a constant speed observers a time much longer than the time I observe since I am stationary. If t is the time observed by me and v is the speed of the construction worker, then, the time observed by the construction worker, t' is given by
t' = t/√[1 - (v/c)²] where c = speed of light
So, the construction worker reports a longer time interval than me since his time runs slower.
A). period is time
b). amplitude can be almost anything that waves . . . length, voltage, pressure, current etc.
But not hertz.
c). frequency ... "oftenness ... reciprocal time. the only item on this list that CAN be measured in Hertz.
d). wavelength ... length units
Quick definition: fear appeal: making someone do something out of fear of something.
I think the way it's used is that doctors make people dear disease.
