The bare wires that have electricity flowing through them that could kill or seriously injure a person.
The relationship between velocity (v), wavelength (w) and
frequency (f) is expressed as:
v = w f
Plugging in the given values into the equation:
v = 0.643 m (3.25 e 10 Hz)
Where Hz = 1 / s , therefore:
v = 0.643 m (3.25 e 10 / s)
v = 2.09 <span>e 10 m / s</span>
What’s the question? I may be able to help
Orbit circumference
<span>= 2 pi *1.9*10^7 miles </span>
<span>time for orbit trip = 2.9*10^7 s </span>
<span>speed = 2 pi *1.9 / 2.9 miles/second </span>
<span>= 4.12 miles/second </span>
<span>You did not say what units </span>
<span>in miles per hour, multiply by 3600 and get </span>
<span>14,820 miles/hour</span>
The speed of the wave is given by Distance divided by time.
Speed = 10.9/5.1
= 2.14 m/s
But; speed is also given by frequency multiplied by wavelength
Wavelength is 4 m( distance between two successive crests)
thus; 2.14 = 4 × f
f = 2.14/4
= 0.535 Hz
