100 MHz = 100,000,000 Hz = 10^8<span> Hz
And using basic conversions between frequencies, I've determined that the wavelength is roughly 3 meters.</span>
All you have to do is add 600 + 1,400 which = 2,000
So your answer is D) 2,000 J
I hope this helps. :)
I had the same test btw
Answer:
Magnitude of the horizontal force applied = 120N
Explanation:
The explanation and the FBD - free body diagram is shown in the attachment
From F = Miu(R)
Wavelength = (speed) / (frequency)
= (3 x 10⁸ m/s) / (1 x 10⁸ /s) = 3 meters
