Frequency of any wave = (the wave's speed) divided by (its wavelength)
Speed of light = about (3 x 10 to the 8) meters per second, in vacuum.
Frequency = (3 x 10 to the 8) / (4.1 x 10 to the -12) = 7.317 x 10 to the 19 Hz.
That's the same as 73,170,000,000 GHz.
Note:
That's the answer for the information given in the question, but the information in
the question is incorrect by 5 orders of magnitude. The wavelength of violet light,
or anything in the visible range, is a few hundred 'nanometers' ... a few hundreds
of 10 to the -9 . So the number in the question should be 4.10 x 10 to the -7,
not -12, and the frequency should be 731,700 GHz.
1 yard^2 = 0.8361m^2.?
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
<span>So he spent (.625 x 400) = $250.00 per m^2. </span>
<span>He paid out (500 x 250) = $125,000 on the deal. </span>
<span>He received (500 / 0.8361) = 598.014592 yard^2 of fabric. </span>
<span>That would have cost (598.014592 x 120) = $71,761.75 locally. </span>
<span>He lost (125,000 - 71,761.75) = $53,238.25 on the deal. </span>
You can rework with the incorrect conversion factor.
Answer:
Explanation:
We are given that
Frequency,f=800KHz=
Distance,d=4.5 km=
1 km=1000 m
Electric field,E=0.63V/m
We have to find the magnetic field amplitude of the signal at that point.
We know that
She can first measure the mass on the scale, then measure the cm^3 by putting water in the cylinder and measuring the original water level minus the water level after you put the rock in. The take the measurement from the scale (g) and divide it by the measurement in the graduated cylinder (c^3).
