The relationship between speed of a wave w, frequency f and wavelength
is
For the wave of our problem,
and f=60 Hz, so its speed is
<span>1. It must be an object which independently orbits the Sun (this means moons can't be considered planets, since they orbit planets)
2. It must have enough mass that its own gravity pulls it into a spheroidal shape.
3. </span><span>It must be large enough to "dominate" its orbit (i.e. its mass must be much larger than anything else which crosses its orbit).</span>
Wave D has the same wavelength as wave A, but the amplitude is lower. The answer is Wave D.
