Wavelength = (speed) / (frequency)
Wavelength = (300 thousand km per second) / (10.5 billion per second)
Wavelength = (300 / 10.5) (thousand km per second) / (billion per second)
Wavelength = (28.57) (million meters / second) / (thousand million / second)
Wavelength = (28.57) (meters / second) / (thousand / second)
Wavelength = (28.57) (meters / thousand)
<em>Wavelength = (28.57) (millimeters) </em>

Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material

The first question has the answer to your problem! I found the answer key!
Answer:
s = 3.84 x 10⁸ m
Explanation:
The distance traveled by an object, while in uniform motion, is given by the following equation:
s = vt
where,
s = distance covered
v = speed
t = time interval
In this case:
s = distance between Moon and Earth = ?
v = speed of radio waves = 3 x 10⁸ m/s
t = time taken to travel = 1.28 s
Therefore,
s = (3 x 10⁸ m/s)(1.28 s)
<u>s = 3.84 x 10⁸ m</u>
