Answer:
All the predictions in the impact theory are true.
Explanation:
That’s because of their predictions. Modern computer simulations predict that there happened a collision between Earth and a planet named as Theia. The chunks of both planets conformed into a stable orbit and form the satellite that we know today as our Moon. Similarly, both moon and Earth share similar mantle compositions but cores are dissimilar in terms of their size and composition.
Radio waves are used in cell phone wireless communication by this: Radio waves are released from the cell phone and travel to satellites in the stratosphere. After they reach the satellite, they are redirected to the recipient of the call/text.

Explanation:
Using,
S = vi*t + 1/2*a*tr^2
vi = initial velocity = 0 m/s
S = 1/2 * 9.8 * tr^2
= 4.9tr^2.
S = vf * (ta - tr)
4.9tr^2 = 330 * (9.3 - tr)
4.9tr^2 - 3069 + 300 * tr)
Using general quadratic equation,
tr = 8.93 s.
S = 4.9 * (8.93)
= 390.75 m.
B.
Therefore,
S = 4.9 * (9.3)^2
= 423.8 m.

Wavelengths of light are emitted when an electron is coming from an energized state back to its initial state. The energy that is omitted comes in the form of the wavelength. I'm not completely sure if this is totally the way to say it, but it is what I remember from chem last year.
