Explanation:
Scientists collect data for decades after Apollo 11's return to earth. Finding include that the moon is moving farther away from earth and that the universal force of gravity is stable.
1.12 m/s is the velocity. You can get the velocity of a wave by multiplying the frequency and wavelength together. The product is the velocity.
True. If the amount displaced is more than the mass, it floats. If the amount is less than the mass, it will sink.
The Photosphere is the right answer
