← ScienceWhich time keeping outcome occurs when comparing ground and high GPS satellite clocks?
A)Satellites' clocks fall behind because equivalence.
B)Ground clocks speed up because motion effects.
C)Satellite clocks speed up because gravitation.✓
D)Ground clocks slow down because radio interference.
💡 Explanation
Satellite clocks run faster due to less gravitational time dilation because of general relativity's principle of equivalence; therefore, the satellite's clock speeds up, rather than slowing down or clock changes by motion effects.
