A. periodically reversed directions as magnetic polarity reversals show
B. constant over entire history of solar system
C. speeding up very gradually due to Moon's influence
What is the resolving power of the telescope?
A. ability to make distant objects appear closer
B. ability to separate light into its component colors
C. ability to distinguish adjacent objects in the sky
In order to determine mass of planet by applying Newton's laws of motion/gravity, the planet must have
A. Rings
B. Moons
