What is the best shape through which we can model the path of a celestial body?
A sphere with the center of motion away from the shape’s center
An oval
An ellipse
A perfect circle
Is it possible to measure the absolute energy in a system?
No, as it is impossible to comprehensively account for every joule in the body
No, as it is extremely cumbersome to account for every single molecule and atom in the body
Yes, as bodies are not that large to measure energy for.
No, as energy is a vector.
Is it possible to measure both the position and momentum of a particle, at an atomic scale, at the same time?
Not quite, although we can within a certain extent of accuracy.
Not at all, owing to the untraceable velocity of electrons.
Yes, as position and momentum both depend on the velocity of the electron.
No, as electrons only absorb, but do not emit enough light to allow us to even vaguely determine their location.
What is the value of the speed of light?
3 x 10^8
299,792,458 mi/s
299,792,458 m/s
300 miles per millisecond

The element has enough electrons
Which is the best answer for why atomic radius decreases as you go across the periodic table?

The mass increases
Ionization energy increases
The atomic number increases
