Question

question 29
which of the following is not a statement of one of keplers 3 laws?
a hot, solid object or a hot, dense gas emits a continuous spectrum.
more distant planets orbit the sun at slower average speeds.
all planets orbit the sun in ellipses with the sun at one of the foci.
as a planet moves around its orbit, it sweeps out equal areas in equal times.

Explanation:

Kepler's laws describe planetary motion. The first law states planets orbit the Sun in ellipses with the Sun at a focus. The second law says a planet sweeps out equal areas in equal times. The third law relates orbital period and distance. The statement about a hot - solid or hot - dense gas emitting a continuous spectrum is related to spectroscopy, not Kepler's laws.

Answer:

A. A hot, solid object or a hot, dense gas emits a continuous spectrum.
