Question

1. evidence

select two statements that count as evidence supporting whether mnca25 follows
kepler’s laws of planetary motion

hint: evidence is scientific data (numbers, observations, or measurements) that
supports the claim.

(2 points)

the laws of physics are universal and apply everywhere in the universe.

mnca25 follows kepler’s laws of planetary motion, just like planets in our solar system.

mnca25’s orbital eccentricity is 0.04, showing it has an almost circular orbit.

mnca25 travels 31.2 km/s when closest to its star and 28.7 km/s when farthest away.

Explanation:

To determine evidence for MNCA25 following Kepler’s laws, we need scientific data (measurements/observations).

1. "The laws of physics are universal..." is a general statement, not specific data about MNCA25.
2. "MNCA25 follows Kepler’s laws..." is a claim, not evidence.
3. "MNCA25’s orbital eccentricity is 0.04..." provides a measurement (eccentricity) related to Kepler’s 1st law (orbital shape), so it’s evidence.
4. "MNCA25 travels 31.2 km/s... 28.7 km/s..." provides speed measurements at different orbital points, related to Kepler’s 2nd law (equal area in equal time, implying speed changes with distance), so it’s evidence.

Answer:

• MNCA25’s orbital eccentricity is 0.04, showing it has an almost circular orbit.
• MNCA25 travels 31.2 km/s when closest to its star and 28.7 km/s when farthest away.
