B) A planet's speed as it moves around the sun will not be the same in six months.
Explanation:
A planet's speed as it moves around the sun will not be the same in six months, is a statement that CANNOT be supported by Kepler's laws of planetary motion.
The statement ‘A planet's speed as it moves around the sun will not be the same in six months’ cannot be supported by Kepler’s law of planetary motion.
Answer: Option B
<u>Explanation:
</u>
Johannes Kepler stated three significant laws related to planetary motion. The option A statement is true. Because, the first law defines that the distance between the planet and the sun will not be same as they are rotating around the sun in elliptical orbits.
The third law states that the ratio of square of time taken to complete one orbital rotation by two planets will be equal to the ratio of cube of the distances of the two planets from the sun.
So, according to third law, the statements (c) and (d) can also be supported by Kepler's law. Hence, option (b) is not supported by Kepler's law.
The sum of the potential energy and kinetic energy of a body or system An example of mechanical energy is the power of a football flying through the air.
