Question

write the expression for kepler's third law​

Answer 1

Answer:

Kepler's third law can be represented symbolically as P2∝a3, where P is the orbital period of the planet and a is the semi-major axis of the orbit (see. ... After substituting an expression for the velocity of the planet, one can obtain: GMr=4πr2P2 which can also be written P2=4π2a3GM

Answer 2

Answer:

• The square of the period of a planet's orbit is proportional to the cube of its semi-major axis .
