Answer:

T2 = 1680,4 days

Explanation:

Kepplers law:

[tex]\frac{T^{2} }{a^{3} } = constant[/tex]

For Earth:

T1 = 365 days ; a1 = 149 597 870 700 m

For Ceres:

T2 = ? days ; a1 = [tex]414*10^{9} m[/tex]

Then:

[tex]\frac{T1^{2} }{a1^{3} } = \frac{T2^{2} }{a2^{3} } ----> T2 = T1*\sqrt{\frac{a2^{3}}{a1^{3}}}[/tex]

Replacing values:

T2 = 1680,4 days

Answer:

Answer is 1.156x10^23 sec

Explanation:

According to kepler's law, the square of the period of revolution is proportional to the cube of the distance within planets.

At a distance r of 414 million kilometers I.e 414x10^6 km, period calculation is shown in the image below.
