Answer 1

Answer:

Explanation:

The distances of two planets (Neptune and Saturn) from Sun are 10^13 and 10 ^12 m respectively. The ratio of time periods of revolution around sun for the planets is : 1: 100. 2: 1/√10.

Answer 2

Hҽყα

ᴛʜᴇ ᴀɴꜱᴡᴇʀ ꜰᴏʀ ʏᴏᴜʀ Qᴜᴇʀʏ ɪꜱ:-

Distance of two planets from sun, r1 = 10^13m and r2 = 10^12m.

The Relation between time period (T) and distance of the planet from the sun is T2 ∝ r3  or T ∝ r3/2.

Therefore T1/T2 =

= (r1/r2)^3/2 

= (10^13/10^12)^3/2 

= 10^3/2

= 10√10.
