Answer:

Explanation:

Saturn orbital period

p(s)= 29.46years

Average distance

a(s) = 9.54AU

Venus orbital period

p(v) = 0.62 years

a(v) ?

Using Kepler's third law

a³ ∝p²

a³ = kp²

a³/p² = k

Where

a is the distance if planet from sun

T is the period of the planet

Then,

a(Venus)³/p(venus)² = a(saturn)³/p(saturn)²

a(v)³/p(v)² = a(s)³/p(s)²

a(v) ³/ 0.62² = 9.54³/29.46²

a(v) ³/ 0.62² = 1.0004

a(v)³ = 1.0004× 0.62²

a(v)³ = 0.3846

a(v) = cube root(0.3846)

a(v) = 0.727 AU

Answer:

15.66 AU

Explanation:

Using Kepler's law which states that T² ∝ R³ where T = period of planet and R = distance of planet from sun.

So T₁²/T₂² = R₁³/R₂³

where T₁ = orbital period of Saturn = 29.46 years

           T₂ = orbital period of Venus = 0.62 years

           R₁ = average distance of Saturn to the sun = 9.54 AU

           R₂ = average distance of Venus to the sun = ?

From the equation above,

R₂³ = (T₂²/T₁²)R₁³

R₂ = [∛(T₂/T₁)²]R₁

R₂ = [∛(0.62/29.46)²]9.54 AU

R₂ = [∛(0.021)²]9.54 AU

R₂ = [∛0.000443]9.54 AU

R₂ = [0.0762]9.54 AU

R₂ = 0.727 AU
