You wouldn't know it from reading the question,
but the volume of a sphere is
4/3 π (radius)³ .
So the volume of Saturn is
(4/3 π) (6.03 x 10⁷ m)³ = about 9.184 x 10²³ m³
and its density is (mass) / (volume)
= (5.68 x 10²⁶ kg) / (9.184 x 10²³ m³)
Sadly, we need this to be in units of ' gram/cm³ ' so we need to
account for some conversion of units.
= (5.68 x 10²⁶ kg) · (1,000 g/kg) / (9.184 x 10²³ m³) · (10⁶ cm³/m³)
= (5.68 x 10²⁹ grams) / (9.184 x 10²⁹ cm³)
= 0.618 gram/cm³ .
Look at that !
The density of the planet Saturn is less than ' 1 '.
If you had a big enough bathtub full of water, Saturn would float in it !
The surface area of a sphere is
4 π (radius)²
= (4 π) (6.03 x 10⁷ m)²
= (4 π) (36.4 x 10¹⁴ m²)
= 4.57 x 10¹⁶ m²

Answer:
432 J
Explanation:
When moving linearly:
Kinetic Energy = (1/2)mV^2
So here you have:
KE=(1/2)(6)(12^2)=(1/2)(6)(144)=432
The unit for energy is Joules (J), so your answer would be 432 J.
