Answer:
The length of AB is 7.45 units.
Step-by-step explanation:
You can find the length of AB using Cosine Rule, cosθ = adj./hypo. :
θ = 20°
adj. = 7 units
hypo. = AB
cos 20° = 7/AB
AB = 7/cos 20°
= 7.45 units (3s.f)
We simply divide the mass of Saturn with the mass of Earth.
5.686 x 10^26 / 6.04 x 10^21
The rule of significant figures when dividing numbers is that the least amount significant figures must be used in the quotient.
Therefore, Saturn is 9.41 x 10^4 times heavier than Earth.
