Answer:
hi dear, the answer is option D, {-8,2}
Answer:
2440 km; 1.330 × 10²⁷ kg
Step-by-step explanation:
(a) <em>Radius of Mercury
</em>
D = 4.88 × 10^³ km
D = 2r Divide each side by 2
r = D/2
r = (4.88 × 10³)/2
r = 2.44 × 10³ km Convert to decimal notation
r = 2440 km
(c) <em>Mass difference
</em>
Difference = 1.898 × 10²⁷ - 5.68 × 10²⁶ Rationalize exponents
Difference = 1.898 × 10²⁷ - 0.568 × 10²⁷
Difference = 1.330 × 10²⁷ kg
