Answer:
b. 48.0 g.
Explanation:
Given;
mass of the exoplanet,
radius of the exoplanet,
The acceleration due to gravity of the planet is calculated as;
Therefore, the correct option is b. 48.0 g
A. Molecular solids tend to have lower melting points than Ionic so it would be Ionic if it weren't for Molecular.
Answer:
398.0 N = 89.74 pound force
Explanation:
Gravitational force:
R = 6371 km (Radius of the Earth)
At the surface, weight of the surface w =220 pounds = 978.61 N
2250 miles = 3621024 m
total distance from the center of the Earth
3621024 m + 6.371×10⁶ m = 9.99×10⁶ m
398.0 N = 89.74 pound force
