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
Your answer is c. homologous structures
Given: Mass m = 400 Kg; Height h = 3 m; g = 10 m/s²
Required: Work = ?
Formula: Work = Force x distance F = ma a = g F = mg
W = fd
W = mgh
W = (400 Kg)(10 m/s²)( 3 m)
W = 12,000 Kg.m²/s²
W = 12,000 J
