Mercury has less mass than earth. So the answer is B
This is a question that would have literally have taken two seconds to look up on google but the answer is 1.88 years.
The formula is:
Work = Force · Displacement
F = m · g
F = 16 kg · 9.8 m/s² = 156.8 N
and we know that:
d = 0.8 m
W = 156.8 N · 0.8 m = 125.44 J
Answer:
W = 125.44 J.
