D. How the pull of gravity has changed.
Answer:
D
Explanation:
Scientists always perform tests and observe and measure in the physical world to prove their points or answer their questions.
Answer:
height(h)=10 m
acceleration due to gravity (g)=10 m/s^2
mass (m)=?
potential energy=67
or,mgh= 67
or,m×10×10=67
or,m=67/100
or,m=0.67 kg
Therefore,m= 670 grams
