When the mass of Earth doubles, acceleration due to gravity doubles as well.
Apply Newton's second law of motion;
F = mg --- (1)
where;
F = GmM/R² --- (2)
Solve (1) and (2)
mg = GmM/R²
g = GM/R²
when the mass of Earth doubles, acceleration due to gravity becomes;
g' = G(2M)/R²
g' = 2(GM/R²)
g' = 2g
Thus, when the mass of Earth doubles, acceleration due to gravity doubles as well.

Answer:
Explanation:
a) R = V/I = 0.7/0.022 = 32Ω
b) R = V/I = 0.6/0.005 = 120Ω
c) No...Current change is not linear with voltage change.
