The force of gravity on mars is 0.38 times the gravity on earth. the mass of an
object on earth is 71 kg.
what are the mass and weight of that object on mars?
a. mass: 71 kg, weight: 710 n
b. mass: 71 kg, weight: 270 n
c. mass: 27 kg, weight: 270 n
d. mass: 27 kg, weight: 103 n

the answer is B

Explanation:

because the mass of any object is constant anywhere so the mass of the object on earth =the mass of the object on mars or any other planet=71kgwhile the weight=massxgravity since the gravity on earth=10m/s^2 and the gravity on mars =0.38x10=3.8m/s^2then the weight =71x3.8=269.8"approximately270N"
