Will is a scientist. he’s designing a spacecraft that would allow people to land on mars. will’s mass on earth is 75 kilograms.

will knows that the gravitational pull of mars is less than the gravitational pull of earth. when he lands on mars, his mass will be 1) to 75 kilograms. his weight on mars will be 2) his weight on earth.
a. equal to
b. greater than
c. less than

For 1: the correct answer is Option A.

For 2: The correct answer is Option C.

Explanation: There is a huge difference in mass and weight.

Weight is defined as the force which is exerted on the body by gravity. This term is not a constant term. It is dependent on the value of of acceleration due to gravity. Unit for this term is Newtons. Formula used to calculate weight is:

W = mg

Mass is defined as the actual matter which a body contains. This term remains constant at every point on the universe. Unit for this term is kilograms.

In the given question, it is given that the gravitational pull of Mars is less than the Earth which means that the value of 'g' is less for Mars. As, weight is directly proportional to the value of 'g', so the weight will be less on Mars than on Earth.

Mass remains constant.

Hence, the correct option for 1 will be Option A and that for 2 will be Option C.
