Which statement correctly compares weight and mass?
A Both depend on the force of gravity pulling on an object.
B. The basic unit of both in the metric system is the kilogram.
C. Mass varies with location, but weight does not.
D. Weight varies with location, but mass does not.

Option D. Weight varies with location, but mass does not.

Explanation:

To know which option is correct, it is important that we have a background knowledge of mass and weight.

A brief summary of the difference between mass and weight is given below:

1. Mass is the quantity of matter present in an object while weight is the gravitational pull on an object.

2. The SI unit of mass is kilogram Kg) while that of weight is Newton (N)

3. Mass is constant while weight varies by location.

4. Mass can measured using a chemical balance or beam balance while weight can be measured using a lever or spring balance.

With the above information, we can see that mass of an object is always but the weight varies by location.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
