If a pumpkin has a mass of 2kg on Earth, what would its mass be on the moon?

since 1.62 m/s2 it would weigh lighter

3.2N

Explanation:

As everybody knows that mass is constant, so it will remain the same, on earth as well as moon, even on the sun.

But in the case of weight, it will be changing with the change of gravity and mass, as known from the equation below:

W=mg.

On the earth, the weight of the body having a mass of 20kg will be:

W=mg …….1

(m=2kg, g=9.8m/s)  put in the above equation

W=2×9.8=19.6N

Now to find the weight on the  moon again use eq 1

W=mg

(m=2kg, g on moon=1.6m/s)

W=2×1.6

W=3.2N

So the weight of the body on the moon will be 3.2N

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
