Adog weighs 70 n on earth. if the dog was sent to moon, how would it's weight change

Well first use the equation w=mg so if he is 70N you plug that in for w. The gravity on eartg is 9.8. So 70=m(9.8) m= 7.14

Now on the moon the gravity is 1.6m/s s use the mAss u previously found and plug it in. 7.14(1.6)=w w= 11.42 so the weight changes on the moon and earth but the mAss remains the same.

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.
