Gravity on earth is 9.8 m/s2,and gravity on the moon is 1.6 m/s2. so, if the mass of an object on earth is 40 kilo, it’s mass on the moon is _ kilo and it’s weight on the moon is _ newton’s

It's Mass will remain 40 kilo because mass is amount of matter in an object which does not change. However, weight will and its weight on the moon wi0l be about 65.9 Newtons

Gravity has no effect on mass, and mass doesn't change, no matter where you are.

40 kilograms is 40 kilograms ... On Earth, on the moon, or floating "weightless" on your way from one to the other.

i think it’s c but i might be wrong. if i am let me know! have a good rest of your day as well!
