Bailee explained that when traveling to the moon, he needs to pack light because the weight of objects on the moon is the same as their weight on Earth. The mass of the objects is what changes when the gravitational pull changes. Is Bailee correct in his explanation?(1 point)
Responses
Bailee is incorrect. Both the mass and weight will stay the same.

Which equation describes the mass of an object in relation to its volume and density?(1 point)
Responses
m=D/V m is equal to cap d over cap v
m=D+V m is equal to cap d plus cap v
m=D×Vm=D×V
m=V/D m is equal to cap v over cap d
m = D × V
