Alunar vehicle is tested on earth at a speed of 12 km/h. when it travels at the same speed on the moon, is its momentum greater, less, or the same

Momentum is defined as product of mass and velocity

so it is

so here since velocity will remain same as that is on the surface of earth

As well as the mass is always conserved

so here neither mass nor the velocity will change when it is moving on moon

So the momentum will remain unchanged and remain the same

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
