Which surface will most likely allow marisa to push a box with the least amount of force? a.) a brick-paved sidewalk b.) a pebbly, concrete path c.) a carpeted floor d.) a smooth tile floor

It's either C. or D. its either one just keep reading the question over and over okay it will help i promise

the answer is c.a carpeted floor

b.transmitters send radio waves, and receivers capture radio waves.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
