Which has more pe an elephant 2 meters in the air or an elephant 10 meters in the air? explain.

The higher up an object is the greater its gravitational potential energy so an elephant 10 meters in the air would have greater potential energy than and elephant 2 meters in the air.

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
