Base your answer to the following question on the diagram below which shows a 1-kilogram stone
being dropped from a bridge 100 meters above a
gorge
Ikg
100m
1
As the stone falls, the gravitational potential
energy of the stone
A) decreases C) remains the same
B) increases

think its the third option

measuring things 1 litre of water

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
