In which situations is work being done? Hannah leans against her locker, but it doesn’t move.

Andy’s car rolls down a hill with the engine off.

A wind turbine stands still on a sunny, windless day.

A balloon expands as it is heated by the sun.

James pedals a stationary exercise cycle that doesn’t move.

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

i believe the answer is electric potential.
