Jeff uses a solar cell to run a small motor. What energy transformation occurred? (A) Light to electric to potential
(B) Light to electric to kinetic
(C) Electric to solar to kinetic
(D) Kinetic to electric to mechanical

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

third one with arrows on top of each other going the same direction
