Less work was done. what is one possible reason why this has happened? a. there was more force applied; therefore, there was less movement. b. there was less force applied; therefore, there was more movement. c. there was less force applied; therefore, there was less movement. d. there was more force applied; therefore, there was more movement.

C is the correct answer

ice to water 1 water to vapour 2 latent heat

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
