When wax is heated, it turns into a liquid. How are the wax molecules affected by this change of state? The molecules gain energy
The molecules lose energy
The molecules move closer to one another
The space between the molecules increase
The space between the molecules decrease

the CORRECT answer is the "molecules gain energy" because with heating comes energy transferring into the wax molecules. and "the space between the molecules increases" because the molicules will want to space apart because of the heat

Explanation:

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
